Fiber Optic Cabling Systems

Fibre optic cabling - Perfect in every detail

 

Comprehensive system solutions for structured fibre-optic cabling

Cabling systems from Rosenberger OSI are designed as comprehensive system solutions for structured fibre-optic cabling. All the components are optimally harmonised to guarantee outstanding reliability. As early as 1997, Rosenberger OSI was one of the first companies to look at the potential of parallel optics cabling. This pioneering technology is now a decisive factor for future-proofed IT infrastructures. What is more, we are not simply satisfied with standard products: Our fibre-optic cabling systems stand for: Maximum quality. Outstanding transmission values. Ease of handling.

 

Quality that convinces

  • Guaranteed identification and traceability
  • Traceable quality thanks to individual measurement reports
  • Certifications: in accordance with DIN ISO 9001 since 1995 and ISO 14001 since 2008
  • Premium Verification Programme (PVP) in the GHMT product and process audits by customers

Reduced loss values

With modern processes, optimised production processes and ongoing quality controls, we ensure the best possible products for high-end cabling. We deliver cable assemblies according to exact standards. And better than the norm: e.g. the insertion loss (IL) of our PURE quality for 50µm multimode is lower than the highest performance class specified in the standard IEC 61755-5 Ed. 1.0 CD Grade CM.

Ease of handling - “Plug & Play”

Quick, reliable installation of fibre-optic cabling thanks to factory-assembled plug & play systems. Pre-assembled, high-quality cabling components not only optimise data centre performance. Our fibre-optic cabling systems are easy to lay, extend and modify. They therefore help reduce maintenance and setup times, thereby helping to cut operating overheads.

 

Fibre-optic cabling for indoor, outdoor or universal use

 

A comparison of our fibre-optic cabling systems – which system best meets your requirements?

You will find the answer in our PreCONNECT® Fibre Guide - depending on your individual needs and in the light of the following criteria.
Where will the cabling system be used - indoors, outdoors or both? For what type of application - Duplex or parallel optic data transmission?
How long are the transmission distances? What fibre type and fibre quantities are needed? What is the preferred connector type?

PreCONNECT® Fibre Guide

All our fibre-optic cabling systems are also available in OM5 on request. Do you have any other questions? We will be delighted to advise you.

The quality features of PreCONNECT® Fibre-optic cabling

Our fibre-optic cabling systems are available in two quality features. This gives you the ability to define the quality of the FO connector surfaces according to your requirements. Simply decide on the required PreCONNECT® cabling system and choose your preferred quality level.

PreCONNECT® BASIC

Quality feature PreCONNECT® BASIC is our well-proven, high-grade, standards compliant product in terms of end-face geometry, defect, and cleanness, providing excellent IL and RL performance. 

Features:

  • Quick, reliable installation thanks to factory-assembled plug & play system
  • Harmonised modular components ensure end to end performance of the entire channel 
PreCONNECT® PURE

Quality feature PreCONNECT® PURE is our well-proven high-grade connector surface quality in terms of geometry, but with better scratch-image and even higher cleanness than BASIC.

= PreCONNECT® Basic Features

PLUS

Guaranteed protection against contamination and damage to the polished front surfaces of the connectors thanks to sealed connection interfaces.

The advantages to you:

  • Time savings during initial installation and commissioning due to the elimination of the need for cleaning
  • Outstandingly low insertion and return loss
  • Greatest possible transmission range

Any questions?

Here you will find answers to topics related to fibre-optic cabling.

What is special about the fibre-optic multimode standard?

The core diameter of the multimode optical fibre is either 50/125 µm or 62.5/125 µm. Multimode means that the fibre is able to transmit multiple light modes. There are at present four frequently used types of MM fibre, each of which has different properties: OM1, OM2, OM3 and OM4. These are used to propagate light of wavelength 850 nm - and less frequently also 1300 nm. Two fibres are needed for a full-duplex connection – one for sending and one for receiving the signal. As things are in 2019, this permits a serial data flow in one direction at a speed of 50 Gigabits per second. 100/200/400 Gigabit Ethernet over multimode fibres uses a different technology, namely “parallel optic transmission”.

What do OM3 and OM4 mean – and what about OM5?

The OM3 fibre made it possible to transfer 10 Gbit/s of data over acceptable transmission lengths of up to 300 m for the first time at a relatively economical cost. 40 Gigabit and 100 Gigabit Ethernet are also supported up to a length of 100 metres.

In 2010, ISO/IEC 11801 defined a OM4 fibre with an improved effective modal bandwidth at 850 nm. The maximum transmission length of an OM4 fibre is 550 m at 10 GBit/s. 100 Gigabit Ethernet is also supported up to a length of 150 metres.

The OM5 fibre is the latest addition to the family of 50-µm multimode fibres. However, special multimode wavelength multiplexing transceivers are needed to make the use of these fibres with their extended transmission range effective. OM5 does not bring with it any improvement in the modal bandwidth or increased maximum transmission distances for existing optional 850-nm transmission protocols.

Singlemode fibres – and are these compatible with MM fibres?

At 9 µm, the fibre core of single-mode cables is considerably smaller than that of multimode fibres. For this reason, only a single light mode can be propagated in the core. The benefits are very low signal attenuation values and runtime delays. This means that singlemode fibres can cover greater distances without the need for any signal amplification or preparation. 

Singlemode and multimode cables are basically not compatible with one another and therefore cannot be connected together.

What is the LC connector all about?

The LC connector is a high-performance fibre-optic connector for singlemode and multimode fibres and is approximately half the size of the SC connector. As a result, it can provide twice the packing density. It has a push-pull locking mechanism and is configured for 500 to 1,000 mating cycles. The mean insertion loss is only 0.2 dB, and the return loss is 55 dB. 

The LC connector is available as a simplex connector or as a duplex variant. In data centres, multiple duplex connectors are combined to form multi-fibre connection systems. Using four LC duplex connectors, it is possible to establish eight connections, while six duplex connectors permit twelve connections. 

MTP® / MPO push-on connectors – definition and applications

The abbreviation MPO stands for “Multi-fibre Push-on Connector”. It is a push-on connector for multi-fibre cables consisting generally of 6, 8, 12 or 24 fibres. The MPO push-on connector is often referred to as an MTP® connector. This is a registered trademark of US Conec. 

The MPO/MTP® push-on connector can be used both for parallel optical applications such as Infiniband, for example, with data rates of up to 120 Gb/s as well as for Ethernet protocols with 40/100/200/400 Gb/s over OM3, OM4 and OS2 multimode fibres. Thanks to the modular nature of MPO/MTP® cabling systems, the effort involved in installing, adapting and maintaining a structured communications cabling system is considerably reduced.
