Firestore Fiber Optic Cable

Fiber Optic Cable
A fiber optic cable is a network cable used for long distance, very high performance data networking and telecommunications. It contains one or more glass fibers to carry light. A fiber optic cable functions as a “light guide”, which guides the light from one end of the cable through to the other end. According to different transmission mode of light, there are two common types of fiber optic cable: single-mode and multimode optical fiber cable. Single-mode fiber uses very thin glass strands through which only one mode can be transmitted. It carries higher bandwidth and gives you a higher transmission rate, but it’d better be used in a long distance and it costs more. Multimode optical fiber can offer you high bandwidth at high speeds in a shorter distance than single mode fiber.
Fiber Optic Patch Cable
Fiber optic patch cable, also called fiber jumpers or fiber patch cord, is a fiber optic cable limited at either end with connectors which allow it to be fast and conveniently linked to an optical switch or other equipment in the fiber optic network, and it is also a basic and important parts in optical communications. The most commonly used fiber optic patch cables are usually terminated with LC, SC, ST, and FC fiber optic connectors.
Fiber Optic Pigtails
Fiber optic pigtail is a fiber cable with only one side having fiber optic connectors while leaving the other side no connectors, therefore the connector side is able to be linked to the equipment and the other side can be spliced with optical cable fibers. Fiber optic pigtails are used with fiber optic management equipment like ODF, splice closures and cross cabinets, which are also used to achieve accurate mounting for precision alignment of fiber optical components. In general, there are several commonly used fiber optic pigtail types, including SC, FC, LC, ST, MU, E2000 and MTRJ.
MTP/MPO Trunk Cables
MPO/MTP trunk cable is mainly composed of two parts, MPO/MTP connectors and the fibers. A MPO connector is the industry for “multi-fiber push on”, while the MTP connector is a high performance MPO connector with multiple engineered product enhancement to improve optical and mechanical performance when compared to MPO connectors. A single MPO/MTP connector can suspend the combination of 4, 8, 12, 24, 48 fiber ribbon cables. The MTP/MPO trunk cables, which are constructed from loose tube and gel-filled indoor/outdoor rated cables, are applied to interconnect cassettes, panels or ruggedized MPO/MTP fan-outs, spanning MDA, HAD and EDA zones. What’s more, MTP/MPO trunk cables greatly reduce the installation and maintenance costs with their efficient plug and play architecture.
MTP/MPO Harness cables
A MTP/MPO harness cable, also named MTP/MPO fan-out cable or MTP/MPO breakout cable, is a fiber optic terminated with MTP/MPO connectors on one end and MTP/MPO/LC/FC/SC/ST/MTRJ connectors on the other end. The connectors on each end of the fiber cable could be different. Thus, the MTP/MPO harness cable is usually divided into MPO/MTP-MPO/MTP harness cable, MPO/MTP-Secure Keyed LC harness cable and MPO/MTP-Stardard LC harness cable. MTP/MPO harness cables are designed for high density applications which requires high performance and fast installation. MTP/MPO harness cables are ideal for connecting high speed switches populated with higher rate transceiver. As data communication technology develops fast, it is essential to transit from discrete commercial connectors to MTP/MPO.
Multimode Fiber Cables
Multimode fiber cable is a type of fiber optic cables, which is mostly used for communication over short distances, such as in a working building or on a campus. Multimode fiber cables are generally divided into four common types: OM1, OM2, OM3 and OM4, each of type is deployed in different applications. The equipment used for communications over multi-mode fiber cables is less expensive than that for single-mode fiber cables. And the transmission speed and distance limits of multimode fiber cables are 100 Mbit/s for distances up to 2km, 1Gbit/s up to 1000m, and 10Gbit/s up to 550m. Because of its high capacity and reliability, multimode fiber cables are often used for backbone applications in buildings.
Single-Mode Fiber Cables
Single-mode fiber cable is a glass fiber with a diameter of 8.3 to 10 micron which has one mode of transmission. Single-mode fiber cable has a relatively narrow diameter, through which only one mode will be transmitted. Because of this, the number of light reflection created as the light passes through the core decreases, lowering attenuation and creating the ability for signal to travel further. Single-mode fiber cable offers a higher transmission rate which make it possible to be used in long distance. And it has a much smaller core than multimode fiber cable, which can virtually eliminate any distortion that might result from overlapping light pulse, providing the least signal attenuation and the highest transmission speeds of any fiber cable type. However, it also costs more.
Simplex Fiber Patch Cable
Simplex fiber patch cable is a type of patch cable used for the connection of two network device ends. As for the meaning of simplex, also known as single strand, this cable is with only one thread of fiber optic glass inside core, and simplex fiber patch cables are with one single outer jacket. Because simplex fiber optic cable consists of only one fiber link, there is only one connector at either end of the cable. Simplex Fiber Patch Cable is ideal for use in office LAN connection, patch cord, pigtail and internal point-to -point links where frequent handling is likely(e.g. data cabinet equipment rooms, user outlets.
Duplex Fiber Patch Cable
Duplex fiber patch cable is a type of fiber patch cable, which has two fibers either single-mode or multimode. Duplex fiber patch cable can be regarded as two simplex cables having their jacket conjoined by a strip of jacket material. Unlike simplex fiber patch cable, duplex fiber patch cable has two connectors at each end of the cable which make it possible for the cable to be used in applications where data needs to be transferred bi-directionally. One fiber transmits data one direction; the other fiber transmits data in the opposite direction.
