简要描述：
Baseband UBBPg2a(03058707 / 03058705)Buy the Huawei UBBPg2a (03058707) — a high-capacity universal baseband processing unit compatible with Huawei BBU3900, BBU3910, BBU5900 and BBU5900A systems.Supports 5G NR, LTE FDD, and NB-IoT, featuring 6 × CPRI optical ports and 1 × QSFP HEI interface for high-speed inter-board expansion.Delivers up to 2.4 Gbps DL / 1.2 Gbps UL throughput, ideal for macro base-station upgrades, C-RAN / D-RAN deployments, and multi-RAT network evolution.
(for BBU3900 / BBU3910 / BBU5900 / BBU5900A systems)
The UBBPg2a is a g-series universal baseband processing (UBBP) board for Huawei DBS platform BBUs. It delivers high-capacity multi-RAT baseband resources and connects to RRUs over CPRI. Compared with earlier e/d-series boards, the g-series adds enhanced 5G NR capability while retaining LTE FDD and NB-IoT support (UMTS availability depends on software/license).
Front-haul (CPRI): 6 × SFP ports (CPRI0–CPRI5); supports multiple CPRI line rates and star/chain/ring topologies.
High-speed interconnect: 1 × QSFP (HEI) for inter-board resource sharing/expansion.
Typical supported CPRI rates: 1.25 / 2.5 / 4.9 / 6.144 / 9.8 / 10.1376 Gbit/s (exact set depends on SRAN/eRAN version).
DSFP optics applicability: Huawei hardware docs list DSFP usable with UBBPg2 / UBBPg2a (and g3) on BBU5900/5900A/3910.
Supported RATs: 5G NR, LTE FDD, NB-IoT (UMTS optional per software/license).
Multi-RAT concurrency: LTE + NB-IoT + NR concurrency supported (feature mix is software/version dependent).
Layer-1 throughput (per board, ref.): DL ~2.4 Gbit/s, UL ~1.2 Gbit/s for g2/g2a class.
Signaling (BHCA, ref.): ~432,000 for g2/g2a portfolio (use project baseline for exact values).
Important: Final limits for cells / carriers / UEs / throughput depend on SRAN/eRAN version, license keys, bandwidth/MIMO, and site planning; always validate against the project capacity table.
Chassis compatibility: Works in BBU3900 / BBU3910 / BBU5900 / BBU5900A.
Typical configuration: Deployed with UMPT (main control), UPEU (power) and FAN modules in a 2U / 19-inch BBU.
RRU topology: Star, chain, dual-star/ring via six CPRI ports.
Typical board power: ~107 W (ITPrice listing).
Board dimensions (net): ≈ 313 × 154 × 19 mm (board body, not chassis).
BBU operating voltage (context): −48 V DC input with −38.4…−57 V window on BBU chassis.
Commercial code: WD2DUBBPG2A0 (also seen as WD2DUBBPG2A1 in some markets).
Part numbers observed: 03058707 (common), also 03058705 on some channel pages—confirm against the front-panel label.
Macro D-RAN / C-RAN: Add NR/LTE/NB-IoT capacity; flexible RRU mappings over 6×CPRI; DSFP optics available where specified.
Network modernization: Introduce 5G NR while preserving 4G/NB-IoT using existing DBS BBUs.
