简要描述：
Baseband UBBPg2 (03058626)Buy the Huawei UBBPg2 (03058626) — a high-capacity universal baseband processing unit for Huawei BBU3900, BBU3910, and BBU5900 systems.Supports 5G NR, LTE FDD, and NB-IoT, with 6× CPRI optical interfaces and 1× QSFP HEI port for advanced baseband interconnection.Delivers up to 2.4 Gbps downlink throughput and 1.2 Gbps uplink, ideal for macro base stations, C-RAN / D-RAN, and multi-RAT network evolution.
(for BBU3900 / BBU3910 / BBU5900 systems)
The UBBPg2 is Huawei’s g-series universal baseband processing (UBBP) board for the DBS platform. It provides high-capacity multi-RAT baseband resources and connects to RRUs over CPRI. Compared to earlier e/d series, g-series boards add enhanced 5G NR, while continuing support for LTE FDD and NB-IoT (UMTS support is software/license dependent).
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 and expansion.
Typical supported CPRI rates: 1.25 / 2.5 / 4.9 / 6.144 / 9.8 / 10.1376 Gbit/s (actual set depends on SW release).
DSFP optical module applicability: Huawei’s HW description lists DSFP use 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 (UBBPg2 / g2a comparative table).
Signaling (BHCA, ref.): ~432,000 (g2/g2a table, same class as g1/g1a in some docs; use project baseline).
NB-IoT sharing with LTE FDD: NB-IoT UEs share the LTE FDD main-control limits; Huawei BBU tech specs outline shared UE/BHCA accounting.
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’s capacity table.
Chassis compatibility: Works in BBU3900 / BBU3910 / BBU5900.
Typical configuration: Deployed alongside UMPT (main control), UPEU (power), and FAN modules in a 2U 19-inch BBU.
RRU topology: Star, chain, dual-star/ring via the six CPRI ports.
Commercial code (example): WD2DUBBPG200.
Part number (example): 03058626 (UBBPg2 listing with dimensions).
Related variants in the family: UBBPg2a / g2e / g2f, etc. (market/region differ).

Software baseline matters: Supported CPRI rates, NR/LTE/NB-IoT concurrency, and capacity headroom vary by SRAN/eRAN version—confirm against the site’s software BOM.
Variant clarity: Market pages sometimes mix g2 / g2a / g2e / g2f; verify the exact PN on the front-panel label for compatibility.
