1550nm Erbium-Doped Fiber Amplifier (Indoor With RF Input)

 1550nm Erbium-Doped Fiber Amplifier (Indoor With RF Input)

  •  1550nm Erbium-Doped Fiber Amplifier (Indoor With RF Input)
Model No.:  EDFA1550/RF

Product Description

Features
EDFA working wavelength cover with whole C-Band(1528~1564nm)

EDFA adopt LA, low input, ensure main road optical input is more than or equal to 0dBm, all have favorable system CNR
Three kinds EDFA gain spectrum flatness optional:

SCH single channel

F10 gain flatness, is less than or equal to plus or minus 0.5dB

F20 gain flatness is less than or equal to plus or minus 1.0dB

DMTX adopt high linearity, with cooling DFB laser, pre-distortion compensation

DMTX option ITU wavelength, wavelength adjustable

DMTX output optical power through the built-in VOA, from the front panel adjustments and settings. To avoid the interferes caused by mismatching of the optical output power between TX and main line signal from outside

Laser APC, ACC, ATC control

  Standard RS232 communication interface, prefect SNMP network management function

Excellent P/P ratio.

Description
EDFA1550/RF series is the narrow-band multiplexing EDFA which suitable with CATV application. This EDFA build-in one unit 1550nm direct modulated CATV transmitter used in inter cutting local VAD service. Build-in WDM multiplexing TX optical signal and External input optical signal of the main road then enter EDFA amplification, to server the local users. In order to avoid TX output optical power and the external input optical power does not fit the main road interfere with each other, the output power of the TX through the build-in VOA, from front panel adjust and set. The whole unit is concision, install and debug convenient. Providing high-quality, low-cost solution for all-optical relay 1550nm optical CATV systems, second-grade service area or administration village inter cut local VAD service.

Applications
CATV value-add service

Second-grade service area (substation, sub head-end), inter cut local program, IP/QAM, VOD.

Villages and towns, administration village inter cut local individuation program and frequency modulation (FM)
