The FRM220-4G-2S optical regeneration device is designed for high-performance signal transmission, offering both re-amplification and re-shaping functions. It supports a wide range of protocols with bit rates ranging from 28 Mbps to 4.25 Gbps, including Fast Ethernet, Gigabit Ethernet, OC-3, OC-6, OC-12, OC-24, OC-48, and various Fiber Channel standards (FC-1, FC-2, FC-4). This versatile device allows for network management through Web, Telnet, and SNMP interfaces when integrated into the central FRM220 chassis, providing real-time monitoring of the converter card’s status, type, version, fiber link status, and alarms. It features advanced functions such as Link Fault Pass-Through (LFPT), Auto Laser Shutdown (ALS), and digital diagnostic monitoring for SFP modules. Local configuration can be performed through a DB9 console port, and it also supports optical repeater functions with facility loopback capabilities on both client and line sides. The FRM220-4G-2S ensures reliable performance with error detection and the ability to detect transceiver transmitter alarms.
