Optical Relay Station
Overview:MICORT860Y series field 1310nm optical relay station is specially developed for 1310nm optical relay transmission. It provides economic and practical solution for relay transmission in the 1310nm optical fiber network project. This product is mainly used in optical fiber transmission of CATV network. Moreover, it adapts to various operating environment.
●Adopts high performance photoelectric conversion module, RF amplifier module and DFB laser.
●Excellent pre-distortion circuit to improve C/CTB and C/CSO.
●AGC RF control circuit ensures the constancy of the laser’s modulation depth.
●ATC and APC ensure the best operating status of the laser.
●Slow-start circuit and RF over-protection circuit ensure the laser will not be damaged.
●Perfect microprocessor automatic monitoring circuitry can monitor the operating status real-timely and precisely
●Front panel display status and alarm.
●Water-proof die-cast aluminum housing, convenient for installation and test.
●Highly reliable double-switching power supply and lightning-proof system.
CNR,CSO,CTB should be tested under the following conditions : form the test link with standard optical receiver and standard optical fiber configure 59 PAL-D analogue video channel signals in the frequency range of 550MHz; transmit digital modulated signal in the frequency range of 550～750（862）MHz; the level of digital modulated signal（within 8Mhz bandwidth）is 10dB lower than carrier level of analogue signal.
