Most conventional LCs are unlocked via a clip on the plug. This mechanism restricts packing density in the patch panels. A gap must be maintained between the plugs or adapters, so that the clip is accessible and to enable unlocking.

The new LC-QR connector from R&M, on the other hand, has a push-pull mechanism integrated into the housing. It can be operated via the rear and the user no longer must grasp right to the front of the connector. Furthermore, the LC-QR can be locked and unlocked via the boot, and connectors and adapters can be packed more closely. In this way, the LC-QR provides a packing density of up to 240 fibers (or 120 ports) per rack unit. This translates into an unbelievable amount of 10,080 fibers in a conventional 42U cabinet.

The LC-QR was designed to suit a particularly high concentration of network connections and simple operation. With this in mind, we designed a textured boot to ensure easy access to and removal of the connector. It also allows for quick tool-less polarity reversal. Until now, when fiber optic patch cords were ordered, one had to choose whether to employ standard polarity (A-B) or to wire without crossover (A-A). Data centers often use both types of wiring. This means they must keep stock of both versions.

R&M’s LC-QR can be converted from A-B to A-A in just a few simple steps. This makes ordering and stock keeping easier. One only needs one type to enable configurations of both types of wiring on site. R&M has designed the LC-QR such that the polarity can be changed manually, even tuned plugs and APC version – a real innovation.

Of special interest is the industry-leading 1.4 mm cable diameter design that enables unmatched ease of management in high-density rack and panel configurations, as compared to legacy cords with diameters of 2 mm or more. And of course, it can be equipped with an R&MinteliPhy RFID-tag.
