CATV Line EDFA Fiber Optic Amplifier
Overview:
Optostar OP-EDFA-5200 series C-Band line-amplifier EDFA (also knows as relay EDFA), is designed for the application of single channel or 1~8
continuous ribbon channels (ITU wavelength). Fiber CATV system operates generally in single wavelength
that has no strict requirement on gain flatness. In order to reduce the effect of CNR deterioration caused by
EDFA, input power should be as high as possible to make EDFA operate in saturated output power. The
typical value of input power is >+3dBm.
OP-EDFA-5200 relay EDFA (Low-Input type) adopts noise filtration technology in the optic path, and can filter spontaneous radiation effectively.
When the input is 0dBm, its CNR can reach 49.5dBm, applied in sub head-end and line relay.
Main features:
◆1540~1563nm operating bandwidth
◆Extra low noise index
◆High output, high reliability
◆APC, ACC, ATC controlled selection (OP-EDFA-5200/P)
◆Powerful RS232 supervisory instruction
◆Three exterior option: 1U (19” stander), 3D (12.4”, 3U, Desk-type) and modulator
◆1U and 3D exterior, offering status appearance and diagnosing fault with LCD, standard RS232
communication interface, SNMP network management function
◆Application of 3D models to adapt to laboratory
◆Excellent P/P ratio
Main application
◆In the original 1550nm optical system, all 1310nm optical transmitters can be cancelled in the second
grade service area with 0dBm receiving power. Instead, OPED5200 can be adopted to carry out full optic
relay and then achieve large acreage cover of all the service
area.
◆Over-long trunk with low-input
◆AM CATV
◆Digital CATV
◆DBS & MMDS
◆FTTx PON
◆Laboratory application
