SK-OR-860F2 FTTB optical receiver
Features
Overview
SK-OR-860F2 FTTB optical receiver is a kind of product which is designed for CATV network FTTB application. With small and compact construction, easily to install; Featured with AGC function to make output level keep constant and have higher performance index when input optical power is -8~+1dBm. It also can realize to control output level and slope of the equipment through network management system remotely and completely, to make CATV network project debugging very conveniently. At meanwhile this product can transmit digital and analogue signal. It is the main product in present FTTB network system construction.
Features
● 1310nm and 1550nm dual-window receiving;
● 1000MHz RF output bandwidth;
● LED numeral tube displays each working parameter real timely (optical power, attenuation, equalization, output level, voltage, temperature);
● Pressing key to adjust RF output level and slope;
● Two ports output, with -20dBm testing port, easy to debug
● Optical control AGC function, to make output level stable when input optical power is in -8~+1dBm.
●Network management complies with international GB/T20030-2005 ‘HFC network device management system standard;
● Perfect surge suppression circuit to prevent surge stroke and lightning stroke efficiently;
● Low consumption design, the whole machine consumption is less than 6.5W;
● Good quality small aluminum shell, featured with dustproof, good shield and heat radiation, easy to install.
