Chapter 1 Introduction
1.7.13 FRM220-155MS SM/MM, MM/SM converter / repeater
The FRM220-155MS is a fiber to fiber optical media converter and repeater that allows data rates up to
155Mbps. FRM220-155MS supports 2R regeneration, which consists of re-amplification and reshaping. This
converter is compatible with fiber interfaces such as 100Mbps Fast Ethernet, 155Mbps STM1 and OC3. The
FRM220-155MS works well with FRM220-CH20 chassis as slide-in card or with FRM220-CH01, one slot chassis
as a stand-alone fiber converter. When the FRM220-155MS card is placed in the FRM220 rack with SNMP
management, the management can view the converter card's status, type, version, fiber link status and alarms. The
card can be configured to enable or disable the port, reset the port or enable/disable Auto Laser Shutdown.
