## Summary description

Compact SFP+ transceiver BlueOptics BO35J856S3D supporting 10GBASE-SR at 850 nm for short-reach multimode fiber links. Designed for 10 Gbps Ethernet, it fits standard SFP+ ports and enables high-speed connectivity between switches, servers, and storage devices. Ideal for data center uplinks and campus networks where reliable short-range optical links are needed.

## Long description

BlueOptics BO35J856S3D is a compact SFP+ transceiver module designed for 10GBASE-SR operation at 850 nm over multimode fiber. The module supports 10 Gbps Ethernet links for short-reach connections and is compatible with standard SFP+ ports. Its form factor and optical interface make it suitable for linking switches, servers and storage equipment in data centers and enterprise LANs where reliable short-distance optical connectivity is required.
Advantages
The transceiver offers a small SFP+ form factor that conserves port space while providing 10 Gbps throughput. Operating at 850 nm for multimode fiber, it enables low-latency, high-bandwidth links for short distances with stable optical performance. Compatibility with standard SFP+ cages and electrical interfaces simplifies installation and replacement. Its construction is appropriate for dense networking environments and typical temperature conditions encountered in server rooms and network racks.
Suitable for
10 Gbps uplinks between switches in data centers
Connections between servers and top-of-rack switches
Short-reach links within campus and enterprise LANs
Storage area network links requiring 10 Gbps bandwidth
Key specifications
Data rate: 10 Gbps duplex
Optical wavelength: 850 nm
Fiber type: multimode fiber (MMF)
Reach: short-range multimode links (typically up to the multimode fiber modal bandwidth limits)
Form factor: SFP+ compatible
Connector type: standard duplex LC
How to use
Install the SFP+ transceiver into an available SFP+ port until it seats securely, ensuring the module latches according to the equipment manufacturer’s instructions. Connect multimode duplex LC patch cables between transceivers on each end of the link, follow correct fiber polarity, and verify link status on connected devices. Configure the network interfaces on switches or servers as required for 10 Gbps Ethernet operation and monitor optical receive/transmit levels to ensure proper signal quality.
Usage recommendations
Use high-quality multimode fiber and LC duplex patch cables rated for 850 nm to achieve expected reach and performance. Validate compatibility with your switch or server vendor if required by the equipment, and avoid exposing the transceiver to excessive dust or mechanical stress during insertion or removal.
