Cisco SFP and SFP+ Transceiver Module Installation Notes
78-15160-07
Overview
Note For the GLC-ZX-SM, the minimum attenuation between the transmit bore (TX) and the receive bore
(RX) is 8 dB. When using shorter distances of single-mode fiber cable, you might need to insert an inline
optical attenuator in the link to avoid overloading the receiver.
Copper SFP transceiver modules can operate at 10, 100, or 1000 Mbps on some Cisco devices. To find
the supported speeds for the 1000BASE-T SFP transceiver modules in your Cisco device, see the
Compatibility Matrix for 1000BASE-T Small Form-Factor Pluggable Modules.
