Cisco 1000BASE-T SFP Modules
Note The 1000BASE-ZX GBIC module and SFP modules provide an optical power budget of 21.5 dB. You
should measure your cable plant with an optical loss test set to verify that the optical loss of the cable
plant (including connectors and splices) is less than or equal to 21.5 dB. The optical loss measurement
must be performed with a 1550-nm light source.
Cisco 1000BASE-T SFP Modules
The 1000BASE-T (GLC-T) SFP module is compliant with IEEE 802.3:2000 and plugs into a standard
Gigabit Ethernet SFP module port. It operates on standard Category 5 wiring and has an RJ-45
connector.
See your router installation and configuration guide to determine which routers support the GLC-T SFP
module.
