1550nm Fiber Optical Transmitter OPT-1550E-S 1550nm
External Modulation Optical Transmitter

Product Overview

OPT-1550E-S Series External modulation optical transmitter is a Standard type of high- performance 1550nm external modulation optical transmitter. It is especially designed for small or middle-size TV stations, CNR ≥51.50dB when tested in 59CH PAL/D, SBS set at 18dBm, point to point 50km fiber.

Mounted in standard 1U, 19’’ chassis, the output signal spectral lines is narrow, more advantages in the long- distance transmission. Key components adopt DFB low-noise, narrow line-width, continuous-wave lasers with thermoelectric cooling device made in JDSU, Fujitsu, MITSUBISHI and AVANEX CATV high linearity external modulator. Because of the international brand adoption of key components and our company system optimization control technology, SMNP network control technology, the machine's technical performance indicators fully measure up the standard of similar imported equipment , It can provide high-quality images, digital or compressed digital signal long-distance transmission for cable television and telephone communications.

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

In ensuring the high performance system CSO, the phase modulation technology of external modulator maximize the optical power into the fiber in order to obtain long- distance transmission, and the field adjustable SBS threshold 13,16,18, may apply a different network transmission.

The 19 "1U standard rack, built-in high-performance dual switching power supply, 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, and the panel LCD window displays the operating parameters.

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