| Includes five distinct models in both flame retardant and non-flame retardant versions, each with flexibility built in for growing networks. They can effectively provide splice protection in nearly any environment, including aerial, underground or vault. They require no special tools or training, allowing for easy re-entry and re-configuration. |

| The LightLinker system is a full series of splice closures and trays used for housing, organizing and protecting single or mass fusion fibre splices. Completely modular in design, the system offers total flexibility to meet the evolving requirements of worldwide fibre optic networks. A full range of closure sizes, diameters from 76 - 241 mm (3- 9-1/2") in combination with lengths up to 914 mm (36"), gives systems designers multiple options when considering splice location options. And while smaller size closure would normally be considered optimal, larger LightLinker closures can be used in many cases to provide extra storage space for ribbon or buffer tubed fibre. |

The fibre Optic Closure 2179-CS is designed and developed based on the proven 3M sealing technology. It is made of plastic moulded parts and mastic sealing materials. Closing of the closure is simply done by the sliding latching mechanism. 2179-CS latching system provides short installation time and easy re-entry. There is no need for special tooling for closing and opening the closure.
It is suitable for the applications up to 48 single fibres, which can cover most of the applications in the fibre distribution networks like Fibre To The Home / Fibre To The Curb (FTTH/FTTC) Underground, aerial, pedestal or direct buried applications are possible with the closure. 2179-CS has chemical and mechanical resistance for all the application areas in the fibre networks. Can be used in butt or In-line configuration. |

BPEO Evolution is the new generation of fibre cable splice protection closure for transport, distribution and FTTH applications. The product range is designed to the high standard of original BPEO closures, with the ECAM mechanical cable entry sealing and with a new generation of organisers and trays called "BPEO Evolution".
Evolution organisers and trays were developed to permit single circuit management and to allow integration of splitters and other passive components into the closure. |
| Fibre Dome Closures |

3M™ FibrDome Closures protect fibre optic splices from the elements while providing fast and easy no-cost re-entry. These closures can be installed in above-ground pedestals, hand-holes, and mounted on poles and strands.
The FibrDome closure utilizes proven sealing technology and over 30 years of experience with copper protection. Fibre splices are enclosed in a polypropylene dome that is clamped together with a stainless steel latch and sealed with an O-ring. Pre-stretched tubing is slipped over the base of the closure and onto a gel sealing collar. Pulling the plastic rip cord shrinks the tubing to an air and water tight seal around the collar. No special tools, power supply or torches are required for assembly. To re-enter, simply pull the latch. |

| Designed to cost-effectively deploy aerial fibre networks. Weather-tight, single-piece aerial closure can be easily installed for new construction or maintenance situations and permits complete splice access after placement without the removal of the closure from the cable. This free-breathing closure (FBC) features a durable double-walled, blow-molded body that resists cracking or breaking even in the harshest environments. Maximum splice capacity is 144 for single and 432 for mass fusion. |

| This weather-tight aerial closure can easily be installed for new construction or maintenance situations. Proven, single-piece construction permits complete splice access after placement without the removal of the closure from the cable because it has two separate chambers: a distribution cable splice chamber and a drop termination chamber. Can handle up to 12 external or internal drop cable terminations. |
