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
Laser APC, ACC, ATC control
Standard RS232 communication interface, prefect SNMP network management function
Excellent P/P ratio.
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.
