Alloptic supports complete video transport for both RF video and IPTV. The Alloptic system supports RF video on a single optical fiber. Both downstream and upstream video is carried on wavelengths separate from the data and voice traffic. Separation of RF video and IP on the fiber ensures that IP bandwidth - whether for video, voice, or data - is unaffected by RF video. Thus, hundreds of channels of analog and digital video can run over the same network while leaving a full 1Gbps per PON for mission-critical data, voice, and video services.

For IP video services, the ability to provision up to 100Mbps per port is more than enough bandwidth for multiple channels of HDTV. Bandwidth efficiency is maintained as well. By supporting multicast transmission with IGMP snooping and proxy implemented at both the ONT and OLT, single-copy broadcast (SCB) is achieved at every point in the access network. Other technologies using unicasting send a unique stream of IP video for every set top box. Alloptic's system sends only one stream per channel through the network. For example, 25 set top boxes watching the same channel being unicast means 25 unique video streams. Those same 25 set top boxes watching the same channel over an Alloptic system with multicasting require on 1 unique video stream. From a bandwidth perspective, 25 HDTV channels @ 10Mbps/ch with unicasting = 250Mbps; Alloptic with multicasting uses only 10Mbps of valuable network bandwidth.
