We know that optical modules can be divided into single-mode optical modules and multimode optical modules are usually marked on the module. Single mode to SM, for long-distance transmission, fiber color is yellow; multi-mode is MM, usually used for short-distance transmission, fiber color is orange

Most users feel puzzled about the compatibility of SFP and SFP+, and the real point that puzzles them is if the SFP module will work when plugging it into the SFP+ slot. For lots of engineers, this is also an issue that hard to get a clear answer. In this condition, this post will bring you to concl

Nowadays, with the rapid development of science and technology and the continuous improvement of user‘s needs, 40G applications in the communications industry are becoming more and more widely, at the same time, servers, switches, optical modules and other devices are also upgrading, the solutions f

WDM transceiver means wavelength-division multiplexing transceiver and this is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths of laser light. This technique enables bidirectional communications over one strand of fiber, a

Definition:An optical fiber (or optical fibre) is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair. Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in

Introduction:New technologies generate great excitement, but sometimes older technologies continue to serve important needs. An example of such a technology is 100BASE-FX. Although 100BASE-FX was developed in the mid-1990s, it is still in use today, 10 years later, when we also have Gigabit and 10-G

Definition:The XFP (10 Gigabit Small Form Factor Pluggable) is a standard for transceivers for high-speed computer network and telecommunication links that use optical fiber. It was defined by an industry group in 2002, along with its interface to other electrical components, which is called XFI.SFP

Definition:Small form-factor pluggable (SFP) is a specification for a new generation of optical modular transceivers. The devices are designed for use with small form factor (SFF) connectors, and offer high speed and physical compactness. They are hot-swappable.Compatibility It is possible to design

Definition:The Quad Small Form-factor Pluggable (QSFP) is a compact, hot-pluggable transceiver used for data communications applications. It is used to connect switches, network, computers and servers distances of 10km. QSFP transceivers are designed to support Serial and supported by many network c
