Description
Applications
HY-21-R51 optical receiver is specifically designed for CATV FTTH network. Its main feature is low power consumption, small Volume and high reliability. Adopting aluminum alloy shell. It is an ideal product to build FTTH CATV network.Built-in WDM，can be satisfied with one optical fiber transmission television signals(CATV)+ broadband data（PON），Separate receiving 1550 – nm wavelength section of CATV signals and output PON signals (1490/1310 nm)。
Performance characteristics
- Using high quality E -O photoelectric conversion and GaAs amplifier integrated optical receiving module.
- Built-in WDM can realize single-fiber home (1490/1310/1550nm) tri-network convergence applications.
- Built-in optical isolator, input to achieve 1490/1310nm isolation.
- SC/APC or FC/APC or custom optical connectors, metric or imperial RF interfaces.
- RF channel all GaAs low noise amplifier device.
- High quality aluminum alloy shell, good anti-interference and shielding.
- Output voltage: no power supply
