Fiber optic transceiver BlueOptics XT61J-BO 40000 Mbit/s QSFP

The BlueOptics XT61J-BO is a QSFP fiber optic transceiver module designed for 40 Gbit/s network links. The module supports a maximum data transfer rate of 40000 Mbit/s, operates at a wavelength of 832 nm and is powered by a 3.3 V input. Housed in a durable metal casing with a compact form factor and a weight of 20 g, the transceiver is intended for short-range, high-speed data communication and integrates into QSFP-compatible ports on switches, routers and network appliances.

Advantages

The BlueOptics XT61J-BO combines a high 40 Gbit/s throughput with a compact QSFP connector format and a robust metal housing. Its silver metal casing provides mechanical protection and thermal dissipation while the low weight and standard QSFP interface simplify installation and replacement. The module supports up to 100 m transmission distance over appropriate multimode fiber, making it suitable for data center spine-and-leaf links and other short-reach optical connections.

Suitable for

• High-density data center links and server interconnects
• Aggregation and switching connections in campus networks
• Short-reach optical links up to 100 m over multimode fiber
• Upgrading or replacing QSFP transceivers in compatible network equipment

How to use

Install the BlueOptics XT61J-BO by inserting the QSFP transceiver into a compatible QSFP slot on a switch, router or network appliance while the device is powered down or following the equipment manufacturer's hot-plug guidelines. Connect appropriate multimode fiber cables to the module using matching MPO/MTP or QSFP-compatible cabling assemblies as required by the host equipment. Ensure the host device is configured for a 40 Gbit/s link and verify link status and diagnostics through the network device management interface.

Recommendations

Use multimode fiber rated for the intended distance and check polarity and cabling standards before powering the link. Keep the transceiver in its dust cap when not installed, avoid mechanical shock, and follow the host equipment manual for ESD and hot-swap procedures. For reliable operation, monitor SFP/QSFP diagnostics in the network management system and replace modules that show persistent errors or degraded optical parameters.
