The flexibility of optical cable, small external diameter, high density, big bandwidth, environmental protection and energy saving etc. are required specifically for computer room by the requirement applied
And develop.
Current most of outdoor optical cable is used in the method for factice for filling in cable core gap to prevent water and moisture from entering light
Cable and along optical cable longitudinal propagation.Although this method is very effective, there is also some following shortcomings, and some of which shortcoming pair
Optical cable in local loop is even more serious.These shortcomings have：
(1) weight that ointment adds optical cable is inserted in cable core, is unfavorable for installing, particularly optical cable is drawn into pipe
During road；
(2) factice for filling is possible to drip and enters tap points and cause added losses, and to reopen when safeguarding to connect
Head increase complexity；
(3) consistency problem may occur with other elements in optical cable (such as loose tube material, sheath material)；
(4) to take a significant amount of time to erase the ointment in optical fiber, fiber optic components and operation instrument, and clean when continuing
Solvent has the potential problems of harm health；
(5) factice for filling makes the outer layer non-metal reinforcement member and sheath imperfect bonding in optical cable, is installed when with traction chuck
It may tear sheath during optical cable；
(6) percent defective may be increased by producing the optical cable of factice for filling.Therefore need to study a kind of safe, stability
Preferable and long lifespan cable.
