High Reliability 4E1 Fiber Optic Multipexer OT120

Introduction:
OT120 series are a low cost and high performance optical line transmission equipment, witch combines up to four E1 channels into an optical data stream for transport over single mode or multimode fiber optic cables. Several transmitter options for different fiber cable types and wave-lengths are available. This optical line equipment is developed for transmission in access networks, corporate networks, dedicated networks for railway and power companies etc.
Features:
1. Advanced and compact design that performs E1 multiplexing & de-multiplexing and provides a 8.192Mbit/s
2. Optical interface in a single unit
3. Built-in AC/DC or DC/DC converter and supervisory microprocessor
4. Digital clock and data recovery for E1 & optical signal
5. Provides visible and audible alarm indications
6. Local & remote loop back controls for diagnostics and troubleshooting
7. Order-wire channel for end to end installation and maintenance
8. Low power consumption
9. High reliability
