Product Description

Brief Description

SR2020AW, with an operating bandwidth of 47~1000MHz, is a low-power, high-performance, cost-effective triple play, FTTH CATV optical receiver, Whether used in analog television or digital television. Products with high sensitivity optical receiver tube and special low noise matching circuit. Receiving at high optical power can be adjusted by PAD level, played limiting output, so SR2020AW within a large dynamic range of the received optical power of +2 dBm ~-21dBm, has excellent characteristics.
Triple play, fiber to the home, using the SR2020AW can save a lot of optical fiber amplifier power resources. For operators, can greatly reduce the cost of building the network.

 

Functional Features

1. Extra-low noise(3.8% modulate, -10dBm receive, CNR ≥ 45.3dB)
2. Wide dynamic receiving optical power range: within Pin=-16, MER≥36.1dB
3. Applicable GPON, EPON, compatible with any FTTx PON technology
4. Can save a large number of optical power resources, and greatly reduce the network configuration cost
5. Within 47~1000MHz bandwidth, all with excellent flatness features ( FL≤±0.75dB )
6. Metal case, offer a safeguard for optic electronic sensitive devices
7. High output level, which can be used by many users
8. Low power consumption, high performance, high-cost performance

 

NOTE

1. The power adapter for this equipment: Input 110/220V; Output DC 12V(0.6A).
2. Keep the optical connector clean, the bad link will cause too low an RF output level.
3. Should not adjust by themselves, to avoid device damage.
