OR19 Series Optical Receiver Instructions
I.Applications
The OR19 optical receiver is a home optical receiver with optical fiber access as its ultimate goal. It is suitable for FTTH (Fiber to the Home) network optical fiber subscriber access terminals, enabling analog or digital signals to enter the home. The machine uses low-power photodetectors, GaAs and optical AGC technology to meet the fiber-to-the-home CATV reception needs. Among them OR19 is based on WDM as the main push product, and it is a home-based equipment tailored to realize triple play.
II.the performance characteristics
- RF channel full GaAs low noise amplifier circuit. Digital signal can satisfy -18dBm reception, analog signal minimum meet -10dBm reception;
- With light input AGC (AGC range can be customized according to the user);
- Anti-high frequency surge device protection, GaAs amplification chip;
- Low-power design, using high-efficiency switching power supply to ensure high reliability and high stability of the power supply. The overall power consumption is less than 2W, with a light detection circuit;
- FC/APC or SC/APCTM or FC/PC or SC/PC, metric or imperial RF interface (customizable according to customer requirements);
- Multi-stage lightning protection device (TVS transient suppression diode), lightning protection system is tight, to ensure the safe operation of the equipment;
- It can realize the power supply mode of output feed.
