Full-dry skeleton tight-buffered fiber optic cable

Classified according to the distance of the fiber to the user. FTTX can be divided into 4 modes: FTTC, FTTN, FTTP and FTTH. In the FTTH access mode, the feeder section and distribution section of the access network currently use three types of optical cables: loose cable, tight cable, and skeleton ribbon cable.

Based on the characteristics of several typical optical cables, it is decided to use a full-dry skeleton tight-buffered optical fiber cable.

Full-dry skeleton tight-buffered fiber optic cable

Miniaturization solutions for optical cables emerge in an endless stream, such as air-blown micro-cable technology, tight-buffered fiber optic cable technology, and FTTX-specific skeleton technology. Rigorous process design and manufacturing standards ensure the performance of all-dry skeleton tight-buffered optical fiber cables.

All-dry skeleton type tight-buffered optical fiber cable, the optical fiber ribbon in the skeleton optical cable is replaced with a tight-sleeved loose fiber, which reduces the wrapping of the optical fiber with the resin, which saves the cost and facilitates the construction and splicing, that is, overcomes the optical fiber ribbon The shortcomings of the skeleton optical cable also overcome the oil pollution of the loose tube structure, the large size of the loose tube when the optical fiber is integrated, and the excellent mechanical properties that the indoor optical cable does not have. No ointment filling, no compatibility and hydrogen evolution problems, good lateral pressure resistance, superior moisture resistance, convenient connection, easy to split a single fiber and other obvious advantages.

In the special skeleton slot of the all-dry skeleton type, put the loose fiber in the tight sleeve with appropriate tension, and control the excess length of the optical fiber in the skeleton slot. The geometric design of the skeleton groove improves the freedom of the fiber. Dry water blocking tape and aluminum tape are longitudinally wrapped to block moisture to prevent moisture intrusion. The open cable ensures fast and efficient longitudinal sectioning of the optical cable during the construction process. All the designs fully take into account the needs of customers, and are qualified after a number of tests.

The all-dry skeleton tight-buffered optical fiber cable provided by ZR Cable is fully suitable for the construction requirements of FTTH. The all-dry structure does not cause pollution during the construction process, provides support and guarantee for the operating environment of optical communication, and is more in line with environmental protection requirements; the tight-buffered optical fiber has the characteristics of high strength and toughness, and the skeleton provides the optical fiber with sufficient lateral pressure resistance, etc. Mechanical properties provide a guarantee for the safety of communication lines.

Longitudinal open cable is set in the full-dry skeleton type tight-sleeve optical fiber cable, which is quick and convenient to open and cut, and eliminates the optical fiber damage caused by the construction level problem when the conventional loose sleeve is longitudinally cut.

The compact DP fiber splitter box saves costs, saves space to the greatest extent, and is economical and convenient to maintain. The loose fiber in the tight sleeve can be easily taken out from the skeleton slot, and with its good bending resistance, it is convenient to keep in the fiber distribution box, and it is convenient to be spliced ​​with other types of access optical cables. The on-site optical fiber branch connection is convenient and fast, and the simple construction mode has been fully recognized by the front-line construction personnel.

Through the cooperation between operators and optical cable manufacturers, as a new type of optical cable suitable for access network, full-dry skeleton tight-buffered optical fiber cable has been successfully applied in FTTH access network engineering with its own advantages. The main features are convenient construction, simple and easy expansion, saving the overall construction cost, and ensuring the network security of the wiring section. All-dry skeleton tight-buffered fiber optic cable will also become a preferred solution for fiber-to-the-home for other major operators.
