Fiber optic catv 1550 transmitter 25km dual fiber transmitter

Product Description

WS-LT***0 series direct-modulation optical transmitter is a ***0/***0nm laser transmission device independently developed by WSEE and has complete independent intellectual property rights. It has high performance, high reliability and excellent performance-cost ratio and can be widely used in various applications. Long-distance digital and analog signal communication applications include secondary CATV trunk lines and distribution networks, CWDM/DWDM systems, fiber optic sensing, and security monitoring systems.

The use of high-performance DFB lasers of international famous brands has narrow spectral lines, good linearity, and high output power.
Advanced multi-frequency RF predistortion technology. The driver circuit adopts RF power automatic processing technology, which can automatically optimize the driving level so that the C/CTB, C/CSO and C/N indicators are always at optimal values.
**-bit ARM processor can efficiently coordinate the working status of each module and accurately monitor and control each operating parameter.
Laser temperature stabilization circuit (ATC) and optical power output stabilization circuit (APC) ensure the best working performance of the laser.
*****2MHz (***0Mhz can be customized) operating bandwidth.
The dual-module structure is reserved, and functions such as light emitting, EDFA, light collection, and RF switch can be added.
Modular structure facilitates function expansion and maintenance of equipment;
Standard network management interface, in line with SNMP network management protocol;
The power supply can realize dual power hot backup, snap-type fixed, one-touch pull. Easy to operate, firmly fixed. Voltage **0V & **0V & *8V optional.
