CXtec NEW COMPATIBLE GIG SX MMF SFP WITH LC CONNECTORS AND LIFETIME WARRANTY Guia De Especificaciones

SFP transceivers that operate with single-strand SMF, have only one optical bore; the other bore is
blocked off.

LC SFPs provide duplex single-mode and multimode connections in supported devices.

lists the

cable specifications for fiber-optic SFP module ports.

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 modules can operate at 10, 100, or 1000 Mbps on some Cisco devices. To find the supported
speeds for the 1000BASE-T SFP modules in your Cisco device, refer to the Compatibility Matrix for
1000BASE-T Small Form-Factor Pluggable Modules.

Copper 1000BASE-T SFP transceivers use standard four twisted-pair, Category 5 cable at lengths up to
328.08 feet (100 meters).
