SFP+-transceiver BlueOptics ATTJ-BO (10GBASE-SR, LC-duplex, 850 nm, multimode, 300 m, DDM)

BlueOptics ATTJ-BO is a compact SFP+ optical transceiver designed for short-range 10 Gigabit Ethernet links over multimode fiber. The module supports the 10GBASE-SR standard, transmits at 850 nm using a VCSEL source and connects via an LC duplex interface. It is intended for use in network switches, servers and uplink ports in data center and enterprise environments where reliable 10 Gb/s short-reach fiber connectivity is required. The transceiver includes Digital Diagnostic Monitoring (DDM/DOM) to monitor operating parameters and has an operating temperature range from 0°C to 70°C.

Advantages

The module offers a compact SFP+ form factor compatible with 10Gb optical ports and supports multimode fiber links up to 300 meters, providing flexibility for typical rack-to-rack and equipment-to-equipment connections in data centers. Built-in DDM enables real-time monitoring of optical power, temperature and laser bias, which helps maintain link reliability and assists troubleshooting. The LC-duplex connector and 850 nm VCSEL design ensure interoperability with common multimode cabling and established 10GBASE-SR deployments.

Key specifications

How to use

Install the SFP+ transceiver into a compatible SFP+ port on a switch, server or other network device, ensuring the module is fully seated and latched. Connect LC-duplex multimode fiber patch cords to the transmit and receive ports, observing correct polarity. Verify link status on the host device and check DDM parameters via the management interface if available. When removing the module, power down or follow hot-swap procedures recommended by the equipment vendor to avoid signal disruption.

Recommendations

For optimal performance, use OM3/OM4 multimode fiber for links approaching the maximum reach and maintain clean LC connectors to prevent signal loss. Verify that the host equipment supports SFP+ modules and 10GBASE-SR optics. Monitor DDM values regularly to detect potential issues with optical power or temperature.
