DefinitionDense Wavelength Division Multiplexing (DWDM) is an associate extension of optical networking. DWDM Technology devices mix the output from many optical transmitters for transmission across one fibre. At the receiving end, other DWDM Technology device separates the combined optical signals

Definition:A transceiver is a device comprising both a transmitter and a receiver which are combined and share common circuitry or a single housing. When no circuitry is common between transmit and receive functions, the device is a transmitter-receiver. The term originated in the early 1920s. Simil

PON is Passive Optical Network. This is a telecommunications technology that implements a point-to-multi-point architecture, in which unpowered Fiber Optic Splitters are used to enable a single optical fiber to serve multiple end-points such as customers, without having to provision individual fiber

Definition:A gigabit interface converter (GBIC) is a standard for transceivers, commonly used with Gigabit Ethernet and fibre channel in the 2000s.[citation needed] By offering a standard, hot swappable electrical interface, one gigabit port can support a wide range of physical media, from copper to

Definition:An optical fiber connector terminates the end of an optical fiber, and enables quicker connection and disconnection than splicing. The connectors mechanically couple and align the cores of fibers so light can pass. Better connectors lose very little light due to reflection or misalignment

Definition:The Institute of Electrical and Electronics Engineers Standards Association (IEEE-SA) is an organization within IEEE that develops global standards in a broad range of industries, including: power and energy, biomedical and health care, information technology and robotics, telecommunicati

Definition:Layer 3 switching is solely based on (destination) IP address stored in the header of IP datagram (see layer 4 switching later on this page for the difference). The difference between a layer 3 switch and a router is the way the device is making the routing decision. Traditionally, router

Definition1000BASE-T (also known as IEEE 802.3ab) is a standard for Gigabit Ethernet over copper wiring. Each 1000BASE-T network segment can be a maximum length of 100 meters (330 feet), and must use Category 5 cable or better. Auto negotiation is a requirement for using 1000BASE-T.The device perfor

Can we interconnect the SFP, SFP+ and XENPAK/X2? Is it possible to connect X2-10GB-LR to 10GBASE-SR with 4-5 meter patch cord? And can LC-SC patch cord connect X2-10GB-SR between SFP-10G-SR? These questions were asked by Cisco users? They are also common questions often asked by Cisco clients and us
