Last Mile (Local Loop)

Framed E1 Fiber Modem
NIFT-FE

Is a fiber-optic modem to transmit E1 (2.048 Mbps) signals over multi-mode or single-mode fiber optic media. This unit is transparent to frame, and transmits data using any frame pattern with HDB3 E1 coding signals.

NIFT-FE complies with ITU-T G.703 G.704 standard,supports non-fractional or fractional E1 mode,E1 timeslot can be selected freely under fractional mode.
