Fiber Optic Communication

MTP/MPO fiber cable designed for a higher bandwidth transmission. It has two types, the one type is 12-fiber for 40G data transmission while the other type is 24-fiber for 100G data transmission. MTP/MPO fiber cable can meet the huge demand for more bandwidth and more space efficiency of data centers and ever-expanding server clusters. In this article, MTP/MPO connector, MTP/MPO trunk cable and MTP/MPO harness cable will be covered. What IS MTP/MPO Connector? The letters MTP/MPO stand for “Multiple-Fiber Push-On/Push-of”. MTP/MPO connector is designed for multi-fiber application. The MTP/MPO connector is manufactured specifically for multi-fiber ribbon cable. Furthermore, it can be divided into different types of female-female, male-male and female-male connectors. The male connector has metal guide pins to ensure fiber alignment when mating while female connector has no pins. A female connector is also known as a jack, outlet, or receptacle. This types of connector attached to a ...

It is known to all that fiber optic cable is made of glass or plastic that mainly used for transmitting information. Fiber optic cable can be divided into many types according to different classification principles, such as source, mode, usages... In this text, we would mainly introduce simplex and duplex fiber optic cable as well as their differences. Simplex Fiber Optic Cable A simplex fiber only consists one single strand of glass of plastic fiber. Simplex signals are sent in one direction. It is much like what we said “one-way-street”. If a signal is transmitted from device A to device B over a simplex fiber optic cable, it cannot return from device B through the same cable. For example, we receive signals from radio station but never send signals to it. Thus, it is used for applications that only require one-way data transfer. Simplex fiber is most often used where only a single transmit and receiver line is required between devices or when as multiplex data signal is used....

A fiber patch cord is a length of fiber cable fitted with LC, SC, MTRJ or ST connectors at each end. Fiber jumpers also come in hybrid varieties with one type of connector on one end and another type of connector on the other. Jumpers are used in the same manner as patch cords, to connect end devices or network hardware to the structured cabling system. Pigtail is a type of fiber cord, and in the the following text, the general information and types of pigtail will be provided. Information About Fiber Optic Pigtail Being different from fiber optic patch cord, fiber optical pigtail is a cable ended with fiber connectors at only one side of the cable while the other side without any connector (bare fiber). The connector side used for connection to the equipment while the bare fiber is melted with optical fiber. So the difference between a patch cord and a fiber optic pigtail lies in the two ends of the cable. Sometimes, we could change the patch cord into a fiber optical pigtail for...

Almost all modern optical transceivers utilize two fibers to transmit data between switches, firewalls, servers, routers, etc. One fiber is dedicating to receiving data from networking equipment while the other fiber is dedicating to transmitting data to the networking equipment. A new optical transceiver technology is now available that allows transceivers to both transmit and receive data to/from interconnected equipment through a single optical fiber. This technology first emerged about 7 years ago and had led to the development of Bi-Directional transceivers, or BiDi transceivers for short. The Bi-Directional Small Form Factor Pluggable (BiDi) is a compact optical transceiver module which is used in optical communication for both telecommunications and data bidirectional communications applications. It interfaces a network device mother board (for a switch, router or similar device) to a fiber optic or unshielded twisted pair networking cable. It is a popular industry format sup...

Small Form-Factor Pluggable (SFP) is designed to meet Multi-Source Agreement (MSA), 1 to 2.5 Gigabit Ethernet, Fibre Channel, and other communication standards to ensure network equipment compatibility. SFP transceivers are available with a variety of form factors, which allow users to select the appropriate transceiver for each link to provide the required optical reach over the available optical fiber type. It is used for both telecommunication and data communication. SFP has many types, such as 100BASE SFP, 1000BASE SFP, BiDi SFP... we would mainly introduce CWDM SFP, DWDM SFP and their differences in this text. CWDM SFP Extended from wavelength division multiplexing(WDM), Coarse Wavelength Division Multiplexing (CWDM) is used to increase the bandwidth of an optical fiber by multiplexing several wavelength onto it. Using 18 channels with wavelengths between 1270 nm and 1610 nm, it improves the transmission speed a lot. A CWDM SFP transceiver is a hot-swappable input/output devi...

Data communication and network technology have been developed in recent decades. With the expanding of networks, enterprises and vendors have been looking for a perfect solution to collect and store the data. Scalability, reliability and flexibility are their perpetual pursuit for their networks and data centers. Aimed at big data environments., Extreme X770 Series Switches meet a perfect need for all these requirements. This text will provide the some basic information about Extreme X770 Series Switches, especially for the transceivers that can be used in it. Introduction to Extreme X770 Series Switches Extreme X770 series switches are purpose-built top-of-rack switches designed to support 10 Gigabit Ethernet-enabled servers and emerging 40 Gigabit Ethernet-enabled servers in enterprise and cloud data centers. X770 series helps optimize new server deployments by supporting 40GbE ports or using breakout cables and/or fiber to support 10GbE ports to start the transition to the new...

Around 1980s, Internet traffic was increasing prominent as the unceasing popularity of the Internet equipment. A call for a higher demand of communication capacity was higher and higher than ever before. Data, video and voice signals crowd transmission systems that had ample space just a few years ago. The communications industry needs room to breathe. This is just an exactly time to upgrade the capacity and enhance the speed in fiber-optic technology. By sending signals at 16 different wavelengths through each of four pairs of optical fibers, Project Oxygen ( a project of a well-known company of fiber-optic technology) researched and developed a technology which can carry 640 gigabits per second (Gbit/s) across whole oceans. The technology that makes this new bandwidth possible is called wavelength division multiplexing, or WDM. It represents the second major fiber-optic revolution in telecommunications. The definition and two common types of WDM (CWDM and DWDM) will be provided in t...
