The LR91 W 1550 is a compact receiver for CATV distribution networks and RF overlay. The integrated, very narrow-band, WDM filter allows the out-coupling of the xPON wavelengths, which are additionally connected to the CATV. It has a high output level up to 100 dBμV in the frequency range up to 1 GHz.
- Compact node for CATV downstream reception and RF Overlay
- Extremely low noise optical receiver
- High RF output level, switchable: 80 dBμV (flat) or 100 dBμV (6 dB slope) for 4% OMI
- Manual adjustment of optical level compensation for maximum flexibility
- Test port for RF output signal
- Monitoring LED and DC test port for optical input power
- PON pass-through port for CATV overlay signals in single-fiber FTTx networks
