Things About Cisco SFP Compatibility Matrix That Wiki Can’t Tell You

Transceiver module is the essential device of a network architecture. As a famous manufacturer of optical products, Cisco published a set of copper SFP transceiver modules to support copper networking. Here focus on Cisco SFP compatibility matrix to present a comprehensive Cisco SFP datasheet for you.

Overview of Cisco Copper SFP Transceiver Module

SFP stands for small form factor pluggable. Copper SFP transceiver is a hot-pluggable transceiver with RJ45 port, so it’s also called SFP RJ45 transceiver. SFP RJ45 transceiver supports 10/100/1000 BASE rate over Cat5 cables. In addition, RJ45 copper transceiver is usually used for transmitting data in a short distance, due to its transmission distance ranging from 10 to 30 meters or from 80 to 100 meters. And Cisco 1G SFP, copper and RJ45 Ethernet cables are much cheaper than the fiber ones, so it’s wise to choose a copper SFP transceiver to make use of the existing cabling system to optimize your network instead of using the fiber cables.

How to Choose A Cisco Copper SFP Transceiver Module

When you decide to buy a copper SFP transceiver, the quality and price matter a lot. But the price between OEM and the third party suppliers varies greatly. If you have plenty of money, you can order one directly from Cisco. If you search for a cost-effective solution, then the third party is a good choice. As for the quality, there are not many differences between Cisco and the third party’s products, because all products must meet the strict standards or MSA (Multisource Agreement). So it’s a wise decision to buy a copper SFP transceiver from a third party. Here I recommend you some copper SFP transceivers from FS.COM, whose transceivers are all tested before shipping.

Cisco GLC-T Compatible 1000BASE-T SFP Transceiver

This GLC-T transceiver is a typical RJ45 transceiver, which is used for Cat5 wiring. The max data rate is 1000Mbps and the max cable distance is 100 meters, which is suitable to connect different switches or routers in a data center. It’s compatible with most Cisco switches and some FS switches like S5800-48F4S Gigabit SFP switch.

Cisco GLC-TA Compatible 10/100/1000BASE-T SFP Transceiver

Similar with GLC-T SFP, but this copper transceiver supports 10/100/1000 auto negotiation. And the operating temperature is different. It is an extended temperature range from -5 to 85°C, while GLC-T is from 0 to 70°C. Furthermore, it also operates on standard Cat5 unshielded twisted-pair copper cabling of link lengths up to 100 meters.
