TFT1000 forward laser transmitter
3U height
Origina famous brand DFB laser
AGC,APC,ATC
SNMP, with network transponder

Summarize

    TFT1000 optical transmitter has small size, compact structure characteristics, cooperate with TNE1000 optical platform to make a high performance indoor transmission equipment.

    TFT1000 optical transmitter adopt in-band optical isolator of high linearity, low noise DFB laser imports (DFB) as optical source, adopt the company’s newly developed full-band pre-distortion circuit, significantly improved the laser non-linear index. TFT1000 optical transmitter built-in microprocessor to monitor all the work status of DFB laser paraments, and transmit to TNE1000 system controller through the trunk. System controller intelligent function provides a good internal working environment to TFT1000 module, VFD display of the platform can monitor the work status. In this condition, TFT1000 module can  be excellent performance, and has very high reliability and stability. 

 

Features

Orignal imported high linearity DFB laser, excellent link performance.Excellent AGC(automatic gain control), APC(automatic power control), ATC(automatic temperature control) function, adapt to wide range RF input, to ensure the laser output power stability and regular life working.Wide band pre-distortion circuit, the link index is more superiorAGC,MGC optional, according to the needs of the network to chooseComprehensive protection circuitry.( start delay protection, working status indicator and alarm, RF over-active turn-off and alarm, etc.)Real-time transmit to the system platform for all kinds of working status parameters and display them.Superior overall unit design, to ensure long-term safety and reliability of the equipment.Open network management interface to meet the national standard, compliance with SCTE HMS network management standard
