Joint closure OPGW has been developed for using with OPGWs (OPtical Ground Wires) for jointing max. 48 fibres. The closure can be used as a direct and branching joint closure for OPGWs and as for terminating OPGWs at the end pole to non-metallic duct or buried cables.
The metal optical cable splice closure is made of aluminum alloy with perfect seal. It features in high mechanical strength, good airtight and anti-corrosive. Having been sealed with sealing ring and silicone, it could be opened, expansed, fixed, and connected repeatedly. It's suitable in aerial, piping, direct buried or in manholes.Compare with Plastic Closure, Metal Closure has many obvious advantages as mechanicalstrength, leak tightness and corrosion resistance. It's usually used for OPGW.
Suitable for bunchy & ribbon fibers.
Aerial
Metal joint box is made up of aluminum alloy, especially suitable for the protection of fiber cable joint under the high voltage electric field.
Metal joint box bears the excellence of high mechanical strength, good airproof performance, outstanding corrosion resistance and long service life. It can be used more than 25 years.
With excellent environmental applicability, reliability and waterproof, it can be fully met the requirements of the life of the optical communication systerm.
Easy to operate, optical fiber splicing loss is not affectedx by the stress, the transmission properties of the optical fiber.
Connector box in the optical fiber fixed on the tower and the connector box fixed is convenient, fast and strong. It also can be instailed on the tower. the concrete pole.
The splice, reinforced by hot-melting & hot-shrinking bushing., and the excesss length of fiber optic cable are accommodated in laminated way.
