E3/DS3/STS-1 Fiber Optic Modem

View : 592
Type : E3/DS3/STS-1 Fiber Modem
Description :

The E3/DS3/STS-1 fiber optic modem directly modulates the E3/DS3/STS-1 data signal to single-mode or multi-mode optical fiber.


The E3/DS3/STS-1 fiber optic modem directly modulates E3/DS3/STS-1 data signal to single-mode or multi-mode optical fiber with a transmission rate of E3(34.368Mbps±20ppm)/DS3(44.736Mbps±20ppm)/STS-1(51.84Mbps±20ppm).


E3/DS3/STS-1 Fiber Optic Modem E3/DS3/STS-1 Fiber Optic Modem


Based on self-copyright IC;

Integrated Transmitter, Receiver, and Jitter Attenuator for DS3, E3, and STS-1;

Provide 2 fiber interface 1+1 protect (APS) functions, one is the main fiber port, and the other is the backup port (Optional).

Provide 75 Ωunbalance coaxial cable, B3ZS/HDB3 decoding, and loss-of-signal monitoring;

After strict testing and a practical verification system, completely comply with protocol ITU-T G.703, G.7;

Have 3 Loop Back Mode: Fiber interface Loop Back (ANA), E1 interface Loop Back(DIG), Command the remote E1 interface Loop Back (REM);
