Microwave Photonic Systems, Inc. Bidirectional Fiber Optic Modem MP-4235TRX

The MP-4235TRX is a compact fiber optic transceiver operating in the 1310/1550 WDM wavelength band. The MP-4235TRX is configurable with your choice of data protocol formats. The options include either RS-232, RS-422 or RS-485 digital interfaces. The MP-4325TRX is specified as a pair of complimentary wavelength pass band devices that function in an end to end link for communications over one fiber allowing for any two pieces of asynchronous serial equipment to communicate full or half duplex over distances up to 20 km.Each MP-4325TRX module consists of a Distributed Feed Back (DFB) laser; Pin Photo-Diode (PIN) optical detector and a Wave Division Multiplexing (WDM) thru port configured with a user specified optical connector. The MP-4325TRX supports both the Transmit and Receive data lines and all serial connections are provided on the same DB-9 female connector, while the single mode fiber is connected via FC/APC connectors. The MP-4325TRX supports data signals rates of up to 128 Kbps. In addition to providing end-to-end optical link transmission, the MP-4325TRX can be employed as a protocol converter allowing a RS-232 signal transmitted from one end to be converted to RS-422 at the other end. This capability eliminates the need for additional protocol converting hardware thus minimizing system architecture support requirements.
