Cisco SFP-10G-BX100D Compatible SFP+ 10GBASE-BX100-D BiDi 1550nm-TX/1490nm-RX 100km DOM Simplex LC/UPC SMF Optical Transceiver Module

Overview

This is a high-performance SFP+ 10G BiDi 100km transceiver, engineered for ultra-long-reach network connections. It is fully compatible with Cisco SFP-10G-BX100D specifications, offering a robust and cost-effective alternative for service providers and enterprises. This module doubles your network capacity by using a single strand of fiber for both sending and receiving data.

By leveraging Bi-Directional (BiDi) WDM technology, this optical transceiver dramatically reduces fiber cabling costs. In practice, this is ideal for long-haul links where deploying new fiber is prohibitively expensive. Consequently, it provides a smart, efficient path for network expansion or upgrades over existing single-fiber infrastructure.

Key Features

• Ultra Long-Haul Reach: Delivers reliable 10Gbps data transmission up to an impressive distance of 100km.
• Single Fiber Operation: Utilizes WDM technology with a 1550nm-TX/1490nm-RX wavelength pair to transmit and receive on one fiber.
• Guaranteed Compatibility: Functions as a seamless, plug-and-play replacement for the Cisco SFP-10G-BX100D module.
• Reduced Infrastructure Cost: The single fiber design immediately halves fiber cabling requirements, saving significant capital expenditure.
• Hot-Pluggable SFP+ Design: Allows for insertion or removal from network devices without causing service interruption.
• Digital Optical Monitoring (DOM): Enables real-time monitoring of critical parameters like optical power, temperature, and voltage for network health.

Applications

This versatile 10GBASE-BX100-D SFP+ module is field-proven for establishing stable, long-distance links where fiber resources are limited. It is the go-to choice for service providers and large-scale networks. For this reason, it is frequently deployed in:

FAQ (Technical & Product Questions)

1. What is a BiDi SFP+ transceiver?

A BiDi (Bi-Directional) SFP+ transceiver is an optical module that can transmit and receive data over a single fiber strand. It achieves this using two different wavelengths of light, one for sending and one for receiving, which makes the SFP+ 10G BiDi 100km module extremely efficient for conserving fiber.

2. Do I need a special fiber cable for this module?

This module requires a standard single-mode fiber (SMF) patch cable. However, since it is a BiDi transceiver, you will use a cable with a Simplex LC connector on each end, as it only connects to a single fiber strand, not a pair.

3. Can I connect two SFP-10G-BX100D modules together?

No. BiDi transceivers must be deployed in matched pairs. This Cisco SFP-10G-BX100D compatible module (Downstream) must be linked with its upstream counterpart, the SFP-10G-BX100U (which transmits at 1490nm and receives at 1550nm), at the other end of the fiber.

4. What does 1550nm-TX/1490nm-RX mean?

This specification defines the wavelengths used by the BiDi module. The 1550nm-TX means this transceiver transmits (TX) a 1550nm light signal, and the 1490nm-RX means it receives (RX) a 1490nm signal from the module at the opposite end of the link.

5. Is this 10GBASE-BX100-D SFP+ compatible with other brands?

Yes. While specifically coded to ensure compatibility with Cisco devices, this 10GBASE-BX100-D SFP+ is built to Multi-Source Agreement (MSA) standards. This allows it to function correctly in networking hardware from any vendor that adheres to MSA specifications.

6. What is the main advantage of using a 100km BiDi SFP+?

The main advantage is cost savings and capacity expansion. For a 100km link, the cost of fiber cable is substantial. By using a single fiber 10G transceiver, you can either deploy a new link using only one fiber or double the capacity of an existing duplex fiber link by running two separate BiDi links.

7. What type of laser is used for a 100km reach?

To achieve a 100km reach, this transceiver uses a high-power Externally Modulated Laser (EML). An EML provides a very clean, stable signal with low dispersion, which is essential for maintaining signal integrity over such extreme distances.

8. Does this transceiver support Digital Optical Monitoring (DOM)?

Yes, this optical module fully supports DOM (also known as DDM). This feature allows network administrators to monitor crucial real-time data from the SFP+ 10G BiDi 100km transceiver, including transmit/receive power, temperature, and voltage, to ensure link stability.
