CATVFTTH-OR19 Series Optical Receiver
Features
1. RF channel full GaAs low noise amplifier circuit. The digital signal satisfies -18dBm reception and the analog signal satisfies -10dBm reception.
2. With light input AGC function (AGC range -3~-12dBm).
3. Anti-frequency surge protection device, GaAs amplification chip.
4. Low-power design, high-efficiency switching power supply ensures high reliabilityand high stability of the power supply. The overall power consumption is less than 2W, with optical detection circuit.
5. Can be built-in WDM to realize single-fiber home (1490/1310/1550nm) tri-network convergence application.
6. FC/APC or SC/APCTM or FC/PC or SC/PC, metric or imperial RF interface(customizable according to customer requirements).
7. Multi-stage lightning protection devices (TVS transient suppression diodes) and lightning protection systems ensure the safe operation of the equipment.
8. Output power supply can be achieved.
Applications
The FTTH-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 needs of fiber-to-the-home CATV reception. Among them WS-FTTH-OR19 with WDM as the main push product, is a home-made equipment that is tailored to realize triple play.
