Network Media Converter Cisco 1000BASE-BX10-D

The Cisco 1000BASE-BX10-D SFP is a small form-factor pluggable Gigabit Interface Converter designed for hot-swappable installation in Gigabit Ethernet ports and slots. It implements the IEEE 802.3ah 1000BASE-BX10-D profile to transmit and receive over a single strand of single-mode fiber with a maximum link distance of 10,000 m. The transceiver uses a single LC connector and supports digital optical monitoring (DOM) for real-time reporting of optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.

Advantages

The SFP supports single-fiber operation up to 10 km, enabling fiber links where only one fiber strand is available. Compliance with IEEE 802.3z and IEEE 802.3ah standards ensures interoperability with a wide range of network equipment. Built-in DOM provides operational visibility for diagnostics and remote monitoring. The module is compact, hot-swappable, and lightweight, simplifying installation and maintenance.

Suitable for

• Point-to-point Gigabit Ethernet links over single-mode fiber where only one fiber strand is available
• Network equipment requiring IEEE-compliant SFP modules (switches, routers, media converters)
• Environments that require remote optical monitoring and diagnostics

Key specifications

• Standards compliance: IEEE 802.3z, IEEE 802.3ah
• Digital Optical Monitoring (DOM): supported
• Laser class: Class 1
• Weight: 0.075 kg

How to use

Insert the SFP module into a compatible Gigabit Ethernet port or slot while the host device is powered on or off (hot-swappable). Pair a 1000BASE-BX10-D module with a corresponding 1000BASE-BX10-U module on the far end, using a single strand of standard single-mode fiber with LC connectors. Ensure correct fiber polarity and that the transmit and receive wavelengths match the remote module. Verify link status on the host device and use DOM to monitor operational parameters via the supporting network equipment.

Usage recommendations

Use clean LC connectors and adhere to manufacturer guidelines for ESD and laser safety. Match BX-D and BX-U types on opposite ends of the link, maintain appropriate optical power margins within the −3 to 9 dBm transmit range, and configure monitoring on compatible devices to detect degradation early.
