SFP-transceiver BlueOptics BO15C5531640D 1000BASE-BX-D singlemode glasvezel 40 km

The BlueOptics BO15C5531640D SFP transceiver implements 1000BASE-BX-D singlemode fiber connectivity for links up to 40 km. Designed for gigabit Ethernet, this compact SFP module supports bidirectional (BIDI) transmission over a single fiber using a defined wavelength, making it suitable for point-to-point connections between switches, routers and optical line modules where space-saving SFP form-factor and long-reach singlemode operation are required.

Advantages

This SFP transceiver offers a compact and hot-pluggable design that fits standard SFP ports, enabling straightforward insertion and removal without system downtime. It supports gigabit Ethernet data rates and bidirectional single-fiber operation, reducing fiber cabling requirements while maintaining reliable long-distance connectivity. The module is engineered for compatibility with a wide range of network equipment that accepts SFP optics and provides stable performance across the specified reach.

Suitable for

• Long-reach gigabit Ethernet links between buildings or data center racks
• Connecting switches and routers in metropolitan or campus networks
• Optical line modules and small form-factor installations requiring BIDI single-fiber links
• Replacing damaged or upgrading existing singlemode SFP optics to extend link distance to 40 km

Key specifications

• Interface: SFP (small form-factor pluggable)
• Standard: 1000BASE-BX-D (Gigabit Ethernet)
• Fiber type: Singlemode fiber
• Maximum reach: up to 40 km (depending on fiber quality and link budget)
• Transmission: Bidirectional (BIDI) over a single fiber using wavelength-specific TX/RX
• Form factor: Hot-pluggable SFP module

How to use

Insert the SFP transceiver into a compatible SFP port on the switch, router or optical module until it latches. Connect the singlemode fiber patch cable using the appropriate connector type and ensure the fiber polarity matches the bidirectional wavelength assignment. Power on and verify the link status on the network device; the interface should negotiate a gigabit Ethernet connection. If required, configure the port settings on the connected equipment (speed, duplex, auto-negotiation) according to network policies.

Recommendations

Use high-quality singlemode fiber and maintain proper cleaning of connectors to ensure optimal signal performance. Verify the wavelength pairing when deploying bidirectional modules — mismatched TX/RX wavelengths will prevent link establishment. For reliable operation at the maximum distance, confirm the link budget with actual fiber attenuation and any inline components such as splices or connectors.
