A Detailed Look at Fibre Optic Connectors 

What are fibre optic connectors?

Fibre optic connectors are specialised components used to terminate or join the ends of optical fibres, enabling fast and efficient communication within a network.  

They are designed to securely align the fibre cores so that light signals can pass through with minimal loss or disruption. This precise alignment is essential for maintaining high-speed data transmission and overall network performance.

Common types of fibre optic connectors include LC, SC, and MPO/MTP, all of which are widely used in data centres, telecommunications systems, and industrial networking environments due to their reliability and ease of use. 

Why do connectors become faulty?

When connectors are damaged or faulty, this can significantly impact network performance. Problems may include intermittent signal outages, complete loss of signal, or high insertion loss, which refers to an excessive reduction in signal power as it travels through the assemblies.

These issues can disrupt communication systems and reduce efficiency. Fortunately, in most cases, such faults can be resolved through proper inspection, cleaning, repair, or full re-termination of the affected connectors. 

There are five key reasons why fibre optic connectors may become faulty, including: 

1. Contamination from dust, dirt, or oil which can block or scatter the light signal, reducing performance
2. Physical damage to the outer connector which can cause the fibre to misalign 
3. Any damage across the length of the fibre optic loom, in which it becomes damaged, affecting signal transmission 
4. Cut, bent or crushed cables leading to signal loss or breakage 
5. A damaged harness can compromise the stability and protection of the fibre connection

Alker repairs and replaces fibre optic connectors

Our team can evaluate damaged harnesses or assemblies and identify repair needs. Or for situations when fibre optic harnesses are integral and can’t be removed, we’ll provide on-site analysis, anywhere around the world, to carry out emergency on-site repairs.

There are several solutions we offer when repairing and considering how to support a client in protecting the in-service life of the connectors terminated to assemblies. This includes: 

• Sacrificial cables – these sit in front of connectors, absorbing damage so the asset or bulkhead remains protected 
• Sacrificial adaptors – a small, replaceable connector interface that sits between a fibre optic cable and a device. The sacrificial adaptor absorbs damage, protecting the fibre optics and attached assets 
• Toolkits – we provide inspection and cleaning kits along with training to ensure all on-site personnel can maintain the fibre optics. Regular maintenance and careful handling can help prevent damage to ensure reliable operation

Once repaired or replaced, we’ll offer the option to armour your assemblies to help future-proof assemblies and attached assets against damage from extreme conditions and challenging environments.

This method is fast-becoming the gold-standard solution to help extend the in-service life of any asset they’re connected to.
