SFP+-transceiver BlueOptics BO35J856S3D (Y3KJN-BO) — LC-duplex, 10GBASE-SR, multimode 850 nm, 300 m, 0–70 °C

The BlueOptics BO35J856S3D SFP+ transceiver is a 10GBASE-SR optical module designed for short-range multimode fiber links. It uses an 850 nm wavelength and an LC-duplex connector to deliver 10 Gbps connectivity for data centers, switches, server uplinks and other network equipment that accept SFP+ modules. The module supports link distances up to 300 meters over suitable multimode fiber and is specified to operate in environments from 0°C to 70°C.

Advantages

This SFP+ transceiver ensures 10 Gbps performance over multimode fiber with a compact LC-duplex interface compatible with standard SFP+ ports. Its short-range design provides reliable transmission for server-to-switch and switch-to-switch links within racks or across adjacent equipment rooms. The broad operating temperature range and industry-standard form factor make it suitable for conventional data center and campus networking deployments where predictable optical behavior is required.

How to use

Install the transceiver into an available SFP+ port on a compatible switch, server or optical transceiver slot, ensuring the host device supports 10GBASE-SR modules. Connect LC-duplex multimode fiber patch cables to the transceiver’s connectors, taking care to match transmit and receive channels. After physical installation, verify link status and configure interface parameters on the host device as required for your network. Follow standard electrostatic discharge (ESD) precautions when handling the module and use dust caps when the transceiver is not connected.

Recommendations

Use OM3 or OM4 multimode fiber for reliable performance at longer multimode distances and ensure patch cables are properly rated for 10 Gbps operation. Verify compatibility with the host equipment vendor’s supported transceiver list and test links after installation to confirm expected throughput and signal quality.
