Fiber Optic Modems

The FIB1-Serial/FDC is a asynchronous fiber optic Ring/ Daisy-chain modem which operates over a fiber link to connect remote terminals and computers, connected in multi-drop, to a central host. The FIB1-Serial/FDC allows for totally redundant, fault tolerant, self-healing operation, providing uninterrupted communications between networks nodes ...more

Models 232FLST and 9PFLST allow any two pieces of RS-232 equipment to communicate full or half duplex over two fibers at a distance up to 2.5 miles with no external power. RS-232 data signals at up to 115.2 kbps. RTS/CTS handshake lines are supported. The 232FLST and 9PFLST provide a transparent cable connection between devices with the EMI/RF ...more
