Use for 400 Gbit/s aggregation and spine-to-leaf connections over OM3/OM4.

## Long description

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.
Suitable for
 Data center spine-to-leaf and aggregation links
 High-density switch deployments requiring 400G ports
 Short-range multimode fiber connections over OM3/OM4 up to 50 m
 Enterprise core and distribution layer connectivity
Key specifications
 Form factor: OSFP (Octal Small Form Factor Pluggable)
 Data rate: 2 × 400 Gbit/s (parallel SR4 lanes)
 Medium: Multimode fiber (OM3/OM4)
 Maximum reach: up to 50 meters on multimode fiber
 Wavelength: multimode parallel lanes (VCSEL-based parallel transmission)
 Installation: hot-pluggable module
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.
Usage 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.
