Huatai HA5200 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.
HA5200 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.
Huatai is the famous manufacturer of EDFA. HA5200 adopts the world's top class pump laser and America OFS erbium-doped optical fiber. Perfect APC, ACC and ATC control, excellent design in the ventilation and heat-dissipation ensure the long life and high reliable work of pump laser. RS232 and RJ45 offer serial commutate ion and SNMP network management port. The LCD at the front panel offers the work index of all equipment and warning alarm. Optical loss and laser closing automatically provide safe protect of the laser. All the optical port can be installed in the front panel (also can be in the back panel if customers specify).
Huatai product, for its high quality, high reliable and high cost performance, is the ideal choice of the system integration and system operation.
1540~1563nm operating wavelength
Extra low noise index
