Product Description
Optical Transmitter Forward TFT1000M AGC 1U 1310 nm Forward Optical Transmitter
Overview
TFT1000M series optical transmitter with high performance, high quality to transmit analog RF signal. The microprocessor as the core of control circuit, the processing circuit and the internal monitoring and network management circuit ensure the best working status of the optical transmitter.Front panel LCD screen clearly indicates the working status and various parameters easily for local operation and monitoring.TFT1550M directly modulated optical transmitter works generally within 10 km, the largest no more than 20 km. Its main application is to cooperate with EDFA. It also supports the front edge of IP QAM and the inter-cut of local programs.
Functions of MGC/AGC, channel total power conversion functions are convenient for light spot network debugging and maintenance. High-quality RF channel AGC control circuit, 72 ~ 82dBuV wide range of RF input ensure the stability of the laser output power and long life of the laser. It supports dual hot backup power supply and hot plug with high reliability.
Equipment with high reliability and easy operability,follows international NM standard protocol,and monitors status and diagnose faults directly through Ethernet.
Features
l Adopting high-quality,high-linearity DFB laser module and unique predistortion circuit ensure good link performance.
l Excellent APC (automatic power control), ATC (automatic temperature control) function ensures stability and long working life of laser.
l High-quality Rf-excited circuit
l MGC/AGC two functions, channel total power conversion functions, convenient for debugging and light spot network maintenance
l High-quality power supply provides power with wide voltage range.
l perfect protection circuit (start- up time delay, working parameter alarm, shutting off the alarm when RF-excited is too high or too low )
l High-quality RF channel and AGC control circuit are suit for wide range of RF input signal.
l Supporting displaying average and total power of each channel through master controlling interface.
l Quality plug type switch power supply, supporting double hot backup power supply
l Perfect LCD display controlling and NM status monitoring interface ensure convenient local computer monitoring.
l Excellent cooling design ensures the long-time reliability of equipment

Remark:
1.C/N is less than the expected link loss. 10 km optical fiber, 59 PAL - D channel, arranging 35 paths QAM64 digital carrier within 550 ~ 862 MHZ and the level is lower than 6 dB.
Receiver noise: 8PA√HZ
optical detector sensitivity:0.85 mA/mW,
typical values of receiver input optical power : -1.0 dBm .If receiver optical input power is not 1.0 dBm, carrier to noise ratio (C/N) will be changed.
2. All kinds of optical transmitter output power is nominal value.
