Product Details

1550 External Modulated Transmitter

Description

The PTT5101E external modulated 1550nm transmitter is designed for HFC networks applications. It can optionally be equipped with an integrated EDFA for CATV applications such as super-trunk, hub Interconnects, video overlays In FTTx networks .

The unit is available in a standard 19”,1 rack unit chassis , with dual optical output, optional ITU-T wavelength for DWDM networks.

Features

l Selectable AGC (automatic gain control) or MGC (manual gain control)

l Accepts low signal input levels (75dBμV/Channel @ 77 ch NTSC)

l Unique simultaneously SBS/SPM suppressing

l Front panel LCD display

l Microprocessor control and monitor

l RS-485 interface for remote monitoring and control

l 45~870 MHz bandwidth

l Patent RF pre-distortion circuit for excellent CNR and low distortion performance

l Changeable cooling fan

Application

l Broadcast or narrowcast transmission at long or extended distances

l Hub Interconnects Of Redundant Ring Architectures

Video Overlays In FTTx Networks.
