Fiber Optic Splicing Solutions

Fast, high performance methods for your single and mass fusion splicing applications

High performance fiber optic connectivity is now a critical component within every network infrastructure. This evolution has driven innovations in a range of areas, and fiber optic splicing is no different. Traditional methods of anaerobic epoxy connections for field-termination have been joined by a range of next generation splicing approaches that offer more flexibility and support your current and future termination needs.

It’s important to remember that there is no ‘single’ field termination connection method that suits every application, the diverse characteristics of both inside-plant and outside-plant environments requires taking an objective approach when selecting your preferred termination method to ensure you can save time and cost while optimizing your optical loss budget.

Fusion Splicing

Typical Applications: Carrier Networks, POP/MMRs, Video Networks, Enterprise.

Optical fiber fusion splicing has moved to become the preferred choice for many installers given the high performance connections that can be achieved utilizing this method. Fusion splicing forms a ‘welded’ joint between two optical fibers and provides a permanent, low loss, high-strength connection compared to mechanical splicing.

The recent introduction of splice on connectors provides a comparable alternative to field polished or mechanical splice connectors for those who prefer fusion splicing.

Mechanical Splicing

Typical Applications: Enterprise, Restoration

Mechanical splicing allows for two fibers to be joined in an alignment fixture using index matching gel. This method has been available for a number of years and continues to be popular as it offers fast, straight forward termination and results in limited waste as it requires less consumables than traditional epoxy/polish connector methods.
