1550nm optical transmitter

Description

Both the laser and the external modulator are imported original quality products made in US or Japan. The predistortion circuit, SBS restriction circuit, and SBS valve values adjustable among *3, *5 and *6dB can satisfy different network demands. In addition, the CAT, APC, and radio frequency gain control circuit can enable the laser to work stably for a long term. The unit is supplied with a special microprocessor, which provides diverse functions including laser state monitor, digital indication, fault alarm, and network management etc. The unit provides RJ*5 and RJ***2 standard interfaces for network management and monitor. It can be widely applied in the transmission of CATV, telephone, digital and compressed digital data.
