CATV AGC WDM filter FTTH optical receiver
FTTH type optical receiver is a home-based optical receiver cater to the ultimate goal of development of optical access for FTTH (FTTH) network, analog or digital signal can be realized. The equipment uses low-power optical detector, GaAs and optical control AGC technology to meet the needs of FTTH CATV reception. Variety of functional products in the application is slightly different.
FTTH type optical receiver OR19 with AGC, plug-in photocell. OR19WD with WDM and AGC.
♦ Plastic case with good heat dispersion.
♦ Adopts GaAs module as RF amplifying module, the optical receiving range for digital signal can reach-22dBm,and -10dBm for analog signal.
♦ AGC control range can be customized.
♦ Low consumption design and total consumption ≤4w, high reliable switching power supply with optical inspection circuit.
♦ SC/APC or FC/APC optical connector.
♦ Built-in WDM,single-fiber to the home (1490/1310/1550nm) triple-play application can be realized.
♦ Built-in isolator can split the two optical waves (1490nm and 1310nm)
♦ Anti-high-frequency surge device to protect the GaAs amplifier tube.
♦ Multi-stage lightning protection devices (TVS transient suppression diodes), lightning protection system closely to ensure the safe operation of equipment.
♦ Realize the 5V input port feeding way of power supply.
