FIC-1POS

Introduction FIC-1POS, the 1-port SDH/SONET interface card, supports interface rates up to 155.52 Mbps (STM-1/OC-3).

The FIC-1POS uses the protocols such as PPP, Frame Relay and HDLC at the data link layer and IP at the network layer. It allows direct transmission of packets over SONET/SDH. It supports:

■Four types of SFP: multi-mode short-haul (1310 nm), single mode medium-haul (1310 nm), single mode long-haul (1310 nm), and single-mode ultra-long haul (1550 nm).

■155.52 Mbps fractional interface
