SK-OR-860LH-I Outdoor optical receiver
Features
Overview
SK-OR-860LH-Ⅰ series field optical receiver is a kind of NEW CATV network products. It adopts the combination of module amplification circuit and GaAs MMIC amplification circuit to optimize the line design to make the machine output with higher performance index when input is in -8～+2dBm. Output designed with adjustable attenuator and equalizer can make CATV network subject very convenient to debug. At mean time to transmit digital and analogue signal, it is the priority in current HFC, EPON network system construction.
Features
● 1310nm and 1550nm dual-window receiving.
● 8-section LED displays input optical power.
● Output designed with adjustable attenuator and equalizer, easy to debug.
● Output plug-in one-way tap or two-way splitter, easy to replace and operate.
● High-reliable switching power supply, small temperature rise, high conversion efficiency, wide voltage range.
● Each port is equipped AC60V LED indicator light, easy to operate.
● Perfect surge suppression circuitry, which is effectively to prevent shock and lightning surge.
● Equipped AC60V sole power supply port, easy to operate.
● High-quality die-casting aluminum housing, dust-proof, water-proof, shield and good heating performance, convenient to install.
