HZY-E1550A-XX series advanced version external modulator transmitter 50~150KM

HZY-E1550A-XX adopting the LiNbO3 external modulator specially developed and produced by USA Oclaro for CATV signal modulation, and independently developed and designed dual microwave source optimization control technology, which achieves transmission of more than 120KM, CNR≥53dB, CTB≤-65dB, CSO≤-65dB, 47 ~ 862 MHz, SBS: 13-19dBm continuous adjustable. Equipped with SNMP network management, 1 + 1 power supply backup, and chassis temperature automatic control. Tunable wavelength range: 1528.77 ~ 1563.86nm, adjustable width: ＞35nm. The light source of the device adopts narrow line width, Typ. = 0.65 MHz, low noise, continuous wave DFB laser, which is propitious to reduce the influence of dispersion.
The HZY-E1550A-XX type includes all available wavelengths in the C-band (the effective range of the CATV wavelength is 1540 to 1563nm). Users can quickly and accurately implement the selection and conversion of wavelengths according to the needs of the network. Convenient in the application of DWDM system, backbone network and metropolitan area network are limited to the number of fiber cores during long-haul transmission. DWDM technology can make full use of the existing fiber optic resources, ultra-large capacity for networking, and has high flexibility, economy and high reliability.

◆High quality: the original dual microwave innovative new technology, RF predistortion technology insure in the situation of quality CNR≥53dB, system can get largest CTB.CSO. SBS index.

◆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 continuous adjustable: 13-19 dBm; OMI, ITU wavelength adjustable, AGC/MGC selectable，suitable for different network transmissions.

◆High wavelength accuracy: wavelength (frequency) locking accuracy (± 0.02nm), wavelength stability ± 0.01nm.

◆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.

◆Power plug-in type: The aluminum-type plug-in switching power supply can work at 86 ~ 265Vac city voltage, and can also be easily replaced by -48Vdc DC power supply, and 1 + 1 power backup, supports hot-pluggable.
