Outdoor type Four Output Optical Receiver

Description

The 4 Port CATV Outdoor Optical Receiver is designed to deliver stable, high-level RF signal distribution in FTTH, FTTB, HFC, community broadband, and village CATV networks. Featuring four RF outputs, automatic gain control (AGC), and an IP65 waterproof aluminum housing, this 4 output receiver ensures reliable operation even in harsh outdoor environments while maintaining consistent signal quality for multiple subscribers.

The rugged outdoor design makes it an ideal solution for multi-dwelling buildings, residential communities, rural broadband projects, and locations where power resources are limited. Support for ONU or EOC integration, Outdoor Optical Receiver enables efficient Triple Play service delivery,including CATV, broadband Internet, and IPTV. The combination of high output capability, lightning protection, network management support, and flexible output configuration makes this optical receiver a dependable choice for modern CATV distribution networks.

1. Outdoor Optical Receiver Applications

The four-way output optical receiver is a field rain-proof receiver. It is suitable for users with concentrated buildings or communities or villages. It is suitable for multi-port high-level output distribution network. It is suitablefor areas where power is not convenient, single unit with multiple users. Can be used with ONU or EOC to achieve triple play.

The front stage of the four-way output optical receiver is amplified by a full GaAs MMIC, and the latter stage is a GaAs module amplifier. The adjustable attenuation and equalization are very convenient for construction. Users can also select more targeted high-quality modules according to actual needs. The optimized circuit design makes the machine achieve high performance index, which is the ideal model for building CATV network.

3. Technical Parameters

Note 1: 59 PAL-D analog TV channel signals are configured at 550MHz and 550MHz-862MHz transmits full-band digitally modulated signals every 2MHz at the specified link loss. The digitally modulated signal level is 10 dB lower than the analog modulated signal level and tested when the optical receiver input optical power is -1 dBm. The test results will be different according to the different amplification modules of the optical receiver configuration.
