Fiber Closure Sppliers Greentel Offer Closures

Posted By fiberclosure top     September 7, 2018    


Greentelftth introduction of the world's advanced level of Fiber Closure production lines and supporting the monitoring, testing equipment, only to focus on product development. As a true fiber closure manufacturer, greentelftth is driven by a mission to deliver the highest standard of product quality, performance, and customer value in the industry.

1. Basic Closures

At its simplest, a closure joins one length of fiber cable to a different length of the same type of cable. This is sometimes known as in-line closure or track joint. Added functionality is provided by a spur (or branch) joint which divides the cable into two ongoing parts - the main cable and a side or spur cable. There are also end of route closures where the cable is broken out into individual elements for customer or telco connection.

The earliest fiber closures were direct descendants of their copper cousins. The simplest in construction (but not to use!) were wrap-around heat-shrink products, most usually just in-line closures but sometimes branch joints. Although they could be made water resistant they had few other benefits (except low cost) and often required a skilled jointer to apply them.

2.Tube Distribution Closures

With the widespread adoption of blown fiber and cable systems which use multiple microduct bundles, tube distribution closures have become prevalent. As the name suggests these either create an in-line microduct track joint or, more commonly, branch off individual microducts to different destinations. Instead of fiber jointing occurring in the closure, individual microducts are joined together by purpose-made push fit connectors that in themselves are designed to be water tight. This has enabled the closure to be of simple design, without the need for expensive seals and is easily assembled in the field.

3.Dome Closures

Probably the most common type of closure is now the ‘dome’ closure, which comprises a base with cable port inlets, a stack of splice trays and a removable dome cover. The advantages are:

The format is easily sealed to IP68, yet the dome can be removed in seconds for re-entry.

Many configurations of base can be produced within the same overall footprint

By using different domes closures can be expanded to add in more splice trays.
