Question 1

What data rate does the GLC-TE support?

Accepted Answer

The module supports 1 Gbps full-duplex speed. It auto-negotiates with link partners for seamless connectivity.

Question 2

What is the Cisco GLC-TE?

Accepted Answer

The Cisco GLC-TE is a 1 Gigabit copper SFP transceiver module that converts an SFP port into a standard RJ-45 copper Ethernet interface. It supports 1000BASE-T operation over Cat5 or better twisted-pair cable up to 100 metres. The GLC-TE allows switches and routers with SFP slots to connect to devices using standard copper cabling, making it useful wherever fibre infrastructure is absent or unnecessary.

Question 3

What does GLC-TE stand for?

Accepted Answer

GLC stands for Gigabit LAN Card, and T refers to twisted-pair copper, following the IEEE 1000BASE-T designation. Unlike fibre SFP modules such as the GLC-SX-MMD or GLC-LH-SMD, the GLC-TE is a purely electrical module with no optical components and no fibre connector. The T designation appears consistently across Cisco's copper SFP variants to distinguish them from fibre optic counterparts in the same product family.

Question 4

Is the GLC-TE an optical or copper module?

Accepted Answer

The GLC-TE is a copper module. It contains no optical components and does not require fibre cabling of any kind. It connects via a standard RJ-45 interface using Cat5 or better twisted-pair cable. There is no wavelength, no optical transmitter, and no fibre connector associated with the GLC-TE. It operates entirely over copper electrical infrastructure, which makes it fundamentally different from any fibre-based SFP module in the Cisco range.

Question 5

Where does the GLC-TE sit in Cisco's 1G SFP product range?

Accepted Answer

The GLC-TE is the copper member of Cisco's 1G SFP family. Alongside optical counterparts such as the GLC-SX-MMD (multimode fibre, 550m) and GLC-LH-SMD (single-mode fibre, 10km), it provides flexibility when the target device or installed cabling is copper RJ-45. The GLC-TE fills the gap in deployments where SFP slots are available but the connected device or wiring infrastructure is copper, not fibre.

Question 6

What is the maximum distance the GLC-TE supports?

Accepted Answer

The GLC-TE supports a maximum distance of 100 metres over copper twisted-pair cabling, in line with the IEEE 802.3ab 1000BASE-T standard. This is the same limit as any standard copper Gigabit Ethernet port. The 100-metre figure covers the entire cable run including patch cables at both ends. For connections that need to exceed 100 metres, a fibre SFP module with a media converter or switch at each end is required.

Question 7

What cabling does the GLC-TE require?

Accepted Answer

The GLC-TE requires Cat5 or better twisted-pair copper cabling. For reliable Gigabit operation at the full 100-metre distance, Cat5e or Cat6 is recommended, as original Cat5 can be marginal for Gigabit speeds over longer runs. Cat6A and Cat7 also work correctly. All four pairs of the cable must be connected, as 1000BASE-T uses all four pairs simultaneously to achieve full Gigabit throughput.

Question 8

What connector type does the GLC-TE use?

Accepted Answer

The GLC-TE uses a standard RJ-45 connector, the same 8-position modular connector found on all copper Ethernet ports and patch panels. Any standard Cat5e or Cat6 copper patch cable with RJ-45 terminations at both ends is compatible. No special cables, adapters, or fibre patch leads are required. The RJ-45 interface on the GLC-TE is no different from that of any other copper Gigabit Ethernet port.

Question 9

Does the GLC-TE support auto-negotiation?

Accepted Answer

Yes, the GLC-TE supports IEEE 802.3 auto-negotiation for both speed and duplex. It negotiates 10, 100, or 1000 Mbps with the connected device automatically, selecting full or half duplex based on both link partners' capabilities. For optimal performance, both ends should be set to auto-negotiate. Forcing speed and duplex on one end while leaving the other on auto is a common cause of duplex mismatch and degraded link performance.

Question 10

Does the GLC-TE support Digital Optical Monitoring?

