LX 25 X XDXX RFoG Upstream Receiver
Category : Optopus optical receivers 19-inch
Upgrading your network infrastructures to OBI-free (Optical Beat Interference) RFoG networks with this active upstream receiver. Use up to 32 output ports (or cascade them to reach higher port numbers) and eliminate issues instantly with the dedicated upstream receivers. Each of these ports provides an input power measurement in real time and can be shut off if necessary (testing purposes or subscriber service shutdown). That's why the LX 25 enables network providers to heal existing OBI-infected RFoG networks without any need to swap existing end user equipment. The solution will work with any upstream wavelength and laser mode. OPTOPUS and its OBI-free RFoG technology offer network providers a complete future-proof concept, while opening the doors for new FTTx deployments.
- Converts existing RFoG networks to OBI free solutions without exchange of fiber nodes
- Remote optical input power reading and switch off functionality per port via SNMP and WEB
- Two BC input ports
- Electrical upstream test port
- Local or remote powered version available
- All connectors on the front
