Multicast Optical Fronthaul for Broadcast and Edge Computing

Efficiently distributing high-bandwidth video broadcast and edge computing data payloads using optical splitters and photonic multicast transport.

The Inefficiency of Point-to-Point Fronthaul for Broadcast Content

Streaming live sports events, emergency public broadcasts, or popular software updates over point-to-point fronthaul links requires duplicating packets across every individual radio unit, saturating transport bandwidth. Optical RAN solves this through native photonic multicast.

Photonic Point-to-Multipoint Wavelength Broadcasting

Leveraging passive optical splitters and broadcast WDM filters, Optical RAN can replicate identical downstream optical signals to dozens of distributed radio units simultaneously without consuming extra fiber bandwidth or processing power.

Integrating Multicast with 5G MBMS and Edge Caching

Optical multicast feeds seamlessly into 5G Multimedia Broadcast Multicast Services (MBMS) and edge caching servers co-located at optical aggregation nodes, delivering high-definition video content directly to baseband units for local radio transmission.

Bandwidth Savings for High-Density Stadiums and Venues

In dense deployment scenarios like stadiums or concert venues, optical multicast reduces fronthaul transport bandwidth consumption by up to 80% during major live broadcast events.
