CWDM Coarse Wavelength Division Multiplexing System is favored by operators for the Metropolitan network because of its low cost, convenient use, flexible system design , high reliability ect.
Wavelength division multiplexing equipment is particularly important in metropolitan area network construction especially long-distance OTN optical transmission network，. DWDM dense wavelength division multiplexing equipment has long-distance, high-bandwidth transmission capabilities; While lower cost can choose CWDM coarse wavelength division multiplexing equipment . How to choose the right wavelength division multiplexing equipment to build a cost-effective optical […]
Brief introduction about the SM TO MM media converters and its advantages.
DWDM is widely used in network upgrade and expansion in various fields for fiber backbone construction. how to solve the problem when there is some problems?
CWDM a low-cost WDM transmission technology, can provide optical relay, network security, mode conversion, wavlength conversion, various signal transmission to hundreds kilometers and network upgrade and expansion
Dense wavelength division multiplexing refers to an optical fiber data transmission technology, which uses the wavelength of the laser to transmit data within the fiber according to bit parallel transmission or string line transmission. DWDM is an important part of the optical fiber network. It allows IP, ATM, and synchronous optical network/synchronous digital sequence (SONET/SDH) […]
For XFP fiber optical modules, the functional failures usually means transmitter failure and receiver failure and usually it is raised by Optical port pollution and damage, ESD injury
A Gigabit Ethernet Passive Optical Network (GEPON) system is usually consisted with an OLT at the service provider’s central office and a number of ONUs or ONT near end users and fiber splitters. the optical distribution network (ODN) is used during the transmission between OLT and ONU/ONT.
WDM provides supper large capacity and upgrade the network smoothly without interrupting existing fiber, reduce the fiber lines to save cost and upgrade the network based on previous investment
