Overview
This transceiver is a high-performance SFP+ module engineered for 100% compatibility with the Cisco SFP-10G-BX60D. It leverages Bidirectional (BiDi) technology to provide 10 Gigabit Ethernet connectivity over a single strand of fiber, which is essential for networks where fiber resources are limited or costly to expand. This module is a critical component for service providers and enterprises aiming to maximize their existing fiber infrastructure.
Functioning as the ‘Downstream’ part of a BiDi link, this module transmits on a 1330nm wavelength and receives on a 1270nm wavelength. It is fully compliant with the 10GBASE-BX60-D standard and is designed to establish a stable data link of up to 60 kilometers over Single-Mode Fiber (SMF). It must be paired with an ‘Upstream’ module (SFP-10G-BX60U) at the opposite end of the fiber to complete the circuit.
Key Features
- Fully compatible with networking devices requiring the Cisco SFP-10G-BX60D part.

Applications
The SFP-10G-BX60D compatible module is purpose-built for applications that require long-reach 10G connectivity but are constrained by the number of available fiber strands. It is commonly deployed in telecommunications access networks, metro Ethernet links, and inter-building campus networks. By enabling full-duplex communication on a single fiber, it provides an immediate, cost-effective upgrade path without the need for new fiber installation.

Cross-Platform Compatibility
Programmed for seamless integration with Cisco equipment, this module also adheres to the SFP+ Multi-Source Agreement (MSA). This ensures broad interoperability with networking equipment from other major manufacturers that support the 10GBASE-BX60-D standard. For a functional link, this ‘Downstream’ module must be paired with a corresponding ‘Upstream’ module at the other end of the fiber.

Important Note: This is a ‘Downstream’ (D) module and must be paired with a corresponding ‘Upstream’ (U) module (e.g., SFP-10G-BX60U) at the opposite end of the fiber link to establish a connection.
Advantages
The primary advantage of the SFP-10G-BX60D BiDi module is the substantial reduction in capital expenditure on fiber optic cabling. It effectively doubles the capacity of existing fiber infrastructure, deferring the high cost of laying new fiber pairs. This makes it a highly efficient solution for scaling network capacity, reducing installation complexity, and accelerating the deployment of high-speed services.
FAQ (Technical & Product Questions)
1. What does the ‘D’ in SFP-10G-BX60D signify?
The ‘D’ stands for Downstream. In a BiDi link, one module is designated ‘Downstream’ and the other ‘Upstream’ (‘U’). The SFP-10G-BX60D is the downstream module that transmits at 1330nm and receives at 1270nm.
2. What module must I pair this with?
To create a functional 60km BiDi link, you must pair this SFP-10G-BX60D (Downstream) module with its counterpart, the SFP-10G-BX60U (Upstream) module, at the other end of the fiber. The two modules use opposite wavelengths to communicate.
3. Can I use two SFP-10G-BX60D modules to create a link?
No, you cannot. A link can only be established between one ‘Downstream’ (D) and one ‘Upstream’ (U) module. Using two of the same modules will not work because their transmit and receive wavelengths will not align.
4. Is this module compatible with multi-mode fiber (MMF)?
No. This transceiver is specifically designed for long-haul transmission over Single-Mode Fiber (SMF). It will not function correctly with any type of multi-mode fiber.
5. What makes this different from the SFP-10G-BX60U?
The only difference is the wavelengths used. The SFP-10G-BX60D (Downstream) transmits at 1330nm and receives at 1270nm, while the SFP-10G-BX60U (Upstream) does the opposite (TX 1270nm / RX 1330nm).
6. Will this module work in a non-Cisco switch?
Yes, because it is MSA compliant, it should function in equipment from other vendors that do not lock their ports and support the 10GBASE-BX60-D standard. However, it is specifically programmed for optimal compatibility with Cisco devices.
7. What connector does the SFP-10G-BX60D use?
It uses a Simplex LC connector, which is designed to connect to a single strand of fiber optic cable, in line with its BiDi functionality.
8. What is the maximum distance for this module?
When paired correctly with an SFP-10G-BX60U, this module can support a link distance of up to 60 kilometers (approximately 37.3 miles) over standard single-mode fiber.
