4000 Router Series Interface Module Guide

NOTE:

MDI stands for Media Dependent Interface of the Ethernet. Typically, the interfaces on the network cards

belong to this type. Cross Media Dependent Interface (MDIX) is usually adopted on hubs or LAN switches.

SIC-1FEF

Introduction

SIC-1FEF is short for 1-port 100 Mbps fiber Ethernet interface module, where FE is short for Fast Ethernet

and F for fiber, indicating an optical fiber interface. SIC-1FEF is used for the communication between the

router and LAN.

SIC-1FEF supports:

• Five types of SFP removable optical interface modules: multimode short-haul (850 nm), single-mode

medium-haul (1310 nm), single-mode long-haul (1310 nm), single-mode long-haul (1550 nm), and

single-mode ultra-long haul (1550 nm).

• 1000 Mbps interface rate

• Full duplex

Interface attributes

The following table describes the interface attributes of the SIC-1FEF. For more information about the

attributes of the optional SFP transceiver modules, see "100-Mbps SFP transceiver module."
