简要描述：
Baseband 6648 （KDU 137 0015/11 ）Buy the Ericsson Baseband 6648 (KDU 137 0015/11) — a 5G-ready RAN Compute unit supporting NR, LTE, and mixed-mode operation.Features 12 × CPRI/eCPRI SFP28 ports, 3 × 25G SFP28 interfaces, 1 × QSFP28 uplink, and dual −48 V DC power inputs in a compact 1U / 19-inch chassis.Delivers up to 15 Gbps downlink throughput, ideal for macro 5G, C-RAN, and high-capacity LTE deployments.
The Ericsson Baseband 6648 is a high-capacity RAN Compute unit optimized for 4G LTE and 5G NR, supporting NR-only, LTE-only, or mixed NR+LTE operation. It provides switching, timing, traffic management, baseband processing and radio interconnect over CPRI/eCPRI. Ericsson positions 6648 as the strongest member of its RAN Compute family, delivering ~10–15 Gbit/s downlink capacity at the site level (reference figure).
Form factor: 1U, 19-inch rack unit; self-contained environmental control with field-replaceable fan tray.
Radio interconnect (RI): 12 × SFP28 ports supporting CPRI or eCPRI to radios/AIR. All RI ports support CPRI & eCPRI.
High-speed transport: 3 × 10/25G SFP28 + 1 × 1G RJ45, plus 1 × QSFP28 (4×25G) for higher backhaul/aggregation.
External alarms: 8 inputs.
Power: Dual −48 V DC feeds.
Typical PN / ordering codes seen in the field: KDU 137 0015/11 (Baseband 6648 main PN) and BKV 106 236/1 (bundle/code on some channels). Always verify against the unit nameplate.
Operating modes: NR, LTE, and NR+LTE mixed mode; supports Elastic RAN and backhaul cascading.
Site capacity indicator: ~10–15 Gbit/s DL (Ericsson RAN Compute blog reference; exact capacity depends on configuration/licenses).
25G front-haul: Simplified installation to new AIR/Radio over 25 G interfaces.
Planning note: Final sector/cell/throughput limits depend on ERS software baseline, licenses, radio mix, and topology.
Dimensions (H×W×D): 44 × 483 × 383 mm (1U × 19" × ~383 mm). Some early slides list “<352 mm”; use 383 mm as the conservative mechanical depth unless your site doc specifies otherwise.
Weight: ~8.16 kg (typical).
Ingress protection: IP20 (indoor).
NEBS/approvals: Listed with GR-63 / GR-1089 and CE/CB in published tech sheets.
Radio compatibility: Interfaces to Ericsson Radio / AIR portfolio (e.g., 22xx / 44xx / 88xx) over CPRI/eCPRI.
Topologies: Star / daisy-chain / ring; supports direct inter-BBU (IDLA/IDLB) connections and Y-cable options for NR CA with other basebands (e.g., 6630 / 5216).
High-capacity 5G mid-band/high-band sites; mixed 4G/5G modernization.
C-RAN/D-RAN hubs needing dense CPRI/eCPRI fan-out (12 RI ports).
Energy/space optimization vs. multi-box legacy stacks (25G front-haul to AIR radios).
