Description
E1 fiber optic modem is to modulate E1 signal to single or multi-mode fiber converter. Suit for transmit additional management data channel in different fibers. The fiber for transmit data can be used to monitor and control local and remote devices, and no collision will occur. The E1 to fiber converter can support framed E1 or non-framed E1.
E1 Fiber Optic Features
● Based on self-copyright IC, and software content is high.
● Provide 3 type loop functions: local (ANA), loop to remote (DIG), command loop (REM).
● PBRS Code testing function, convenient for install and test devices.
● Framing or non-framing mode in option
● Support the loop back of local analog/digital interface
● Remote rate adjustment to remote device (in primary clock status) when local terminal is in primary clock status.
● AC220V or DC-48V power built-in
● It can support SNMP management in our chassis installation

The three loopback options—local, toward the remote end, and remotely commanded—are a strong point for narrowing down link problems. Built-in test-pattern capability is another useful feature for installation and maintenance. These diagnostic tools add practical value to an E1 fiber modem.
