It is a 25G Ethernet standard that utilizes a single channel wavelength of 850nm, which allows it to transmit data at speeds of up to 25 Gbps. The 25GBASE-SR module supports link lengths of up to 100 meters on OM3 and OM4 multimode fibers and up to 150 meters on OM5 multimode fibers. It is also backward compatible with 10GBASE-SR and 40GBASE-SR4 standards, making it ideal for use in existing networks. By utilizing the latest advances in optics technology, 25GBASE-SR can provide reliable and cost-effective solutions for today’s high-speed networking needs.
What is 25GBASE-SR and How Does it Work?
25GBASE-SR is an optical module that uses a multi-mode fiber (MMF) to transmit data at a rate of 25 gigabits per second (Gbps). It supports link distances of up to 100 meters, making it ideal for connecting devices within a data center. The SR in 25GBASE-SR stands for Short Reach, which refers to its ability to transmit data over short distances.
The 25GBASE-SR optical module uses a vertical-cavity surface-emitting laser (VCSEL) to transmit data over an MMF. The VCSEL emits light at a wavelength of 850 nanometers (nm), which is within the range of the MMF’s bandwidth. The MMF then carries the light signal to the receiver, which converts it back into electrical signals that can be processed by the network system.

Overview of the Different Types of SR Optical Modules:
There are different types of SR optical modules available on the market, including 25GBASE-SR, 10GBASE-SR, and 100GBASE-SR. Each of these optical modules provides high-speed connectivity over short distances, but they differ in terms of their performance and compatibility.
10GBASE-SR is an optical module that provides high-speed connectivity at a rate of 10 Gbps over a distance of up to 300 meters. It is part of the 10 Gigabit Ethernet (10 GbE) standard, which was developed to support the increasing bandwidth demands of data centers.
100GBASE-SR is an optical module that provides high-speed connectivity at a rate of 100 Gbps over a distance of up to 100 meters. It is part of the 100 Gigabit Ethernet (100 GbE) standard, which was developed to support the increasing bandwidth demands of data centers.
Functionality and Benefits of Using a 25GBASE-SR Module:
The functionality of a 25GBASE-SR optical module is similar to other SR optical modules. It provides high-speed connectivity over short distances, making it ideal for connecting devices within a data center. One of the benefits of using a 25GBASE-SR module is its high bandwidth capacity, which allows for the transmission of large amounts of data quickly.
Another benefit of using a 25GBASE-SR optical module is its compatibility with the existing MMF cabling infrastructure. This means that you can upgrade your network system to support 25 Gbps without having to replace your existing cabling infrastructure.
There are also some disadvantages to using a 25GBASE-SR optical module. For example, it is limited to short distances of up to 100 meters, which may not be suitable for larger data centers. Additionally, it requires a compatible MMF cabling infrastructure, which cost more.
One of the main benefits of using a 25GBASE-SR module is its low power consumption. This is because it uses a VCSEL to transmit data, which is a low-power device compared to other types of lasers. This makes it an energy-efficient option for data centers that require high-speed connectivity.
Another benefit of using a 25GBASE-SR optical module is its reliability. It uses advanced error-correction techniques to ensure that data is transmitted accurately and without errors. This helps to prevent data loss and corruption, which can be costly for data centers.
In addition, 25GBASE-SR optical modules are hot-swappable, which means they can be removed and replaced without having to power down the network system. This makes it easy to upgrade or replace faulty modules without causing downtime for the network.
How to Install a 25GBASE-SR Module in Your Network System:
Installing a 25GBASE-SR optical module is a straightforward process. Here are the steps to follow:
Turn off the network device that you want to install the module in.
Locate the appropriate slot for the module on the device. This may be marked as an “SFP+” or “QSFP+” slot, depending on the device.
Insert the module into the slot. Make sure that it is properly aligned with the slot and that the locking mechanism is engaged.
Connect the MMF cable to the module. Make sure that the cable is properly seated and that the connector is securely fastened.
Turn on the network device and verify that the module is working correctly. You can do this by checking the device’s status indicators or by using a network monitoring tool.
Conclusion:
25GBASE-SR optical modules provide high-speed connectivity over short distances, making them an ideal choice for data centers. They offer several benefits, including high bandwidth capacity, low power consumption, and reliability. If you’re considering upgrading your network system to support 25 Gbps, a 25GBASE-SR optical module is a good option to consider.
