1.FTTH Indoor Cable
FTTH (Fiber To The Home), as its name suggests it is a fiber optic directly to the home. Specifically, FTTH refers to the optical network unit (ONU) mounted on home users or business users, is the optical access network application type of closest to users in optical access series except FTTD(fiber to the desktop).
There are 5 main advantages of FTTH:
First, it is a passive network, from the end to the user, the intermediate can be basically passive;
Second, the bandwidth is relatively wide, long distance fits the massive use of operators;
Third, because it is carried business in the fiber, and there is no problem;
Fourth, because of its relatively wide bandwidth, supported protocol is more flexible;
Fifth, with the development of technology, including point-to-point, 1.25G and FTTH have established relatively perfect function.
2. Indoor Fiber Optic Cable
Indoor optical cable is classified according to the using environment, as opposed to outdoor fiber optic cable.
Indoor optical cable is a cable composed of fiber optic (optical transmission medium) after a certain process. Mainly by the optical fiber (glass fiber is as thin as hair),plastic protective tube and plastic sheath. There is no gold, silver, copper and aluminum and other metal, fiber optic cable generally has no recycling value.
Indoor fiber optic cable is a certain amount of fiber optic forming to cable core according to a certain way, outsourcing jacket, and some also coated layer of protection, to achieve a communication line of light signal transmission.
Indoor cable is small tensile strength, poor protective layer, but also more convenient and cheaper. Indoor cable mainly used in building wiring, and connections between network devices.
3. Outdoor Fiber Optic Cable
Outdoor fiber optic cable, used for outdoor environment, the opposite of indoor fiber cable.
Outdoor cable is a type of communication line to achieve light signal transmission, is composed of a certain amount of fiber optic forming to cable core according to a certain way, outsourcing jacket, and some also coated with outer protective layer.
Outdoor cable is mainly consists of optical fiber (glass fiber is as thin as hair), plastic protection tube and plastic sheath. There is no gold, silver, copper and aluminum and other metal cable, generally no recycling value.
Outdoor cable is greater tensile strength, thick protective layer, and usually armored(wrapped in metal). Outdoor cables are mainly applied to buildings, and remote networks interconnection.
4.Fiber Optic Patch Cable
Fiber optic patch cable, also known as fiber jumper, used to connect from the device to fiber optic cabling link. Fiber jumper has a thick protective layer, generally used in the connection between the fiber converter and Fiber Termination Box. Commonly used fiber jumpers include: ST, LC, FC and SC.
Single-mode fiber patch cable: General single-mode fiber jumper is colored in yellow, connector and protective sleeve are blue; long transmission distance.
Multi-mode fiber patch cable: General multimode fiber jumper is colored in orange and some in gray, connector and protective sleeve are beige or black and the transmission distance is short.
Fiber optic jumper connector interpretation:
SC Connector: square fiber optical connector;
FC Connector: round with thread;
ST Connector: similar to BNC;
LC Connector: transceiver separation structure;
MT-RJ Connector: square, one with double fiber;
PC Connector: direct contact;
APC Connector:8 degree tilt angle of contact surface;
UPC Connector: arc contact surface.
In the event you working in telecommunications industry, acquiring thorough information about fiber optic patch cables is essential. Fiber optic cable are used for linking the apparatus and components in the fiber optic network ,they are with various types of fiber optic connector types. The fiber optic patch cord types are classfied by the fiber optic connector types. For example,we name LC fiber patch cable since this cable is to use LC fiber optic connector. You will find PC,UPC,APC type fiber patch cord, they’re different as a result of polish of fiber connectors. Fiber optic patch cables are available with ST SC LC FC connectors.Fiber optic patch cables may be split into different types according to fiber cable mode, cable structure, connector types, connector polishing types and cable sizes. However nowadays I would like to based on fiber connectors to introduces the normal kinds of fiber patch cable.
Common Forms of Fiber Patch Cable:
SC Fiber Optic Patch Cord
SC fiber optic patch cable is one of the earliest type and something of the very most commonly used fiber optic cable, it is simple to use and value saving, SC fiber cable is widely uesed in fiber optic networks. SC fiber patch cable is by using zirconia sleeve and plastic housing. Oahu is the standard fiber optic cable assemblies, with simplex, duplex patch cords and standard pigtails.
The SC fiber optic patch cord was invented by the Japanese company NTT. It really is probably the most popular fiber optic patch cords. SC fiber optic patch cord features low priced , simplicity along with good durability, SC fiber optic patch cords is with a locking tab about the cable termination, it’s a push and pull type fiber optic connector.
FC Fiber Optic Patch Cord
FC fiber optic patch cords are with FC fiber optic connectors ,the industry screw type connection. FC fiber optic patch cords were quite definitely popular previously ,but people have a tendency to use LC and SC to switch FC more and more. It’s the standard fiber optic cable assemblies, with simplex, duplex patch cords and standard pigtails.
The FC fiber optic patch cable comes in both singlemode and multimode versions, and it is fully intermateable with NTT-FC products. Both smf and mmf versions FC fiber optic patch cord have a zirconia ceramic ferrule with pre-polished PC profile and convex spherical end.
ST Fiber Optic Patch Cord
ST fiber cable connector features a bayonet-style housing along with a long spring-loaded ferrule support the fiber. They are available in both multimode or singlemode versions. Horizontally mounted simplex and duplex adapters are available with plastic or metal housing. It is the standard fiber optic cable assemblies, with simplex, duplex patch cords and standard pigtails.
ST fiber optic patch cords standard was created by AT&T. this sort of cable is with straight tip type terminations. there is only simplex ST fiber optic patch cords with no duplex ones.These days ST fiber optic connectors are generally having a metal housing ,nevertheless, there are plastic housing ST fiber connectors, more and more people often use metal housing ST. ST APC fiber optic patch cord are also available.
LC Fiber Optic Patch Cord
The LC fiber optic patch cable is by using a little form factor (SFF) connector and is perfect for high density applications.LC fiber optic patch cord connector includes a zirconia ceramic ferrule measuring 1.25mm O.D. having a PC or APC endface, and provides optimum insertion and return loss. It is the standard fiber optic cable assemblies, with simplex, duplex patch cords and standard pigtails.
LC will be the short kind of Lucent Connector, LC fiber patch cord connector can be a push and latch structure, with plastic housing and accurate 1.25mm ceramic ferrule. LC type is a well-liked type of small form fiber optic patch cord which decrease the space and it’s also popular for densely installation.
