Product Description

CATV Fiber Optic 1550nm Directed Modulation Optical Transmitter
(FWT-1550DT-10)

Product description:

FWT-1550DT series of products adopt the high linearity, optical isolation, the DFB, thermoelectric cooling DFB laser produced by XT, ORTEL ,AOI and other world-renowned semiconductor companies. It can provide high-quality images, digital or compressed digital signal long-distance transmission for cable television and telephone communications. Built-in RF driver amplifier and control circuitry to ensure the machine's CNR, CTB, CSO target. Comprehensive and reliable optical circuits and laser output power stability Temperature stability of thermoelectric cooler control circuit to ensure optimal machine performance and long-life laser stability. Laser is the most expensive machine components, machines equipped with microprocessors. The microprocessor software to monitor the working state lasers, operating parameters from the panel LCD display. Once the laser operating parameters deviate from the permissible range set by the software, the microprocessor will automatically turn-off laser power. Flashing yellow light prompts alarm panel LCD prompts cause of the malfunction (non-human factors that can not be damaged laser). RF pre-distortion technology, ensuring the case of CSO-performance system for maximum CNR. In addition, the use of 19 "1U standard rack, high-performance Plug-in type dual Power can be 85 ∽ 265Vac City Network voltage work.

Feature:

High quality: original system optimization control technology and RF pre-distortion technology ensure that the system can acquire the maximum CTB, CSO, and SBS targets in the case of excellent performance CNR .

Reliability: The 19 "1U standard rack, high-performance Plug-in type dual Power,it can work in the backup at 85 ∽ 265Vac City Network Voltage, MS-level automatic switching; chassis cooling automatic temperature control.

Intuitive: The laser is the most expensive machine components, machine equipped with microprocessor monitors the working state of the laser, the panel LCD window displays the operating parameters. Once the laser operating parameters deviate from the permissible range set by the software, micro-processing will automatically turn off laser power, yellow light goes on to warn, the panel LCD prompts the cause of troubles.

Network type: Select All-piece status monitoring transponder guarantee to meet the national standard and be compatible with the SCTE HMS standard, it enable network management monitoring capabilities.
