FRM220-SERIAL-SC02A RS-232, RS-485, RS-422 over single strand fiber BiDi media converter, 20Km, A type

The FRM220-SERIAL-SC20A provides a fiber converter solution to extend RS-232 or RS-485/422 transmission distance up to 20km over a single strand of single mode 9/125um fiber. You must pair the A model using Tx:1310/Rx:1550nm with the complementary FRM220-SERIAL-SC20B model having Tx:1550nm and Rx:1310nm instead. The converter is equipped with multiple interface circuits, for connection to RS-232, RS-423, or RS-485/422 (2 or 4 wire). The FRM220-SERIAL secures data transmission over EMI resistant fiber at speeds up to 256kbps for RS-232 or up to 1024kbps for RS-422/485. When the FRM220-SERIAL is linked to the FRM220 series chassis equipped with FRM220-NMC management card, it allows network administrators/engineers to get greater functionality through advanced SNMP/Web/In-band management features. The network administrator can manage any converter module from anywhere on the network, detect any link loss and maintain each loop. The uniqueness of FRM220 series is given by the ability to co
