HZY-E1550S-XX series standard version external modulator transmitter 20~50KM

HZY-E1550S-XX adopting the LiNbO3 external modulator specially developed for CATV signal modulation, and independently developed and designed dual microwave source optimization control technology. 47 ~ 862MHz bandwidth, CNR ≥ 51dB, CTB ≤ -65dB, CSO ≤ -65dB, SBS: 13, 16, 18, 19 dBm adjustable, which can meet the high-quality transmission of video, audio and data in CATV networks. Equipped with SNMP network management, 1 + 1 power supply backup. HZY-E1550S-XX series standard 1550nm external modulation optical transmitter, with excellent performance-price ratio, suitable for FTTH triple play CATV from headend to end user.

◆Top quality: The original dual microwave source innovation technology and RF predistortion technology ensure the system has the perfect CTB, CSO and SBS indexes when CNR≥51dB.

◆Flexibility: The phase modulation technology of the external modulator maximizes the optical power of the fiber to obtain long-haul transmission while ensuring the excellent CSO performance of the system, and the SBS threshold is adjustable: 13,16,18,19 dBm; AGC / MGC mode selectable at site, OMI can be adjustable, suitable for different network transmissions.

◆Reliability: 19” 1U standard rack, built-in high-performance 1 + 1 hot backup power supply, which can work at 86 ~ 265Vac city network. MS automatic switching, and chassis temperature automatic control.

◆Excellent performance-price ratio: suitable for FTTH triple play CATV from headend to end user.

◆Intuitive: The external modulator and laser are the most expensive components of the device. The built-in microprocessor monitors the external modulator and laser working status, and the working parameters are displayed on LCD.

◆Network management type: SNMP network management, can realize the network management WEB monitoring function.
