The MOD-FE1 optical fiber modulator and demodulator is a high-performance E1 optical fiber modulator and demodulator. It modulates a framed or unframed E1 data signal directly onto single-mode or multimode optical fiber and transmits it into an optical cable line. At the other end of the optical cable, the optical signal is demodulated into a framed or unframed E1 data signal. The E1 port can be directly connected to the E1 port of image, data terminal, multiplexer, switch, and router WAN port, and can be used to form a dedicated network or to connect to a wide area network.
This manual introduces the MOD-FE1, a high‑performance E1 optical fiber modem that modulates E1 signals onto single‑mode or multimode fiber. It outlines compliance with ITU‑T G.703/G.704 standards and describes both independent and rack‑mount configurations.
The guide covers technical specifications, panel descriptions, configuration jumper settings, and common troubleshooting steps, helping users install, configure, and maintain the device effectively. This manual is written in Chinese.
