Product Description:

Spacecom SPC***0 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, power should be as high as possible to make EDFA operate in saturated output power. The typical value of power is >*3dBm. SPC***0 relay EDFA (Low-Input type) adopts noise filtration technology in the optic path, and can filter spontaneous radiation effectively. When the is 0dBm, its CNR can reach *9.5dBm, applied in sub head-end and line relay.

Spacecom is the famous manufacturer of EDFA. SPC***0 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. RS**2 and RJ*5 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).

Spacecom product, for its high quality, high reliable and high cost performance, is the ideal choice of the system integration and system operation.

Product features