Accepted Answer

No, the GLC-TE does not support Digital Optical Monitoring. DOM is a feature of optical fibre transceivers that monitors laser power, temperature, and voltage. Because the GLC-TE is an electrical copper module with no optical components, there are no optical parameters to report. The "show interfaces transceiver" command on a Cisco switch will return no DOM data for a port fitted with a GLC-TE.

Question 11

What is the GLC-TE used for?

Accepted Answer

The GLC-TE is used to connect copper Ethernet devices to a switch or router that provides only SFP ports. It converts an SFP slot into a standard RJ-45 copper port. Common deployments include connecting servers, firewalls, NAS devices, and legacy network equipment to SFP-based switches using existing copper Cat5e or Cat6 cabling, without needing to install fibre or a media converter at either end.

Question 12

When would I use the GLC-TE instead of a built-in RJ-45 port?

Accepted Answer

The GLC-TE is useful when all dedicated RJ-45 ports on a switch are occupied but SFP slots remain available. It converts a spare SFP slot into an additional copper port, extending the switch's copper port count without adding another switch. It is also used on switches that are primarily SFP-based with few built-in RJ-45 ports, where a specific device needs a copper connection and fibre is not practical.

Question 13

Is the GLC-TE suitable for server-to-switch copper connections?

Accepted Answer

Yes, the GLC-TE is a practical choice for connecting a server to a switch's SFP uplink port over copper cabling where the server has a standard RJ-45 NIC and 1G throughput is sufficient. For server-to-switch links within 100 metres where fibre is not installed, the GLC-TE provides a straightforward copper solution without requiring fibre transceivers or additional cabling infrastructure on either end.

Question 14

Can the GLC-TE be used in Cisco combo SFP/RJ-45 ports?

Accepted Answer

Yes, the GLC-TE works in both dedicated SFP slots and combo SFP/RJ-45 ports. On a combo port, inserting the GLC-TE activates the SFP side and automatically disables the associated built-in RJ-45 port, as Cisco combo ports operate in one mode at a time. This is standard Cisco combo port behaviour and applies to the GLC-TE the same way it would to any other SFP module inserted into a combo slot.

Question 15

What Cisco platforms is the GLC-TE compatible with?

Accepted Answer

The GLC-TE is compatible with Cisco Catalyst 2960, 3560, 3750, 3850, 4500, and 6500 series switches, Cisco ISR 2900, 3900, and 4000 series routers, and other Cisco devices with SFP slots. It is also compatible with Cisco Catalyst 1300 and CBS350 series SMB switches that include combo uplink ports. Always verify against Cisco's compatibility matrix for your specific platform and IOS version before ordering.

Question 16

Does the GLC-TE work in Cisco Catalyst 1300 and CBS350 combo uplink ports?

Accepted Answer

Yes, the GLC-TE is compatible with Cisco Catalyst 1300 and CBS350 series switches that include combo SFP/RJ-45 uplink ports. These SMB switches typically provide two combo uplinks where either a fibre SFP module or a copper module like the GLC-TE can be inserted. This flexibility makes the GLC-TE a useful option when copper uplinks are preferred for connecting to an upstream switch or router.

Question 17

Can the GLC-TE be used in non-Cisco equipment?

Accepted Answer

The GLC-TE is encoded for Cisco platforms and will not function correctly in non-Cisco switches or routers. Equipment from Juniper, HPE, Huawei, and other vendors requires their own vendor-encoded copper SFP modules. Using a Cisco-encoded GLC-TE in non-Cisco equipment typically results in the module not being recognised or the port not initialising. Third-party compatible copper SFP modules programmed for the specific target platform are the correct solution for non-Cisco deployments.

Question 18

Is the GLC-TE compatible with older Cat5 cable installations?

Accepted Answer

The GLC-TE works with Cat5 cabling, but reliable Gigabit speeds over the full 100-metre distance require Cat5e quality or better. Original Cat5 can be marginal for 1000BASE-T at longer runs due to crosstalk limitations that were not fully addressed in the original Cat5 standard. For runs under 30 metres, Cat5 generally performs adequately. For new installations, Cat5e or Cat6 is recommended to ensure consistent full-speed performance.

Question 19

What is the difference between the GLC-TE and GLC-SX-MMD?

