Fiber Optic

Speed is the defining characteristic of this system: Fiber Optic is the optimal connection technology whenever the highest data rates and fast, interference‐free transmissions are required. We deliver quality and stability – our high‐performance optical technologies can serve a wide and demanding range of applications.

Whether for particularly harsh environments, high mating cycles, or long transmission distances: ODU Fiber Optic is the ideal system solution for industrial outdoor use, medical technology, or standard applications in which speed and reliability are important.

FAQ about ODU Fiber Optic

What are the advantages of fiber‐optic transmission besides high data rates?

There are also other benefits, such as reduced weight, smaller cable options, and the fact that the signal (light) within the fiber is also impervious to electromagnetic interference since no electrical signal is transmitted.

What is the difference between ODU interface connectors and standard versions?

Standard interface connectors are designed for indoor use, mainly for data centers. ODU system solutions with Fiber Optic technology, on the other hand, meet the requirements for harsh environments, a high number of mating cycles, as well as IP protection – and can thus be used in a more versatile manner.

What is meant by "fiber only" and hybrid systems?

Fiber only“ refers to a purely fiber‐optic system solution that does not contain any copper contacts.

Hybrid means that the system can be simultaneously used for data (via optical or plastic fiber) and power or signals (via copper).

Are there different types of contact systems in the ODU connectors?

Yes, there are three different contact systems, each with different core properties.


Expanded Beam

  • Low loss levels even under harsh conditions  
  • Robust and reliable optical connection (less cleaning required)  
  • Contact system is rated for 100,000 mating cycles


Expanded Beam Performance

  • Fiber types: Singlemode and Multimode
  • Configurations: 2 to 12 fibers
  • Outstanding optical performance


Physical Contact  

  • Multimode and single‐mode versions available  
  • Up to 1,000 mating cycles  
  • Polymer Optical Fiber  


Polymer Optical Fiber  

  • POF system solutions for harsh environments  
  • High flexural strength (impervious to temperature fluctuations)  
  • Cost‐efficient optical connection for short transmission distances 
What’s the difference between Physical Contact and Expanded Beam?

Physical Contact refers to the direct contacting of the ferrule tips within the ODU connector. The end faces contact each other with a predefined spring force to ensure low‐loss light transmission.

Expanded Beam means that the light is expanded by means of a special lens in the contact system to extend the transmission range between the contacts. The end faces do not touch, making them more resistant to dirt and suitable for a higher number of mating cycles.

What does PC or APC mean?

PC stands for "Physical Contact" and describes a straight (0°),  polished end face of the fiber.

APC stands for "Angled Physical Contact" and describes the end face of the fiber, which is polished at an angle (8°).

Which fiber types does ODU use as standard?
  • Multimode: In multimode optical fibers which have a larger core (50µ), several light modes of the signal are transmitted. This means that more data types can be transmitted.
  • Singlemode: Unlike multimode, singlemode fiber optic cables have only one propagation mode. A single wavelength of light in the fiber core. This means there is no interference or overlap between the different wavelengths of light, which could alter your data over even greater distances, as is the case with multimode cables.
  • POF Polymer Optical Fiber: For simpler applications, the light signal is transmitted with POF (fibers made of special plastic) with a core size of the fiber of 980μm. The bandwidth and distances of the signal to be transmitted are limited here by the physical conditions.
Which ODU connectors are available as Fiber Optic system solutions?

Fiber Optic solutions are available for all main product series, including ODU MINI‐SNAP®, ODU MEDI‐SNAP®, ODU AMC® and ODU‐MAC®. We offer both pure fiber‐optic and hybrid versions.

Are Fiber Optic products offered as system solutions?

The technologies are designed as fully assembled Fiber Optic system solutions for the respective applications. To ensure a 100% error‐free connection, the entire system solution should always be based on fiber optics. A connector can only meet the requirements for the customer’s application in combination with the right cable.

What should be considered with regard to cleaning the products?

With our Fiber Optic range, cleaning is always very important to ensure good signal integrity. If dust or other particles reach the end surface of the contacts, the signal will either be blocked or transmitted at a reduced data rate. Therefore, it’s important to ensure proper cleaning of the components and to select the appropriate contact system for the respective applications. The corresponding cleaning instructions can be found here: Expanded Beam, Expanded Beam Performance and Physical Contact.
