Optische OSFP-transceiver BlueOptics BO30X3851S0D-BO 2×400GBASE-SR4, multimode tot 50 m

The BlueOptics BO30X3851S0D-BO OSFP optical transceiver is a hot-pluggable module designed for short-range multimode fiber links. It supports 2×400GBASE-SR4 operation, providing parallel four-lane multimode transmission for aggregated 400 Gbit/s connections. The module fits standard OSFP ports and is suited for high-density data center and enterprise switching equipment, enabling spine-to-leaf and aggregation links over OM3 and OM4 multimode fiber up to 50 meters.

Advantages

This OSFP transceiver offers high port density in an OSFP form factor and supports dual 400G lanes for flexible deployment in modern network architectures. Its multimode SR4 design enables low-latency, short-range connectivity with reduced cabling complexity. Hot-pluggable installation simplifies maintenance and hardware upgrades without disrupting nearby equipment.

Key specifications

How to use

Insert the OSFP module into a compatible OSFP port on the switch or router while the host supports hot-pluggable optics. Connect the four-lane multimode MPO trunk cables to the module ensuring correct polarity and fiber type (OM3/OM4). Verify link state and port configuration on the host device; set appropriate interface speed and lane aggregation or host-side configuration required for 400G operation. For maintenance, remove the module by pulling the ejector mechanism following the host vendor’s hot-swap instructions.

Recommendations

Use OM3 or OM4 multimode trunk cables with MPO/MTP connectors rated for 400G parallel SR4 applications and keep multimode patching under the specified 50 m reach. Follow the switch vendor guidance for lane mapping and firmware compatibility to ensure stable 2×400G operation.
