SFP (Small Form Factor Pluggable) is a compact, hot-swappable transceiver module that converts electrical signals into optical signals (and vice versa), enabling long-distance communication between devices. One of the main advantages of SFP modules is their hot-swappable nature, which allows them to be inserted or removed without powering down network devices.
QSFP-DD (also known as QSFP56-DD) is a dual-density quad-channel small form factor pluggable package, a new type of high-speed pluggable module package that complies with the IEEE 802.3bs and QSFP-DD MSA standards. This package has 8 electrical interfaces, achieving a data rate of up to 25Gb/s per channel through NRZ modulation technology, enabling 200G network transmission; and up to 50Gb/s per channel through PAM4 modulation technology, enabling 400G network transmission. It is suitable for high-performance computing data centers and cloud networks.
In some network scenarios, as services expand and develop, the demand for bandwidth grows exponentially, but network infrastructure development cannot keep up with this growth. Infrastructure construction, especially the laying of fiber optic resources, is time-consuming, labor-intensive, and resource-intensive. Therefore, for a long time, networks will face the problem of fiber optic resource shortages, which have become core bottlenecks restricting further increases in network bandwidth. BiDi (Bi-Directional, single-fiber bidirectional) optical modules were developed precisely to solve this problem.
The SFP-25G-LR optical module (SFP28 1310nm 10km) is a high-performance long-distance data communication module. It features an SFP28 package, 25G data rate, 1310nm wavelength, a transmission distance of 10km, an LC interface, and supports operating temperatures from 0-70 degrees Celsius. The SFP-25G-LR optical module boasts stable performance, low power consumption, and strong compatibility, making it ideal for use in 25G Ethernet switches, routers, network interface cards, and storage network devices.
The 10G SFP+ dual-fiber optical module is a small, pluggable optical transceiver with a dual-fiber bidirectional design. It uses two independent optical fibers to complete signal transmission (Tx) and reception (Rx) respectively, ensuring the stability and reliability of signal transmission.
