The LR93 x xxxx is a DOCSIS 3.1 upstream frequency compliant RFoG transceiver for use in Passive Optical Networks (PON). For an easy migration towards DOCSIS 3.1 Upstream frequency splits, the diplex filters are pluggable. An LED displays whether the optical input power is within the target range (green) or outside (red).Within that range, the included Automatic Level Control (ALC) provides a constant RF output level, which is either 80 dBµV flat or 97 dBµV at 5 dB slope. The return path transmitter operates in "Burst Mode" which activates the optical transmitter only when data is sent. In the remaining time, the transmission power remains at minimum level, to connect many nodes to the same upstream receiver without noise accumulation.
- Compact node for RFoG-systems
- DFB laser for upstream transmission with high signal quality
- According to SCTE ISP SP 910
- Extremly low-noise receiver
- Optical ALC for automatic control of downstream output level
- Optimiized Burst-Switching
- Pluggable RF diplexers enable step-by-step migration towards DOCSIS 3.1 upstream frequencies
