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
Fiber optic media converter are generally used in the network environment where Ethernet cables cannot cover and must use optical fibers to extend the transmission distance. They are usually located at the access layer of broadband metropolitan area networks, and are widely used in various monitoring and safety projects. It is inevitably encounter some problems […]
fiber optic transceiver is a key component to the network performance, to maintain it requires attention to some details to avoid product damage and hurt to maintenance personnel.
The most common SM fiber connector color we encounter is blue type during installation work. When Comes to a passive optical network (PON), operator network or very large-scale data center, the green color APC fiber connectors are used more common. It is very important to understand the difference between the two fiber connector with different […]
Fiber Optic Media Converters Ethernet devices with cat5 or cat6 cable to fiber optic cable.extend the Ethernet signal over a much longer distance, how to check whether it is the converter problem when the equipment is not working?
