SFP-transceiver BlueOptics 3269-BO (BO05C856S5D) LC-duplex 1000BASE-SX multimode 850nm 550m DDM

The BlueOptics 3269-BO (BO05C856S5D) SFP transceiver is a compact module designed for 1000BASE-SX multimode fiber links. It uses an LC-duplex connector and transmits at an 850 nm wavelength, enabling reliable gigabit connections over multimode fiber with reach up to 550 meters. The module supports digital diagnostic monitoring (DDM/DOM) and is rated for operation in ambient temperatures from 0°C to +70°C, making it suitable for standard indoor LAN and campus network environments, including installation in gigabit switches, routers and media converters.

Advantages

The transceiver provides a small form-factor and hot-pluggable design that simplifies installation and replacement in compatible SFP ports. Integrated DDM/DOM functionality allows real-time monitoring of parameters such as optical power and temperature for easier fault finding and maintenance. Using an LC-duplex interface and standardized 850 nm optics ensures compatibility with common multimode cable types and passive LAN infrastructure. The operating temperature range and support for 1000BASE-SX make it suitable for typical enterprise and education network deployments.

How to use

Ensure the network device supports SFP modules and that the SFP port is compatible with 1000BASE-SX optics. Power down the device if recommended by the equipment manufacturer, remove any dust caps from the SFP and fiber connectors, then insert the module into the SFP slot until it latches. Connect LC-duplex multimode fiber patch cables, observing transmit/receive orientation. After insertion and powering the device, verify link status on the host equipment and check DDM/DOM parameters if diagnostics are required. Follow the switch or router manual for any software configuration needed to enable the SFP port and link aggregation or VLAN settings.

Recommendations

Use multimode fiber of appropriate grade (OM1/OM2/OM3/OM4) and verify maximum reach for the specific fiber type and network margin. Keep transceiver and connector dust caps in place when not in use, handle fibers and connectors with care to avoid contamination, and consult the host device documentation for compatibility notes and firmware requirements.
