SFP+ transceiver BlueOptics BO35J856S3D 10GBASE-SR multimode fiber 850nm 300m

The SFP+ transceiver BlueOptics BO35J856S3D is a hot-pluggable 10GBASE-SR module designed for short-range multimode fiber links at 850 nm with an approximate reach of 300 meters. Intended for data center and enterprise network environments, this module provides 10 Gigabit Ethernet connectivity for compatible switches, routers and media converters. The compact SFP+ form factor supports high-density port configurations and can be used for uplinks, server connections and aggregation over OM3/OM4 multimode fiber within the specified distance.

Advantages

This SFP+ transceiver offers a compact, industry-standard form factor that enables hot-swap installation and flexible network upgrades without powering down equipment. It supports 10GBASE-SR signaling at 850 nm optimized for multimode fiber, providing predictable short-range performance up to approximately 300 meters. The module is suitable for high-density deployments and reduces the need for custom cabling solutions by using common multimode fiber types.

Key specifications

How to use

Install the transceiver into an SFP+ port on a compatible switch, router or media converter until it clicks into place. Connect duplex multimode LC fiber patch cords to the transceiver and the remote device, ensuring correct transmit/receive orientation. Verify link status and speed via the host device management interface. For removal, unlock the module according to the host device instructions and gently pull it from the port; handle the module by its housing and protect the fiber endfaces with dust caps when disconnected.

Recommendations

Use OM3 or OM4 multimode fiber to achieve the stated reach and ensure that patch cords and connectors are clean and intact. Confirm that the network device supports third-party SFP+ modules and that firmware settings allow 10GBASE-SR operation. Avoid bending fiber beyond specified radius limits and maintain proper optical link budgeting for reliable 10 Gigabit performance.
