OT-04 unit/OT-03 board

      • Designed for simultaneous transmission (inserting/extraction) of up to 16 E1 streams and Ethernet traffic via one or two 100Base-TX interface(s) over single-mode fiber optic.

      • Maximum Ethernet traffic rate is 50 MB/s via each interface.

      • When working only with E1 streams the unit provides through-connection of up to 73 E1 streams.

      • Plesiochronous operation is provided for E1 streams.

      • Changeable SFP transceiver allows using the board for different lengths of line link.

      • The unit supports network monitoring system.

      • Power supply is 36...72 VDC.

      • Unit’s construction is top-desk modem 1U high for installation into 19" cabinet.

      • Option of construction with face panel (OT-03) for installation into M60 flexible multiplexor is available.
