Sell CATV Line-Amplifier EDFA

Description

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, input power should be as high as possible to make EDFA operate in saturated output power. The typical value of input 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 input 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

• ***0~***3nm operating
• bandwidth Extra low noise index
• High output, high reliability
• APC, ACC, ATC controlled selection (HA***0/P)
• Powerful RS**2 supervisory instruction
• Three exterior option: 1U (*9' stander), 3D (*2.4', 3U, Desk-type) and modulator
• 1U and 3D exterior, offering status appearance and diagnosing fault with LCD, standard RS**2 communication interface, SNMP network management function
• Application of 3D models to adapt to laboratory
• Excellent P/P ratio

Main application

• In the original ***0nm optical system, all ***0nm optical transmitters can be cancelled in the second grade service area with 0dBm receiving power. Instead, HA***0 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
