摘要

Recently, fiber ribbon slotted core type cables are the most popular optical fiber cable for trunk lines or wiring facilities. Especially the 4-fiber ribbon is very popular. When branching off this 4-fiber ribbon to a user facility normally it is divided into two core units to be connected to the other optical fibers extending to different lines. However, dividing the cable into two core units and the connection work which follows is difficult. To solve these problems, we have developed the SZ-slotted Divisible 4-fiber ribbon which can easily he divided into two core units. A 4-fiber ribbon with 2× 2-fiber ribbons is laid side by side. 2-fiber ribbons are wrapped as an unit by a binding layer to prevent separation of individual core when dividing. The 4-fiber ribbons are accommodated in the Si slotted rod is superior in structure for dividing afterward. While the 4-fiber ribbon has not been used for optical fiber cables in cold districts where the temperature is below -20℃, the 2-fiber ribbon is used instead. However our durability test of our divisible 4-fiber ribbon cable in cold districts which were implemented under cooperation of Hotnet showed satisfactory durability.
