摘要： The present invention's optical cable is provided with optical fibers, a forming pipe for housing the optical fibers, a sheath provided around the forming pipe, and at least one pair of rip cords embedded in the sheath. The forming pipe is formed of a plurality of tapes so that it is dividable along its longitudinal direction. When dividing the optical cable, the rip cords are pulled to tear open the sheath, and the already split forming pipe is divided while staying adhered to the respective parts of the sheath. As a result, the division of the sheath and the forming pipe is carried out in one stroke, so that the optical fibers inside the forming pipe can be exposed easily and quickly.

The single mode fiber has a first cladding region with a uniform refractive index, a core region with a refractive index higher than that of the first cladding region, and a second cladding region including at least four air hole regions placed in the first cladding region. Optimization can be achieved by making the distance from the center of the core region to the air hole regions equal to 2-4.5 times the core radius, and the air hole radius equal to or greater than 0.2 times the core radius. It is preferable the core radius be 3.2-4.8 μm, the relative index difference of the core region from the first cladding region be 0.3-0.55%.

摘要： An optical connector is provided where an biasing device 26 which biases a ferrule 24 having an optical fiber 22 secured thereinside and a tip end face 23 which has been polished, in a tip end face 23 direction, is located to the rear of a connection mechanism 25 for connecting the optical fiber 22 on the ferrule 24 side and a separately inserted optical fiber 22a, at a rear end side of the ferrule 24 opposite to the front end face 23. The connection mechanism 25 has a construction which uses a mechanical splice, and is opened and closed by a release member inserted into an insertion opening 39 which is opened along an alignment axis direction. Hence the opening and closing operation does not interfere with the biasing device 26, so that operability is improved. Moreover, for this type optical connector there is provided an optical connector housing 21 which accommodates the ferrule. With this optical connector housing 21, by merely inserting the ferrule, the connection mechanism 25 for connecting the pair for optical fibers at the rear end side of the ferrule, and the stop ring 27 accommodating the connection mechanism 25, then assembly can be simply performed so that workability in assembling the optical connector is improved.
