ABCs of 100G QSFP28 SR4 Optical Transceiver Modules

The 100G QSFP28 SR4 optical module is an optical fiber module for high-speed data transmission, which is widely used in data centers and enterprise networks. It supports a transmission rate of 100 Gbps and uses four channels (four fiber channels) for data transmission. The module complies with the IEEE 802.3bm standard and is particularly suitable for environments with high bandwidth requirements, such as cloud computing, data center interconnection, and enterprise-level network construction. By using the standard QSFP28 interface, the 100G SR4 module enables high-density network deployment and is compatible with existing equipment.
How Does the 100G QSFP28 SR4 Optical Module Work?
The working principle of the 100GBASE-SR4 QSFP28 optical module is based on multimode fiber (MMF) and 4x25Gbps data transmission technology. Each channel provides a transmission rate of 25Gbps, and the total bandwidth of 100Gbps is achieved through 4 independent internal transmit and receive fiber channels. The module uses electronic optical conversion technology to convert electrical signals into optical signals, transmit them through multimode optical fibers, and then convert optical signals back into electrical signals through the optoelectronic converter at the receiving end. This 100G transceiver module is usually used for short-distance transmission, with a typical transmission distance of 100 meters (via OM4 optical fiber) or less.

FAQs
- What fiber types does the SR4 100G QSFP28 optical module support?
The QSFP28 SR4 optical module supports multimode fiber (MMF), and the common standards are OM3 and OM4 fibers. The maximum transmission distance supported is usually 100 meters.
- What is the difference between the 100G QSFP28 SR4 and other types of QSFP optical modules?
Unlike long-distance modules such as QSFP28 LR4, SR4 is suitable for short-distance transmission and is usually used for connections within a data center or within the same building. It uses multimode fiber, while LR4 uses single-mode fiber and is suitable for transmission distances of more than 10 kilometers.
- How to choose a suitable optical module?
When selecting an optical module, you need to choose it based on factors such as the bandwidth requirements of the network, transmission distance, and fiber type. If high-bandwidth transmission is required over a short distance, the 100G QSFP28 SR4 is an ideal choice. If the transmission distance is longer, you may need to choose a long-distance version (such as QSFP28 LR4).
4.Is the installation of 100G QSFP28 SR4 optical module complicated?
The installation process of 100G SR4 QSFP28 optical module is usually simple. You only need to insert the module into the slot of a switch or router that supports QSFP28 interface and connect the appropriate optical fiber.
