The Latest in Optical Data Links: 100GBASE-SR4 and Why You Should be Excited

What is a 100GBASE-SR4 Optical Module and What Does it Do?

An optical module is a device that converts an electrical signal into light and vice versa. It is typically used in networking devices to convert the data from an electrical signal to an optical signal and vice versa.

A 100GBASE-SR4 Optical Module is a type of optical module that can carry up to 100 Gigabytes per second of data. It uses SR4 modulation which has four different states, each state representing a different pattern in the transmitted light. This helps with error detection and correction.

100GBASE-SR4 is a standardized optical module that enables data transmission over long distances. It is mainly used for connecting two networks via an optical fiber. The 100GBASE-SR4 was originally developed to be a cost-effective solution for 10 Gigabit Ethernet, but it can also be used for connecting two networks via optical fiber.

What is a 100GBASE-SR4 Optical Module work principle?

The 100G optical module is also called an optoelectronic module. Optical modules are used in many devices such as telephone exchanges, computers, and routers. The 100GBASE-SR4 optical module works by using a laser to transmit the data. The laser is used to modulate data onto the optical fiber and then send it through a multi-mode fiber.

The 100GBASE-SR4 optical module work principle is based on the QSFP28 interface. This interface allows for a maximum data transfer rate of 100 gigabits per second (Gbps). The 100GBASE-SR4 optical module work principle uses a wavelength of 850 nanometers (nm) for transmitting data over fiber optic cable and 850 nm for receiving data over fiber optic cable.

The Advantages of the 100GBASE-SRSR4 Optical Module

The 100GBASE-SR4 optical module is a new generation of 100G optical modules. It has the following advantages: 100G optical modules are the latest development in data transmission technology. They provide higher bandwidth to support more data and faster speeds over long distances.

The 100GBASE-SR4 optical module is designed to be used in high-speed data centers, enterprise networks, and other applications that require a large amount of bandwidth. The 100GBASE-SR4 features an improved signal quality, lower power consumption, and reduced cost which make it an excellent choice for today’s high-capacity networks.

Is a 100GBASE-SR4 Right for You?

The 100GBASE-SR4 is a new generation of SFP optical modules. It provides data rates up to 10Gbps and is compatible with the IEEE 802.3ae 10GBASE-SR specification.

The 100GBASE-SR4 is designed for use in data centers, enterprise wiring closets, and other high-density environments where cost and power consumption are important considerations.

The 100GBASE-SR4 can be used for connecting servers or storage devices to switches or other devices in a data center or between racks inside an enterprise wiring closet. The module also can be used for interconnecting network devices located at different distances from each other on the same floor in an office building or campus environment. The module might not be appropriate for use as a connection between two network devices

In conclusion, the 100GBASE-SR4 is not a good fit for every application. If you are looking for a short-distance connection between two locations in your office and you need to connect at speeds up to 100 Gbps, then this module is perfect for you. But if you are looking for a long-distance connection that does not need high speeds, then this module is not the best choice.


After this article, we know that the 100GBASE-SR4 optical module is only suitable for short-distance data transmission, if you need to choose a long-distance transmission solution, then you may need other modules, like 100GBASE-LR4, etc. If you want to know more about 100GBASE-SR4, you can consult QSFPTEK via We specialize in manufacturing various types of optical modules for 10G and 40G and 100G optical modules.
