1550nm external modulated optical transmitter

The PTT5101


Description

The PTT5101 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

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

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

■ Unique simultaneously SBS/SPM suppressing

■ Front panel LCD display

■ Microprocessor control and monitor

■ RS-485 interface for remote monitoring and control

■ 45~870 MHz bandwidth

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

■ Changeable cooling fan.

Application

■ Broadcast or narrowcast transmission at long or extended distances

■ Hub Interconnects Of Redundant Ring Architectures

■ Video Overlays In FTTx Networks.
