+86 13823237984 2.5G SFP transceiver modules, also known as small form-factor pluggable (SFP) transceivers, are compact, hot-pluggable devices that enable high-speed data transmission over optical fiber. They are widely used in various applications, including data centers, enterprise networks, and telecommunications. 2.5G SFP transceivers offer a cost-effective and efficient solution for upgrading existing networks to support higher bandwidth requirements.
Types of 2.5G SFP Transceivers
There are two main types of 2.5G SFP transceivers:
- 2.5GBASE-SR: These transceivers support a maximum transmission distance of 2 kilometers (km) over multimode fiber (MMF).
- 2.5GBASE-LR: Designed for longer-haul applications, these transceivers can transmit data up to 10 km over SMF.
In addition to these two main types, there are also several specialized 2.5G SFP transceivers available, such as those with copper connectors for short-reach applications.
Key Specifications of 2.5G SFP Transceivers
2.5G SFP transceivers are characterized by several important specifications:
- Data rate: 2.5 gigabits per second (Gbps)
- Wavelength: 850 nm for MMF and 1310 nm or 1550 nm for SMF
- Connector: LC duplex (MMF) or LC simplex (SMF)
- Reach: 2 km or 10 km depending on the type
- Power consumption: Less than 1 watt
Applications of 2.5G SFP Transceivers
2.5G SFP transceivers are widely used in a variety of applications, including:
- Data centers: Connecting servers, storage devices, and network switches
- Enterprise networks: Connecting workstations, routers, and firewalls

Benefits of 2.5G SFP Transceivers
2.5G SFP transceivers offer several advantages over traditional optical transceivers:
- Cost-effectiveness: They are more affordable than higher-speed transceivers, making them a cost-effective solution for many applications.
- High-speed performance: They support data rates of up to 2.5 Gbps, enabling high-speed data transmission for a wide range of applications.
- Long reach: They can transmit data over long distances, making them suitable for both short-haul and long-haul applications.
- Compact size: Their small form factor makes them easy to install and maintain.
- Hot-pluggability: They can be installed and removed without powering down the equipment, providing flexibility and ease of maintenance.
Addressing Common Questions
- What is the difference between 2.5GBASE-SR and 2.5GBASE-LR SFP transceivers?
The main difference between these two types of transceivers is their reach. 2.5GBASE-SR transceivers support a maximum reach of 2 km over MMF, while 2.5GBASE-LR transceivers can transmit data up to 10 km over SMF.
- Are 2.5G SFP transceivers compatible with all network equipment?
Yes, 2.5G SFP transceivers are compatible with a wide range of network equipment from major vendors. However, it is always recommended to check with the equipment manufacturer for compatibility.
- What are the considerations when choosing a 2.5G SFP transceiver?
The key factors to consider when choosing a 2.5G SFP transceiver are the required reach, compatibility with the network equipment, and the operating environment.
Conclusion
2.5G SFP transceiver modules have become an essential component of modern networking infrastructure. Their cost-effectiveness, high-speed performance, and long reach have made them a popular choice for data centers, enterprise networks, and telecommunications companies. As the demand for higher bandwidth connectivity continues to grow, 2.5G SFP transceivers are poised to play an even more significant role in the future of data communications.
