Description
Product Summary
HY-21-R03 optical receiver is an outdoor 4 outputs waterproofing receiver. It is mainly used in the building, community or village with concentrated users and high level multi outputs distribution network. Also suitable to be used in the place where it is not convenient to take the electricity and single equipment drives many users. It can work together with ONU or EOC to realize the network convergence. HY-21-R03 optical receiver adopts MMIC as the pre-stage amplification and hybrid module in the backward stage. Adjustable attenuation and equilibrium makes the debugging extremely convenient. The users also can choose the module combination according to their actual requirements. Optimized circuit design guarantees the perfect performance and is the ideal model for CATV network.
Performance Characteristics
- Adopt waterproof aluminum shell and the waterproof level could reach to IP65 grade.
- Double shield panel that can ensure the excellent EMC index.
- Advanced GaAs low noise amplified circuit increases the receiving sensitivity.
- AGC control range +2~-7dBm, output level unchanged. CTB, CSO basically unchanged.
- Ten pieces luminescent can show more accurate optical power. The branch and distribution can be exchanged.
- AC – 60v has independent power supply port.
- With internal button fuse box, convenient and quick to chang
- Adopt anti surge lighting circuit that can protect he power supply effective
- With external test port that can test without opening the housing. International general SNM

Note 3: Under the fixed link loss, 550 MHz has 59 PAL – D channel analog TV signals. Among 550 MHZ to 862 MHz, every 2 MHZ band transfer the digital modulation signals. It is tested when the digital modulation signal level is 10dBm lower than analog modulation signal level and the optical receiver input optical power is -1dBm. Test results will differ according to the different hybrid module. Pls refer to the user manual for details.
