1550nm Optical Transmitter

描述

Descriptions:

LT1500 Fiber Optic Transmitterwith DFB laser improved from 08LTxx, increase hot plug-in dual  power and optical point. Optical signal of signal source can directly enter into optical interface which not only  reduce trouble for connecting optical receiver, but also main signal enters optical point, program made by user entering RF point. Accordingly, program by user is modulated to optical signal which can cater to many demands of user.

LT1500 Fiber optical transmitter is mainly applied for 25km (digital signal 35km) distribution network and amplifying. Disadvantage is that it is bad for point to point transmission, Index of it is not good for 1310nm optical transmitter

Features:

• The use of high-performance DFB lasers of international famous brands has narrow spectral lines, good linearity, and high output power.
• The advanced multi-frequency RF predistortion technology uses RF power automatic processing technology to automatically optimize the drive level so that the C/CTB, C/CSO, and C/N specifications are always at optimal values.
• The 32-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 optimal laser performance.
• 47-862MHz (1000Mhz can be customized) operating bandwidth.
• The dual-module structure is reserved to increase the functions of light emitting, EDFA, light collection, RF switch, and other functions.
• Modular structure, easy to expand the function of equipment and maintenance.
• 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 220V & 110V & 48V optional.
