Tight buffered fiber optic cable is produced as that fiber is sheathed by buffer material. The selection of top-quality fiber, the specific production equipment and the accurate design assure the performance of the product. To be more specific, a single-mode or multi-mode fiber with a tightly-coated secondary coating structure is called a tight buffered fiber or a tight-packed fiber, and is a double-over-plastic (PVC/PVDF) directly coated on a bare fiber (UV fiber). /LSZH/Hytrel), the outer diameter of the tight-fitting fiber is usually 0.6mm and 0.9mm. It is the basic component for manufacturing various indoor optical cables. It can also be used alone and twice coated with various materials. The tight-fitting fiber can be directly used as a pigtail for the connection of various optical active or passive components, the connection of instruments and terminal equipment, and the like.
GYDTA uses steel as the central strength member ensures good tensile resistance,and improves the bending performance. It has excellent moisture resistance ability:the loose tube is filled with grease to protect the fiber, APL tape prevent the water ingress, then the cable is completed with PE out sheath. It's suitable for aerial and duct application. Because of the good moisture resistance, it can also be used in cable trench. It has the loose tube structure with ribbon cable, which is surrounded by the APL tape. GYDTA is a good option for interoffice communication,outdoor access network.
GY-Outdoor optical cable for communication,X-Central tubular structure,T-Filled,W-Steel polyethylene bonded sheath with steel wire. GYXTW fiber optic cable, 250um, in a loose tube made of high modulus plastic. The tubes are filled with a water-resistant filling compound, mainly for the longitudinal water blocking of the fiber and the compactness of the fiber. The tube is wrapped with a layer of PSP longitudinally. Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape.
The structure of the self-supporting pre-terminated drop cable is based on the Butterfly cable, and a metal suspension unit is added. With the continuous extension of the optical fiber like the user end, in order to meet the different uses and requirements, and expand the use range of the butterfly-introducing cable, on the basis of the Pre-terminated Drop Cable, a derivative product of the butterfly-introducing has emerged, the most typical one being The Self-supporting Pre-terminated Drop Cable is introduced into the optical cable.READ MORE
"GY" means outdoor optical cable for communication, "F" means non-metallic reinforcing member, "T" means ointment filling structure, "Y" means polyethylene sheath. GYFTY is positioned in a loose tube made of a high modulus plastic. At the center of the core is a fiberglass reinforced plastic (FRP), and the loose tube (and the filling rope) is twisted around the central reinforcing core into a compact and round core with a gap in the core filled with a water-blocking filler. The outer core of the cable is extruded with a polyethylene inner sheath to form a cable.
The optical fiber unit, Pre-terminated Drop Cable, is positioned in the center.Two parallel Fiber Reinforced Plastics (FRP) are placed at the two sides.Then,the cable is completed with a black or color LSZH sheath. It is also called leather cable. It is a new type of user access optical cable. According to the application environment and laying conditions, the cable structure and various technical parameters are reasonably designed. The characteristics of indoor soft cable and self-supporting optical cable are collected. Special equipment is used in conjunction with imported precision mold production. It is the best candidate for FTTX network solution, and it is also suitable for users of other fiber-optic FTTO and FTTB networks. Because the cross-section is like a butterfly, it is called a butterfly cable. Both sides are reinforcing members in the leather line and optical fibers in the middle.
Planar lightwave circuit PLC splitter is a type of optical power management device that is fabricated using silica optical waveguide technology.It features small size,high reliability,wide operating wavelength range and good channel-to-channel uniformity,and is widely used in PON networks to realize optical signal power splitting. Bare PLC splitter is putting PLC splitter chip and input, output optical fiber array in a square metal tube, out with the diameter of 0.9mm or 250um bare fiber ,fiber can be welded, can also be processing various types of optical fiber connector. We provides whole series of 1*N and 2*N splitter products that are tailored for specific applications.All products meet "YD/T1117-2001 All optical fiber branching device technical conditions","YD-T 2000-209 PLC Integrated optical devices PLC optical power splitter"etc, and are certified by TLC for network deployment.
FTTH optical fiber terminal box, outdoor optical fiber terminal box is used in wiring connection between optical cable and optical communication equipment, through adapter in distribution box, optical fiber jumper leads optical signal, realize optical wiring function, and can meet the optical splitter placed to achieve spectral function.FTTH terminal box from Foclink is available for the distribution and terminal connection for various kinds of optical fiber system, especially suitable for mini-network terminal distribution, in which the optical cables, patch cores or pigtails are connected.
