As the best OEM fiber optic cable manufacturer, JTOPTICS provides a wide range of optical fiber cables. Bulk fiber optic cable comes in different types, depending on where it will be installed.
With the fast development of fiber optic communication technology and the trend of FTTX, indoor fiber optic cables are more and more required to be installed between and inside buildings. Typical indoor fiber optic cable types include GJFJV, GJFJZY, GJFJBV, GJFJBZY, GJFDBV and GJFDBZY. Compared with outdoor use fiber cable, indoor fiber optic cable experience less temperature and mechanical stress, but they have to be fire retardant, emit a low level of smoke in case of burning. And indoor fiber cables allow a small bend radius to make them be amendable to vertical installation and handle easily.
Most indoor fiber optic cables are tight buffer design, usually they consist of the following components inside the cable, the FRP which is non-metallic strengthen member, the tight buffer optical fiber, the Kevlar which is used to further strength the cable structure, making it resist high tension, and the cable outer jacket. The trend is to use LSZH or other RoHS compliant PVC materials to make the cable jacket; this will help protect the environment and the health of the end users. Usually the single mode indoor fiber optic cables are installed between the buildings where the distance is more than 100 meters, while multimode indoor fiber optic cables are used shorter distance connections. We supply SMF and MMF indoor fiber cables with various structures for different applications.
Outdoor fiber optic cables are made to protect the optical fiber to operate safely in complicated outdoor environment. Most outdoor fiber cables are loose buffer design, with the strengthen member in the middle of the whole cable, the loose tubes surround the central strength member. Inside the loose tube there is waterproof gel filled, whole cable materials used and gels inside cable between the different components (not only inside loose tube) will help make the whole cable resist of water.
Typical outdoor fiber optic cable types are GYTS, GYTA, GYXTW, GYTA53, GYTY53 and GYTC8S (also called Figure 8 cable) GYTS, GYTA and GYXTW outdoor fiber cables are used for aerial and duct applications, GYTA53 and GYTY53 are used for direct buried, GYTC8S the figure 8 outdoor fiber optic cable is used mainly for aerial. We supply various kinds outdoor use fiber cables including both armored type and not armored type.
We supply following Optical Fiber Cables:
250μm Bare Fibers
250μm bare fiber means the bare optical fiber with a soft plastic coating whose diameter is 250 microns. It consists of a central core which carries the light signal, using a cladding material whose diameter is 125 microns.
900μm Tight Buffer Fibers
900μm Tight Buffer Fibers are basically 250μm coated fibers covered with a thick layer of hard plastic, which adds protection. It just adds a 900μm hard plastic layer over the 250μm soft plastic coating.
Large Core Glass Fibers
Large Core Glass Fibers are made from silica glass, which have an extremely large core compared with the optical fiber for tele-communication. They are excellent for transmission of high density optical energy from ultraviolet rays to near infrared rays.
A simplex fiber optic cable has only one tight buffered optical fiber inside the cable jackets. Simplex fiber optic cables are typically categorized as interconnect cables and are used to make interconnections in front of the patch panel.
Duplex cable consists of two fibers, usually in a zipcord (side-by-side) style. Multimode and Singlemode duplex fiber optic cables are used for two-way data transfers.
The Distribution Indoor Cable tight-buffered design allows cables to be installed in intra-building backbone and inter-building campus locations without costly transitions between cable types.
Indoor/Outdoor Fiber Cable delivers outstanding audio, video, telephony and data signal performance for educational, corporate and government campus applications. With a low bending radius and lightweight feature, this cable is suitable for both indoor and outdoor installations.
Loose tube fiber optic cables, such as All-Dielectric Loose Tube Cables, Gel-Filled Loose Tube Cables, Double-Jacket Loose Tube Cables, Central Loose Tube Cables. They offer the best protection in an outdoor environment. The loose tube design provides stable performance over a wide temperature range and is compatible with any telecommunication grade optical fiber.
Fiber Breakout Cables
Fiber Breakout Cables are made of several fiber cables bundled together and are often used for conduit runs, riser and plenum applications. They can be easily divided into individual fiber lines as each fiber is individually reinforced.
Ribbon Fiber Cables
Ribbon Fiber Cable has recently emerged as a primary cable choice for deployment in campus, building, and data-center backbone applications where ﬁber counts of more than 24 are required. The cable design characteristically consists of 12 to 216 ﬁbers organized inside a central tube.
LSZH Fiber Optic Cables
Low smoke zero halogen or low smoke halogen free (LSZH) is a typical cable jacketing material classification which composed of thermoplastic or thermoset compounds that emit limited smoke and no halogen when exposed to high sources of heat. LSZH fiber optic cable jacket is more fire-resistant compared with common PVC jacketed cables. With LSZH compound, Low smoke zero halogen cable reduces the amount of toxic and corrosive gas emitted when super heated, meanwhile the material burns to ash so it eliminates the risks in the event of a fire in the industrial environment.
Armored Fiber Optic Cables
Armored Fiber Optic Cable is used by the military, industrial applications as in petrochemical, industrial plants including nuclear and utilities are installed by direct burial in areas where rodents are a problem. The armored fiber cable construction provides additional crush and rodent protection, and this means the armored cable is conductive, so it must be grounded properly.
FTTH Fiber Optic Cables
FTTH Fiber Optic Cable is a kind of special curved optical fiber, which providing greater bandwidth and enhanced network transmission characteristics. This cable replaces the standard copper wire and can carry high-speed broadband services integrating voice, data and video.
Figure 8 Aerial Cables
Figure 8 self-supporting aerial fiber optic cables consist of an optical fiber core and integrated stranded steel messenger. They are used for campus-type environments, aerial links self-support or duct underground service for long runs between buildings.
Plastic Optical Fibers
Plastic optical fiber (POF) is an optical fiber made out of plastic rather than traditional glass. Traditionally PMMA (acrylic) is the core material, and fluoridated polymers are the cladding material. With very large diameter, POF cable is easy to run along skirting boards, under carpets and around tight corners.
