Designed for versatility in data centers, campus networks, and enterprise edges, this SFP+ module enhances throughput, reduces fiber plant complexity, and lowers operational costs. Whether you are expanding a data center spine, linking remote campuses, or upgrading uplinks to core switches, this BiDi transceiver provides a smooth, plug-and-play experience with Cisco devices while maintaining compliance with industry standards. The module is built to endure demanding network conditions and provides robust support for long-haul connections, all while remaining easy to install and manage in a busy IT environment.

• Designed for Cisco SFP+ compatibility: This 10GBASE-BX20D-I module is engineered to work with Cisco switches, routers, and servers, offering plug-and-play integration that minimizes deployment time and reduces the risk of compatibility issues. It aligns with Cisco’s SFP+ ecosystem, making it a reliable choice for enterprises standardizing on Cisco hardware.
• BiDi 10GBASE-BX20D-I transceiver: Bi-directional transmission over a single SMF fiber pair uses distinct wavelengths for transmit and receive, typically enabling a single fiber to carry both directions. This design reduces fiber count, simplifies fiber management, and lowers materials costs in environments where fiber availability or trenching is a concern.
• Long-distance performance on SMF: Engineered for mid- to long-reach links, this BiDi transceiver supports extended distances up to 20 kilometers when paired with the appropriate single-mode fiber and network equipment. It’s ideal for data center interconnects, campus backbones, and uplinks between distant distribution closets or core devices.
• High reliability and ease of deployment: The module adheres to industry-standard SFP+ form factor, is hot-swappable in compatible equipment, and includes robust build quality to withstand installation in tight racks or crowded data center cabinets. It also supports monitoring features commonly available on modern transceivers, contributing to stable operation over time.
• Diagnostics and management capabilities: Digital Optical Monitoring (DOM) support is typically available on SFP+ BiDi modules, enabling real-time visibility into laser temperature, current, optical power, and other critical parameters. This insight helps with proactive maintenance and rapid troubleshooting, minimizing downtime and optimizing link performance.

How to install StarTech.com Cisco SFP-10G-BX20D-I Compatible SFP+ Module

• Prepare the Cisco device: Power down the server or network device if required by your policy or if you are performing initial installation in a non-hot-swap environment. In many cases, hot-swapping is supported for SFP+ modules, but always follow your equipment’s operational guidelines.
• Remove the existing SFP+ module (if replacing): Gently unlock the SFP+ module from the housing using the device’s release latch, and carefully slide the old module out of the SFP+ slot.
• Insert the StarTech SFP+ module: Align the module with the SFP+ slot, ensuring the connector pins and rails engage properly. Push firmly until you hear or feel the latch click, indicating a secure seated position.
• Connect the fiber: Attach a duplex LC fiber optic cable to the module’s LC connectors on the fiber end. Ensure the TX/RX direction is correct and that the link alignment matches your network topology (the TX side should connect to the RX side of the remote device as per your design).
• Verify and monitor: Power up the device (if you powered down) and verify link status via the device’s management interface. If DOM is supported, monitor the transceiver’s operational parameters (temperature, current, optical power) to confirm a healthy link and expected performance.

Frequently asked questions

• Q: Is this module compatible with all Cisco SFP+ ports?

  A: This StarTech.com module is designed for Cisco SFP+ interfaces and is intended to provide plug-and-play compatibility with Cisco switches, routers, and servers that support 10GBASE-BX BiDi transceivers. Always check your device’s compatibility matrix and ensure firmware is up to date for optimal operation.

• Q: What fiber type and distance can I use with this transceiver?

  A: The module is intended for single-mode fiber (SMF) with a standard duplex LC connection. It supports distances up to 20 kilometers under appropriate network conditions and with compatible optical components, enabling long-haul links between data centers and campuses.

• Q: How does BiDi work in this module?

  A: BiDi, or bi-directional transmission, uses two wavelengths on a single fiber to carry data in opposite directions. This reduces the number of fibers required for a link and simplifies fiber management in dense deployments, while maintaining full 10 Gbps bandwidth per direction when configured correctly.

• Q: Does the module support Digital Optical Monitoring (DOM)?

  A: Many SFP+ BiDi modules include DOM support, providing real-time diagnostic data such as laser temperature, current, and received optical power. If your devices enable DOM, you can actively monitor link health and anticipate potential issues before they impact performance.

• Q: How do I know if the module is working properly after installation?

  A: Confirm that the link status on both ends is active and that the port shows 10 GbE operation. Use the management interface of your Cisco device to check optical power levels, ROM/DOM data if available, and any error counters. If issues arise, re-check fiber connections, ensure TX/RX alignment, verify that the correct SFP+ slot is used, and consult device logs for more details.
