There’s More Inside Your Splice Closure than You Think

As fibre is being pushed deeper into the OSP network and technologies grow more sensitive to performance-eroding contamination, the variety of sealing technologies used to protect the fibres inside the closures have evolved.
Until very recently, there were three main types of seals: heat shrink, rubber seals (grommets) and thermoplastic elastomer (TPE) gel. Recently, the scientists developed a fourth technology—silicone gel—that adds critical capabilities and performance features una
