The OPTEL2 is used to extend a two wire telephone line using optical fibers. The OPTEL2-SL connects to a plain old telephone at one end of a link, and the OPTEL2-CO connects to a CO or PBX at the other end of the link. Connecting two OPTEL2-SLs together creates a dedicated voice link (order-wire). Either single or multimode fiber may be used interchangeably.
The OM15E transmits an E1 telephony signal across a pair of optical fibers. At the far end, the electrical signal is regenerated by a second OM15E. Alarm contacts flag power supply or optical link failure. A second set of modems may be connected to the first in hot-standby mode when
redundancy is required. This very robust modem is MIL461 certified.
The OM15B transmits a T1 or E1 signal over a pair of fiber optic cables. At the far end, the signal is regenerated by a second OM15B. The modems offer a number of features including dry contact sensing and an RS-232 auxiliary channel.
