SFP-10G-BX40U-I Use Case
FTTH PON Upstream Aggregation with SFP-10G-BX40U-I-SFP+
Internet service providers deploy the SFP-10G-BX40U-I-SFP+ in OLT chassis to aggregate upstream traffic from distributed ONTs over a single fiber link spanning up to 40 km. This bidirectional 10G transceiver halves fiber count, slashes CAPEX and operational complexity, and delivers symmetrical high-speed upstream performance for thousands of residential subscribers.
Metro Data Center Interconnect over 40 km Single-Fiber Links
Enterprises use the SFP-10G-BX40U-I-SFP+ to connect geographically separated data centers with a single-fiber, bidirectional 10G link up to 40 km. The compact SFP+ module maximizes rack density, lowers fiber infrastructure costs, and provides low-latency, high-throughput connectivity for mission-critical applications such as real-time backup, SAN replication and disaster recovery.
5G C-RAN Fronthaul Transport Using SFP-10G-BX40U-I-SFP+
Telecom operators integrate the SFP-10G-BX40U-I-SFP+ in fronthaul interfaces to link remote radio heads (RRHs) and centralized baseband units (BBUs) over distances up to 40 km. Its bidirectional 10G capability reduces fiber deployment by 50%, ensures ultra-low latency and high reliability, and supports enhanced mobile broadband and ultra-reliable low-latency communications in dense urban and rural 5G networks.
