Product overview
OPT-1550E-W Series is wavelength-adjustable type of high-performance 1550nm external modulation optical transmitter. It is mainly applied in WDM system, fiber access, optical modulation , network upgrade and extension. Max adjustable range +/-1.6nm, divided into 64 steps, stepping 0.05nm each. Mounted in standard 1U, 19’’ chassis, Adopting imported low noise DFB laser as signal source, and high-linearity LiNb03 external modulator as signal modulation , It can provide high-quality images, digital or compressed digital signal long-distance transmission for cable television and telephone communications.
 
Features
(1) 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.
 
(2) Flexibility: 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.
 
(3) Reliability: 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.
 
(4) 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.
 
(5) 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.

Note:
1) In the condition of stipulated link-loss, configured in 59 PAL-D analog television channel signals within 550MHz frequency, in the range of 550MHz ~ 750 (862) MHz frequency transmit digital modulation signals, digital modulation signal level ( in 8MHz bandwidth) is 10dB lower than the analog signal carrier level, when the optical input power is 0dBm, you can measure the carrier combination triple beat ratio (C / CTB), carrier combination of second-order beat ratio (C / CSO) and the carrier to noise ratio (C/CNR)
