Overview
Our collection of 25G BiDi SFP28 optical transceivers is engineered to maximize your fiber optic infrastructure. By utilizing bidirectional Wavelength Division Multiplexing (WDM) technology, these modules transmit and receive data over a single-fiber strand. Consequently, this provides a highly cost-effective solution for upgrading network capacity without laying new fiber, effectively doubling your existing network’s potential.
These high-performance transceivers are specifically designed for 25G Ethernet and 5G fronthaul applications, such as eCPRI/CPRI. Each SFP28 BiDi module is rigorously tested in real-world deployment scenarios to ensure seamless compatibility and carrier-grade reliability. Therefore, they represent a smart, future-proof investment for service providers and data center operators aiming for efficient network expansion.
Key Features

- High-Speed Performance: Delivers a robust 25Gbps data rate, ideal for the high-bandwidth demands of modern data centers and 5G wireless networks.
- Multiple Reach Options: Available in various distance configurations, including 10km, 20km, and 40km, to suit diverse network architectures.
- Hot-Pluggable SFP28: Conforms to the SFP28 MSA standard, allowing for easy installation and network maintenance without powering down equipment.
- Digital Diagnostics (DDM): Features built-in Digital Diagnostics Monitoring for real-time tracking of critical parameters like temperature, voltage, and optical power.
- Low Power Consumption: Engineered for power efficiency, which helps reduce operational costs and thermal load in high-density deployments.
Applications
The unique capabilities of 25G BiDi SFP28 transceivers make them the preferred choice for specific, high-value applications. Most notably, they are a cornerstone technology in 5G fronthaul networks connecting cell towers to baseband units. Moreover, they are widely used in data center interconnects, fiber-to-the-home (FTTH) rollouts, and any enterprise network environment where fiber resources are limited but bandwidth demand is high.

Advantages
The most significant advantage of deploying a 25Gbps BiDi SFP28 module is immediate and substantial cost savings on fiber infrastructure. By requiring only one fiber instead of two, you can reduce cabling expenses by up to 50%. This is particularly impactful in long-haul connections or in conduits where space is at a premium. Thus, network expansion becomes faster and more economical.
Furthermore, simplifying your cabling infrastructure with single-fiber links reduces potential points of failure and simplifies network management. In practice, this means quicker troubleshooting and higher overall network uptime. These modules provide a direct upgrade path to higher speeds on existing fiber, ensuring a seamless and efficient transition to meet growing data demands.
FAQ (Technical & product category Questions)
1. What is a 25G BiDi SFP28 transceiver?
A 25G BiDi SFP28 transceiver is a compact, hot-pluggable optical module that transmits and receives 25Gbps data over a single strand of single-mode fiber. It uses two different wavelengths of light, one for sending and one for receiving, which makes it a highly efficient single-fiber optic solution.
2. How does a single-fiber 25G transceiver work?
A single-fiber 25G transceiver works by using WDM (Wavelength Division Multiplexing) couplers to combine and separate data streams onto one fiber. One end transmits at a specific wavelength (e.g., 1270nm) and receives at another (e.g., 1330nm), while the paired module at the other end does the opposite.
3. Can I connect two identical 25G BiDi SFP28 modules?
No, you must use a matched pair of 25G BiDi SFP28 modules. For example, a module that transmits at 1270nm and receives at 1330nm must be connected to a module that transmits at 1330nm and receives at 1270nm for the link to function correctly.
4. What are the main applications for a 25Gbps BiDi SFP28 module?
The primary application is in 5G fronthaul (eCPRI) networks, which require high bandwidth over long distances with minimal fiber. Other key uses for the 25Gbps BiDi SFP28 module include data center interconnects and high-speed enterprise campus networks where fiber is scarce.
5. Is this SFP28 BiDi module compatible with my network equipment?
Our SFP28 BiDi modules are built to MSA (Multi-Source Agreement) standards, ensuring wide compatibility with major switch and router brands. They are field-proven to provide seamless integration and reliable performance in mixed-vendor environments.
6. What is the difference between a BiDi SFP28 and a standard duplex SFP28?
A BiDi SFP28 uses a single fiber optic port (Simplex LC) to transmit and receive data. In contrast, a standard duplex SFP28 requires two separate fibers and has a dual LC port, one for transmitting and one for receiving, making the single-fiber transceiver more economical.
7. What type of fiber cable is required for a 25G BiDi transceiver?
You must use a single-mode fiber (SMF) patch cable, typically OS1 or OS2, with a simplex LC connector to connect a 25G BiDi SFP28 module. Multimode fiber is not supported for these long-reach transceivers.
8. Do you offer industrial temperature 25G BiDi SFP28 modules?
Yes, we offer industrial-grade versions of the 25G BiDi SFP28 transceiver. These modules are designed to operate reliably in harsh environmental conditions with an extended temperature range of -40°C to 85°C, making them suitable for outdoor or unconditioned deployments.
