LEVITON LM-RDT I/O CMP Category 6A Cable
Product Information
The LM-RDT I/O CMP is a versatile cable that can be easily routed in various locations requiring a transition between two types of cable. It has a dual- rating of CMP (Communication Plenum) and CMX-Outdoor, making it suitable for wet environments, plenum air spaces, and limited outdoor usage. The cable jacket is highly impervious to water and chemical-resistant, ensuring seamless installation.
Technical Specifications
- Dual-rating: CMP & CMX-Outdoor
- Waterproof and chemical-resistant jacket
- Designed for wet environments and plenum air spaces
INTRODUCTION
LM-RDT I/O CMP is a Category 6A cable designed to withstand a wide range of environments common to slab-on-grade installations. The cable’s flexible PVDF jacket allows it to be routed easily through underground conduit, plenum air spaces, and short exposed outdoor runs within the building footprint. By using the practices outlined in this guide, the cable can also be installed in conduits that may occasionally experience water ingress when conduits are designed to properly drain the water ingress.
Because the cable does not contain a water blocking gel, it is critical to protect the cable ends and jacket during installation. This guide will provide several options for protecting the cable ends from water ingress during installation using the provided kit. The cable jacket must remain unabraded during installation in order to prevent water ingress from negatively impacting cable performance.

APPLICATION ENVIRONMENTS
Transition Points Within Building
This product’s dual-rating (CMP & CMX-Outdoor) allows it to be routed
easily throughout a range of locations that typically require a transition
between two types of cable. Because the jacket is highly impervious to water,
chemical-resistant, and CMP rated, it can seamlessly pass-through wet
environments and plenum air spaces—simplifying installation. 
Limited Outdoor Usage
Although LM-RDT I/O CMP is not designed to be a replacement for outside
plant cable, it is suitable for certain outdoor applications. The cable
carries a CMX Outdoor rating, which means that it has been verified for both
sunlight resistance and cold impact. This makes it suitable for short outdoor
runs where the cable is exposed to the elements—e.g., being mounted to the
side of a building in order to support an outdoor wireless access point. If
mounting the cable to an external wall, it is important to use appropriately
sized cable clamps and assure that connection points are protected by suitably
rated enclosures for the environment. Drip loops should be used in order to
impede the infiltration of water into the building. The cable is not self-
supporting, and thus requires lashing and messenger strands for aerial
installations. Aerial installations must be performed in accordance with
Chapters 6 and 7 of BICSI G2.2-22. Furthermore, the cable is not designed for
direct burial.
INSTALLATION PREP
Because this product is a gel-free cable, the leading end must be protected
from water ingress during installation using one of the methods described in
Section 3.1.
Ensure conduit is installed per BICSI OSPDRM & TIA-758.
There are three methods of protecting the cable end from water ingress. All
are valid methods and can be used based on the availability of equipment. The
preferred method is 3.1.
- • Method #1 – Heat gun required (3.1)
- • Method #2 – Lighter required (3.2)
- • Method #3 – Vinyl electrical tape only (3.3)
- Total prep time is estimated to be 2 minutes per end following the methods below
- Methods #1 and #2 produce the smallest prepared end OD
- Use shrink tube provided with each reel of cable
- If additional shrink tube is required, please use Digi-Key Part Number A014B-4-ND or equivalent
Method #1 – Heat Gun Required
- Begin preparation by sliding a 2.5” long piece of shrink tube 1” onto the cable end
- Heat the shrink tube with a heat gun until it is constricted around the cable and the portion beyond the cable is reduced to its minimum diameter. Rotate the cable to assure that all sides of the tubing are shrunk.
- Once the shrink tube is cool enough to touch, fold it back and wrap with vinyl electrical tape until the tape extends ~1/2” beyond the base of the shrink tube. Failing to tape beyond the base of the shrink tube could result in it being pulled off during installation.
Method #2 – Lighter Required
Begin preparation by sliding a 2.5” long piece of shrink tube 1” onto the
cable end
Heat the shrink tube with a lighter until it is constricted around the cable
and the portion beyond the cable is reduced to its minimum diameter. Rotate
the cable to assure that all sides of the tubing are shrunk.
ALLOW THE SHRINK TUBE TO COOL FOR A FEW SECONDS BFORE PROCEEDING
Once the shrink tube is cool enough to touch, fold it back and wrap with vinyl electrical tape until the tape extends ~1/2” beyond the base of the shrink tube. Failing to tape beyond the base of the shrink tube could result in it being pulled off during installation.
Method #3 – No Heat Gun or Lighter
- Begin preparation by sliding a 2.5” long piece of shrink tube 1” onto the cable end
- Affix the shrink tube to the cable using vinyl electrical tape
- Fold the shrink tube back and wrap with vinyl electrical tape until covered
- Once the leading end of the cable is protected, it can be installed per the best practices outlined in the BICSI Information Technology Systems Installation Methods Manual (Latest Edition). The cable can then be terminated with Leviton Cat 6A connectivity using the provided instructions.
WARRANTY
This product is subject to the terms & conditions outlined under the Leviton
