Cisco SFP-10G-BXD Compatible 10GBASE-BX10-D BiDi SFP+ 1330nm-TX/1270nm-RX 10km DOM Simplex LC SMF Transceiver Module

Overview

Upgrade your network capacity efficiently with the SFP-10G-BXD Compatible transceiver. This Bidirectional (BiDi) SFP+ module is the industry standard for single-fiber 10G connectivity, allowing you to double the potential of your existing fiber plant by transmitting and receiving data simultaneously over a single strand of Single-Mode Fiber (SMF).

The SFP-10G-BXD (“Downstream”) operates at a distance of up to 10 kilometers. It transmits data using a 1330nm laser and receives data at 1270nm. To establish a functioning link, this module must be connected to its complementary partner, the SFP-10G-BXU (“Upstream”), at the other end.

Key Features

• Bidirectional Technology: Uses WDM to send and receive on one fiber, saving cabling costs.
• Wavelengths: Transmits at 1330nm / Receives at 1270nm.
• Reach: Supports links up to 10km (6.2 miles) on standard SMF.
• Connector: Simplex LC interface (Single port).
• Compliance: Fully MSA compliant and meets IEEE 802.3ae 10GBASE-BX10 standards.
• Monitoring: Includes Digital Optical Monitoring (DOM) for real-time diagnostics.

Applications

The SFP-10G-BXD is the go-to solution for enterprise and service provider networks:

• Fiber Exhaustion Relief: ideal for older buildings or ducts where no spare fiber strands are available.
• Enterprise Uplinks: Connecting floor switches to the core network without using dual-fiber pairs.
• Internet Service Providers (ISPs): Delivering high-speed business ethernet or residential fiber services.
• Cellular Backhaul: Connecting base stations where fiber lease costs are high.

Specifications

Cross-Platform Compatibility

Our 10GBASE-BX10-D modules are coded for seamless interoperability with major networking brands. This specific “BXD” part number is widely recognized and compatible with equipment including:

Advantages

The primary benefit of the SFP-10G-BXD is cost reduction. By utilizing BiDi technology, you effectively double your fiber capacity instantly. Instead of pulling new cable or leasing expensive dark fiber pairs, you can run two separate 10G links on a duplex cable that previously only supported one link. This module offers a plug-and-play solution to bandwidth bottlenecks.

FAQ (Technical & Product Questions)

1. What is the difference between BXD and BXU?

The difference is the wavelengths they use. BXD (Downstream) Transmits at 1330nm and Receives at 1270nm. BXU (Upstream) does the opposite: Transmits at 1270nm and Receives at 1330nm. You always need one of each to form a link.

2. Can I connect this to a standard SFP-10G-LR module?

No. A standard LR module uses 1310nm for both transmitting and receiving on two separate fibers. The BXD module uses different specific wavelengths (1330/1270) on a single fiber. They are not compatible.

3. Is this compatible with Cisco switches?

Yes, this module is coded to be fully compatible with Cisco switches, routers, and firewalls, acting as a drop-in replacement for the SFP-10G-BXD-I or SFP-10G-BXD.

4. Can I use a patch cord with a Blue connector?

Yes. The standard connector for these modules is a UPC (Ultra Physical Contact) LC connector, which is typically Blue. Green (APC) connectors should generally be avoided unless your specific passive optical network requires them.

5. Does this support 10km exactly?

10km is the standard rating, but actual distance depends on the quality of your fiber and the number of splices/connectors. In high-quality fiber plants, it can often reach slightly further, but for guaranteed stability, we recommend keeping runs within the 10km limit.
