The network module has modular optics supporting the Cisco pluggable optical modules (POMs) and Cisco Small Form-Factor Pluggables (SFPs), simplifying the selection of network modules from six offerings to one. The SFPs support STM-1 framing standards over multimode, single-mode intermediate-reach, and single-mode long-reach fiber-optic interfaces. The module is a single-port module with LC-type connector. The single-mode SFPs combined with the ATM network module provide high-speed trunking for users with access to a fiber WAN, whereas multimode is ideal for connecting high-speed servers, switches, or hubs equipped with OC-3/STM-1 fiber connections.
