45~2600MHz catv + L-band Satellite Optical Receiver Optical Node
FWR-2620 , CATV + Satellite Optical Receiver , 45~2600MHz.
Product overview
1. FWR-2620 Series CATV and Satellite middle channel optical receiver is working in 40~2600MHz bandwidth.
2. It is an embodiment of high-tech in CATV and L-band satellite fiber linking products.
3. Offer a lowest cost case for network operator. 4. Due to the key elements of the units using international bands and system optimizing control technology,
the technology index reach the congeneric import products completely.
5. Supply long distance transmission of advanced image, digital and compress digital single.
Features
1. High quality: due to adopt international band MMIC in low noise and high action, optimize CN. CTB. CSO. IMD. 2. Flexibility: the receiver can output by one or double ports. Wall mounting type indoor, few space occupation.3. Reliability: connected with high capacity witch power supply, working in 85~265Vac Voltage. 4. Intuitive: optical power set in the surface of units, the input optical power can be distinguish promptly.
