Examine how physical layer splitting and compression algorithms overcome bandwidth constraints across optical fronthaul networks.
The 7.2x Functional Split Standard
The 7.2x split divides Lower Layer 1 (FFT, resource mapping, beamforming in the O-RU) from Upper Layer 1 (channel coding and modulation in the O-DU), optimizing hardware complexity while preserving software control. [Source: IEEE 802.1CM Time-Sensitive Networking for Fronthaul]
Sub-THz Bandwidth Explosion and Compression Mandates
Operating in sub-THz bands with gigahertz of bandwidth generates terabits of uncompressed IQ data. Advanced bit-level compression algorithms and dynamic eCPRI framing reduce optical transport bandwidth requirements by 80%. [Source: O-RAN Alliance Open Fronthaul Specification]
Time-Sensitive Networking (TSN) for Low-Latency Transport
Precision packet timing and jitter control are essential over open fronthaul links. IEEE 802.1CM TSN standards ensure deterministic packet arrival times for mission-critical radio signaling.
