PreCONNECT® PURE FO cabling system

PreCONNECT® PURE: sealed coupler interfaces


Guaranteed protection against contamination during installation & reduced loss values

PreCONNECT® PURE is a milestone in the development of high-end IT cabling for data centers. It eliminates two uncertainty factors that are critical to overall performance in day-to-day operations: Contamination and the real-world loss budget.

This gives you certainty in the planning of transmission paths and allows you to implement more connections per channel. PreCONNECT® PURE will help keep your data center running smoothly over the long term.


The advantages of PreCONNECT® PURE at a glance:


Guaranteed protection against contamination and damage to the polished front surfaces of the connectors during initial installation and commissioning.


Outstandingly low insertion and return loss


Greatest possible transmission range


Uncertainty factor: Contamination

By their very nature, the optical contacts integrated in PURE connectors make it impossible for contamination or damage to occur during installation.

  • Thanks to the newly designed interface with an innovative locking mechanism, each channel can be snapped in without difficulty from behind into the subpanels of the SMAP-G2 housing.
  • On the patch side, the LC duplex connectors are sealed with protective caps, keeping channels clean even if they are not used for a long time.
  • The factory sealing also protects against unwanted opening and operating errors.

Uncertainty factor: actual loss budget

PURE connectors have an extremely low, guaranteed insertion loss as measured in real-world applications.

  • Insertion and return loss better than IEC 61755-5 Ed. 1.0 CD Grade Cm (multimode)
  • Guaranteed maximum insertion loss of 0.4 dB (application limit, LC multimode 50 µm)
  • Mean insertion loss = 0.15 dB (LC multimode 50 µm)

PURE quality permits reliable planning of data center cabling

PreCONNECT® PURE gives you certainty in the planning of transmission paths and allows you to implement more connections per channel. Thus, for any given loss budget*, PreCONNECT PURE permits up to twice as many connections per channel as with IEC-specified cabling. In addition, the high quality of Rosenberger OSI OM4 fibers allows greater channel lengths.

* In relation to 1.0 dB insertion loss, a channel length of 150 m and a loss budget of 1.54 dB according to original Fibre Channel 16 Gb/s OM4 specification.

Areas of application for this high-performance cabling system include infrastructure cabling and IT room cabling in data centers.
PURE quality is now available for all fiber-optic cabling systems using LC, MTP® or MU Duplex connectors.

Rosenberger OSI will be delighted to help you define technical guidelines to enable you to optimize the management of your specific process flows.
