Fibre Optic Connectors

In today's data-driven world, the demand for high-speed data transmission is greater than ever. Fibre optic technology provides the backbone for innovation across countless critical sectors, from medical diagnostics to global telecommunications. For engineers and system designers, the reliability of every component is paramount. LEMO specialises in designing and manufacturing high-performance fibre optic connectors that ensure flawless signal integrity and data transmission in the most demanding environments. Our commitment to Swiss engineering excellence guarantees a connectivity solution that you can depend on when performance is non-negotiable.

Our high-performance 
fibre optic connector solutions

LEMO provides a comprehensive portfolio of fibre optic connectors, terminators, and tooling to meet the rigorous demands of modern applications. We understand that a one-size-fits-all approach is insufficient for the complex challenges you face. This is why we offer a range of solutions designed for specific performance criteria, ensuring uncompromised optical performances for your system.
 

Singlemode and multimode Datacom fibre solutions
 

We offer ultra compact butt-joint termini in PC or APC polishings. These fibre optic contacts, combined with our Push-Pull locking and IP68 sealing, offer a compact and ergonomic solution for many applications such as Datacom links in demanding environments (vacuum, medical, outdoor), deployable telecommunications networks, test and measurement, fibre optic sensing like FBG (Fibre Bragg Gratings) and distributed sensing and many other. 
 

Hybrid electrical-fibre connectors (SMPTE)
 

We engineer solutions that combine fibre optic and electrical contacts within a single, compact housing – ideal when space or ergonomics are critical. These all-in-one connectors deliver both power and high-speed data transmission with ease of use. The broadcast industry has long adopted such hybrid solutions through the LEMO SMPTE 3K.93C dedicated series. 



Speciality fibres with large core or special optical parameters
 

We offer a wide range of possibilities to interconnect special fibres, including large-core glass fibres up to 1500 µm, small-core fibres, or non-standard cladding diameter and even plastic optical fibres. These integrations typically require close collaboration with our customers to fully understand specific technical and ergonomic requirements, whether for medical catheters, spectroscopy, illumination, or laser delivery application

LEMO Fibre Optic Connectors Cable Assembly

Guaranteeing optical performances

Fibre optic connector performance strongly depends on cable assembly quality, as poor polishing can degrade overall performance. LEMO partners with its customers or certified VARs to offer its fibre optic connectors as fully cabled solutions. This approach allows us to control every step of the manufacturing process using top industry-standard equipment, ensuring guaranteed optical quality in every application. We integrate and connect your systems — from telecom connectors (such as LC, ST, FC, SC, etc.) — to ensure reliable signal transmission even in the most demanding environments.

Broadcast, telecommunications, and data infrastructure


The flow of data underpins modern society. LEMO connectors are integral to the infrastructure that makes it possible. In broadcasting, our hybrid fibre connectors are the standard for transmitting high-definition video signals. For telecoms, broadband, and datacentre networking, we provide high-density solutions like style connectors that enable more data in less space, ensuring the performance and scalability of the network.

Medical

 

Our connectors are lightweight, ergonomic, and resistant to sterilisation processes like autoclaving. In medical applications where failure can compromise patient safety, you need absolute reliability. We provide compact, high-performance solutions for surgical devices, diagnostic equipment, and patient monitoring systems. The robust design, a hallmark of Swiss engineering, ensures flawless performance and signal integrity even after repeated sterilisation cycles, guaranteeing equipment longevity in demanding clinical environments. 

Semiconductor Test & Measurement


Our products offer high reliability, precision, repeatability, and high-frequency performance essential for accurate and reliable measurement instrumentation. When your data integrity is paramount, the quality of every component matters. LEMO connectors provide a stable and precise connection, minimising signal loss and ensuring consistent performance in the most demanding environment, over mating cycles. This allows you to trust your measurements in laboratory research, field data acquisition, and quality control, where precision is the ultimate benchmark.

Defence & Aerospace, and UAV
 


We deliver rugged, compact, and lightweight solutions that address the critical Size, Weight, and Power (SWaP) requirements of modern military and avionics systems. In these harsh environments, subject to extreme vibration, shock, and temperature fluctuations, performance is non-negotiable. Our connectors ensure the unwavering reliability of communication, navigation, and surveillance systems. Their robust construction and secure locking mechanisms guarantee secure data integrity, providing the durability needed for mission-critical operations.
