Chapter 1 Introduction

1.8.23 FRM220-FOM04 4xE1/T1 +100M Ethernet Fiber Optical Multiplexer Card

FRM220-FOM04 is a modular design for 4xE1/T1 + Fast Ethernet multi-service to dual strand fiber PDH multiplexer.

FRM220-FOM04 provides E1/T1 transmission transparently and pure 100Mbps Fast Ethernet simultaneously. The fiber optic line is based on the SFP technology that allows the flexible use of Multimode or Single mode lines and enables the support of different wavelengths and distances. The use of bi-directional SFPs maximizes the utilization of the fiber optic line and results in saving line costs. With SNMP and Web-based management in the

FRM220, the Network administrator can monitor, configure and control the activity of each card in the chassis.
