Patent number: 9459421Abstract: Described are cable designs adapted for aerial installations wherein the cable comprises a bundle of multifiber tight buffer encasement units, with a conformal thin skin containment layer surrounding the bundle. The multifiber tight buffer encasement units have an acrylate compliant inner layer that protects the fiber and minimizes stress transfer to the fiber; and a hard, tough acrylate outer layer that provides crush resistance. The thin skin containment layer provides cable integrity with a minimum of added size and weight. The thin skin containment layer encasement is encased in an outer protective jacket.Type: GrantFiled: July 27, 2012Date of Patent: October 4, 2016Assignee: OFS FITEL, LLCInventors: Carlton Gibbs, Mark G Graveston, Jason Pedder, Peter A Weimann

Patent number: 5550947Abstract: Apparatus for use in interconnecting optical fibers comprises a shelf 12 slidably mounted between a retracted position (FIG. 2) and an extended position. Housings 48 for locating fiber interconnections are mounted on the shelf 12. A plurality of tubes 22 are connected to respective further tubes 26, which are connected to the housings 48, by tube connector 30. The tubes 22 and 26 guide optical fibers to the housings 48. Each tube 22 has a substantially helical configuration over a portion 24 of its extent located behind the shelf 12 to accommodate sliding movement of the shelf.Type: GrantFiled: June 5, 1995Date of Patent: August 27, 1996Assignee: Pirelli General plcInventors: Laurence Llewellyn, Mark G.