Accepted Answer

The GLC-TE is a copper module using an RJ-45 connector over Cat5e cable up to 100 metres. The GLC-SX-MMD is an optical module using multimode fibre and an LC connector up to 550 metres. They both deliver 1G throughput but use entirely different physical media. Use the GLC-TE where copper cabling is in place and distance is within 100 metres. Use the GLC-SX-MMD where multimode fibre is installed or greater reach is needed.

Question 20

What is the difference between the GLC-TE and GLC-LH-SMD?

Accepted Answer

The GLC-TE provides 1G over copper RJ-45 cable up to 100 metres. The GLC-LH-SMD provides 1G over single-mode fibre with an LC connector up to 10 kilometres at 1310nm. The GLC-LH-SMD is used for inter-building and campus connections where copper reach is insufficient. If your link is within 100 metres and copper infrastructure is already installed, the GLC-TE is simpler and more cost-effective. For anything beyond 100 metres, fibre is required.

Question 21

When should I choose the GLC-TE over a fibre SFP module?

Accepted Answer

Choose the GLC-TE when link distance is 100 metres or less, Cat5e copper cabling is already installed, and the connected device has a standard RJ-45 port with no fibre capability. It is also the right choice when you want to avoid the cost of fibre transceivers and patch cables for a short point-to-point connection. Fibre SFP modules are preferable when distances exceed 100 metres, electromagnetic interference is a concern, or fibre infrastructure is already in place.

Question 22

How does the GLC-TE compare to the SFP-GE-T?

Accepted Answer

The GLC-TE and SFP-GE-T are both Cisco 1000BASE-T copper SFP modules with near-identical specifications: RJ-45 connector, 100-metre reach, Cat5e or better cabling required, and no DOM support. The difference lies in platform compatibility listings, as some Cisco platforms reference one part number as preferred over the other in the compatibility matrix. Both perform identically in operation. Check the Cisco compatibility matrix for your specific platform to confirm which part number is officially listed.

Question 23

Question 29

Is a refurbished GLC-TE tested before dispatch?

Accepted Answer

Yes, refurbished GLC-TE units at ORM Systems are tested before dispatch. Testing confirms correct electrical function, auto-negotiation capability, and physical integrity of the module and RJ-45 connector. Since the GLC-TE is a copper module, testing focuses on electrical performance rather than optical parameters. This ensures the module initialises correctly in a supported Cisco platform without interface errors after installation.

Question 30

What certifications does the GLC-TE carry?

Accepted Answer

The Cisco GLC-TE meets FCC Class A and CE electromagnetic compatibility standards, along with RoHS compliance for restriction of hazardous substances. It conforms to the IEEE 802.3ab 1000BASE-T specification. These certifications make it compliant with regulatory requirements in the UK, EU, and US, and suitable for deployment in regulated enterprise, public sector, and educational network environments.

Question 31

How do I install the GLC-TE in a Cisco switch or router?

Accepted Answer

Insert the GLC-TE into an available SFP slot with the label facing up until the module clicks firmly into place. Connect a standard Cat5e or Cat6 copper patch cable into the RJ-45 port on the module. The Cisco device detects the module automatically without requiring a reboot. Confirm detection with "show interfaces" or "show inventory." On combo ports, the built-in RJ-45 side of that port deactivates when the GLC-TE is inserted into the SFP slot.

Question 32

Does the GLC-TE require any Cisco IOS configuration after installation?

Accepted Answer

No special configuration is required. The GLC-TE is automatically detected by Cisco IOS and IOS-XE on insertion and the interface initialises for standard copper Ethernet use. Apply standard interface settings as needed, such as VLAN assignment, speed, duplex, or port security. Since the GLC-TE supports auto-negotiation, manual speed and duplex settings are typically unnecessary unless connecting to a device with fixed interface settings.

Question 33

Does the GLC-TE require a licence to operate?

Accepted Answer

No, the GLC-TE does not require a licence. It is a hardware module that activates automatically when inserted into a compatible Cisco SFP port. Cisco licensing relates to software features such as routing protocol tiers, advanced security, and management capabilities, not to physical transceiver hardware. The GLC-TE is plug-and-play on any compatible Cisco platform with no licence activation required.
