PreCONNECT® PURE: Reliable planning of data center cabling
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:
PreCONNECT ® PURE
Uncertainty factor: contamination
§ § Integration of optical contacts in the LC-Duplex interfaces: ruling out contamination during installation
By their very nature, the optical contacts integrated in PURE interfaces make it impossible for contamination or damage to occur during installation. The LC-Duplex interface is sealed at the factory. You just snap it into the back of the front panel.
Your advantages at a glance
§ § Guaranteed parameters for unused channels until they are actually used § § Factory-sealed to prevent improper opening and handling
§ § Visual quality of ferrule end faces significantly better than IEC 61300-3-35 § § Quick, tool-free mounting with simple snap-in on the back of the panel § § Complete system consisting of trunk cables, patch cables, SMAP-G2 panels and racks
Uncertainty factor: loss budget PURE connectors have an extremely low, guaranteed insertion loss – not just in each-to-each tests, but in real-world applications. This gives you certainty in the planning of transmission paths and allows you to implement more connections per channel.
The PURE effect Twice as many connections and 15 meters more channel length *

* 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 Gbit/s OM4 specification.
§§ Insertion loss and return loss exceeding IEC 61755-5 Ed. 1.0 CD Grade Cm (Multimode) §§ Guaranteed maximum insertion loss of 0.4 dB (application limit, LC Multimode 50μm) § § Mean insertion loss = 0.15 dB (LC Multimode 50μm)
§ § Multimode and Singlemode
PreCONNECT® PURE is the first infrastructure cabling system based on OM4 being awarded a ”6 connector channel certification” for 40/100GBE and 16 GFC by GHMT (test report no. P3568a-14-D).
PreCONNECT® PURE will help to keep your data center running smoothly over the long term. But that’s not all. Read the following pages to learn about details and additional features.

Studies have shown that about 50 % of all network errors are caused by cabling problems. Of these, most involve contamination of fiber-optic cable connections, improper patching or even damage arising from patching. PreCONNECT ® PURE eliminates these causes from the start. §§ PURE trunk cables have preassembled PURE interfaces instead of conventional connectors §§ The optical contacts integrated in the interfaces are factory-tested for perfect optical quality and absolute cleanliness before the seal is applied §§ The connection does not have to be opened during installation; thanks to the new interface design, the complete unit can be snapped into the panel from behind §§ On the patch side the LC-Duplex interfaces are sealed with protective caps, preventing contamination even if the channels are not used for a long time. The warranty permits opening of seals and patching only by certified personnel (see also page 14/15, Services) In this way PURE not only ensures maximum data transmission over long distances, it saves time and costs by at least 15 %, because on-site acceptance tests and cleaning are unnecessary.
Insertion loss “Application limit” versus “Production limit” „Anwendungs-Grenzwert“ vs. „Produktions-Grenzwert“ An increase in transmission speed always means a reduction in the maximum permissible attenuation of multimode links. In high-end applications it is therefore essential to keep the insertion loss of fiber-optic connections as low as possible. To impress customers, cable manufacturers often quote the so-called production limit value, which is measured using reference couplers and connectors. But this value is of no relevance to actual practice, in which standard components with varying specifications are involved. For this reason Rosenberger OSI always quotes the so-called application limit value for PURE. This value applies to any combination of connectors, and it’s guaranteed. The value is 0.4 dB*, which is 0.2 dB better than the highest performance class specified in IEC 61755-5 Ed. 1.0 CD Grade Cm (see also page 6). The mean* insertion loss (IL) measured for PURE components is well below this, at 0.15 dB (see “Overall process capability” chart). This gives you a big safety margin from the application limit value. In actual practice even better values are achieved.

Installation: tool-free and easy
Overall performance:
PURE trunk cables are preassembled with LC-Duplex interfaces at both ends and sealed. Thanks to the newly designed interface with an innovative locking mechanism, each channel can easily be snapped from behind into the part front plates of the SMAP-G2 panels.
IEC 61755-5 Ed. 1.0 CD Grade Cm versus PURE
Comparison of maximum channel lengths*
The performance parameters for fiber-optic connections are set forth in the IEC 61753 and 61755 standards, which define grades. The highest performance class for multimode fibers is IEC 61755-5 Ed. 1.0 CD Grade Cm, which specifies a maximum insertion loss (IL) of 0.6 dB for 97 % of the connections and a minimum return loss (RL) of 20 dB. PreCONNECT ® PURE significantly exceeds both of these values:
150 m for IEC 61755-5 Ed. 1.0 CD Grade Cm
165 m for PreCONNECT ® PURE

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 elongated channel lengths (see illustration at right).

Every connection between two optical fibers can impede the propagation of light in the channel. To minimize insertion loss it is therefore essential for the fiber ends to meet exactly and for the end faces to have as few imperfections (scratches and defects) as possible. By exercising the utmost care in manufacturing we achieve visual quality results for our PURE interfaces that are well above the requirements of IEC 61300-3-35.

PURE interfaces are guaranteed to be absolutely clean all the way to completion of trunk cable installation. But what happens when they are to be connected? The moment the seal is removed and the protective caps are taken off for connecting a patch cable, the end faces of the fibers can be soiled or damaged if the connector is improperly handled. For this reason our warranty for insertion loss in PURE connectors is valid only if patching is carried out by Rosenberger OSI Services or certified service providers.
