The advent and development of fiber optic communication technology has brought a revolutionary change to the communications industry. Nowadays in the world, about 85% of communication services via optical fiber transmission, long haul netw…

Fiber optic splitter (optical splitter) is also known as “non-wavelength selective optical branching device”. It is a fiber optic device used to achieve a particular band optical signal power splitter and redistribution.Optical splitter ca…

Variable optical attenuator (VOA) has a wide range of applications in optical communication, and its main function is to reduce or control the optical signal.The basic characteristics of fiber optic network should be Variable, especially w…

The current invention relates generally to computer-based industrial control systems, such as microprocessor control of digital and analog functionality, and much more particularly relates to methods and apparatus for calibrating, monitori…

As IPTV, triple play, VoIP and other new telecommunications services rise, people find that IP-bearing agreement business has rapidly spread in most regions of telecommunications and fiber optic networks.IP-based packet-based carrier netwo…

Optical WDM networks are networks that deploy optical wdm fiber links where each fiber link carries multiple wavelength channels.An exciting Optical Network (AON) is definitely an optical wdm network which supplies end-to-end optical paths…

Fiber optic transceiver is an indispensable network data transmission equipment. What is fiber optic transceiver? What is the structure of fiber optic transceivers? What is the role of fiber optic transceivers in the data dissemination pro…

Before the introduction of CWDM multiplexer, it is necessary to mention the CWDM technology.Originally, the term “coarse wavelength division multiplexing” (CWDM) was fairly generic, and meant a number of different things. In general, these…

With the recovery of optical fiber communication industry and the development of FTTX, the spring of fiber optic splitter market is coming.There are two types of optical splitter, which are Fused fiber splitter and PLC splitter. PLC splitt…

Filter-based Wavelength Division Multiplexer (Filter WDM, or FWDM) is based on the mature membrane filter technology, with a wide channel bandwidth, low insertion loss, high channel isolation degrees and high environmental stability and re…

An optical add-drop multiplexer (OADM) is a device used in wavelength-division multiplexing systems for multiplexing and routing different channels of light into or out of a single mode fiber (SMF). This is a type of optical node, which is…

An optical attenuator is a device used to reduce the power level of an optical signal, either in free space or in an optical fiber. The basic types of optical attenuators are fixed, step-wise variable, and continuously variable.Application…

Optical amplifier is an optical communication system device. It amplifies an optical signal directly, without converting an optical signal into an electrical signal.Erbium-doped fiber amplifier (EDFA) is the first successful optical amplif…

Optical splitter is suitable for a fiber optic signal to be decomposed into multi-channel optical signal output.Role of optical splitter (1) It divides out a main light source into 1-N optical path. (2) It synthesizes 1-N optical path into…
