JPTXEA-0415

1550nm high power internally modulated optical transmitter is mainly used for high power output and wide range coverage of secondary service area (sub front end). There is 1550nm Erbium-doped Fiber Amplifier (EDFA) added on the basis of internally modulated optical transmitter. It adopts high linear DFB laser, with built-in pre-distortion compensation and AGC, APC, ATC control, which greatly improves the comprehensive index of the system.

1550nm high power internally modulated optical transmitter is the core device for the construction of CATV secondary transmission networks. It is mainly used for value-added services such as TV image signal, digital TV signal, telephone signal and data (or compressed data) signal. It is a high-quality but low-cost solution to realize triple play and FTTx transmission systems.

Features of JPTXEA-0415

  • It adopts original low chirp and high linearity DFB laser as signal source.

  • It adopts world’s top brand pump laser and erbium-doped fiber, which ensure stable operating of the device.

  • The perfect pre-distortion circuit ensures the perfect performance of CTB and CSO in high standard CNR value.

  • Fully automatic case temperature control, which ensure long operating life of the device.

  • Built -in dual standby power supply, hot plug and automatic switch supported.

  • The working parameters of the whole machine are controlled by microprocessor and the LCD status display on the front panel has many functions such as laser status monitoring, parameter display, fault alarm, network management, etc.; once the working parameters of the laser deviate from the allowed range set by the software, the system will alarm promptly.

  • Standard RJ45 interface provided, supporting remote network management of SNMP and WEB.
