The OM-10B modem transmits and receives serial asynchronous and synchronous data over a pair of optical fibers. The interface can be set to EIA530, EIA530A, RS232, or RS485. The modem is data rate transparent from DC to 128K Baud.
Data, two clocks, and all hand-shake lines are passed across the link. There are two models of the OM-10B, a DCE and a DTE. The OM-10B-DCE connects to Data Terminal Equipment such as a computer.
It has an on-board bit rate generator which outputs standard clock frequencies, if a clock is desired for synchronous communication. The OM-10B-DTE connects to Data Communication Equipment such as a modem.
We're very happy with the multiplexers that you supplied. The nature of the customer’s installation means that we won’t hear general feedback unless things go wrong – we’ve not received any complaints so assume that there have not been any problems. We found the equipment straight forward to set up using the supplied documentation.
