optical fiber transmission system TS100x

Summary:

Be suitable for the development of the structure of double district area broadband network and specialized for meeting the good installation of forward end room equipment. According to the thought of module design of two power modules and eight function modules in 19 5U height criterion machinery to supply an intelligent assembling control system which monitor the practical parameter and give the automatic warning signal when problems to be made suddenly. The structure of two power supply hot backup coordination with warm system controlled by micro computer to improve the reliability of system. Set with RS-485 and RS-232 web tube transmission connector, assemble controlling conveniently. It is the first-choice of Bi- directional HFC broadband network

TS-1001 Performance Characteristic

The new style of Switching Power, reasonable volume, Low power consumption, high efficiency of transformation and Power output; There are two WOS-2001 Module at max under hot backup operating.

TS-1002 Optical Transmitter module Performance Characteristic

Adopt famous-brand high reliability DFB laser.

Adopt the technical of digital automatic frequency power, make CSO, CTB and C/N to the best , stability amount of output level.

Advanced technology of multi-point frequency pre-distortion, coordinated with GaAs, make better index of CTB and CSO.

Set with integrity automatic micro computer minor circuit and all kinds of situation of optical power output and laser.

Special Notice

The performance parameters of this manual according to GY/T143-2000 < Network Entry Technical Requirements and Measurements Method of CATV laser Optical Transmitter and Receiver >

Testing Environment

Below part of optical receiver: 10km standard optical fiber, no source of optical attenuator and the testing circuit of standard optical transmitter. Set with 59 PAL-D analog TV channel signal at range of 47MHz~550MHz in the fix index loss of circuit. Transmit 640QAM concoct digital TV signal at rang of 550MHz~862MHz, the electricity level (8 MHz bandwidth) digital signal is lower 10dB than analog signal of carrier electricity level; the input of optical receiver is 1dBm, output level of RF is 96dBuV with lean beam of 9dB output, measure C/ CTB, C/ CSO, C/ N.

TS-1003 forward Optical Receive Module  Performance Characteristic

Adopt PHILIPS, PHOTON or E-O high-reliability of the PIN optical filter and import PHILIPS or MOTOROLA low-noisy pull-push amplifier module.

Adopt high-capability power doubler amplifier module or GaAs, make sure the good index of circuit, could apply the good source of RF signal for diode network transmission.
