Product Overview
The Indoor Plenum Singlemode Interlocking Armor Assemblies offer the perfect balance of durability, safety, and high-speed performance for indoor networking. With a plenum-rated jacket, these assemblies meet NFPA fire safety standards, making them safe for installation in air spaces. The interlocking aluminum armor provides unmatched protection against physical damage without the need for additional conduit or innerduct, significantly simplifying installation and reducing costs. Pre-terminated connectors ensure a plug-and-play setup, saving valuable time and minimizing errors during deployments. With support for singlemode fiber, these assemblies excel in long-distance data transmission and high-capacity applications, such as backbone connections, data centers, and critical institutional networks. Their versatility and scalability make them an indispensable solution for networks of all sizes, from simple point-to-point links to large-scale redundant infrastructures.

Typical Indoor Plenum Rated Interlocking Armored Jacket Applications:
Our Indoor Plenum Rated Interlocking Armored Custom Pre-Terminated Fiber Optic Cable Assemblies help save time and money in indoor applications where innerduct or conduit is necessary, or in industrialenvironments which require extra protection. Although this option is priced higher than standard indoor distribution cable, it outweighs its overall price when compared the cost of purchasing innerduct/conduit, indoor fiber, and installation for both.
Interlocking armored cables are standard distribution cables inside a spirally wrapped aluminum interlocking armor with a heavy-duty outer jacket. This combination provides superior crush resistance. This type of cable is also useful for warehouses or attic areas where the presence of rodent chew hazards may exist.
Our pre-terminated fiber optic assemblies are perfect for headend termination to a fiber backbone, termination of fiber rack systems, multi-floordeployment where select fibers are used at each floor, or intra-building backbones. Our indoor plenum rated jacket assemblies arerated for all indoor installations, including plenum rated spaces. A cable rated for plenum installation will have low-smoke characteristics as defined by the NFPA (National Fire Protection Agency).
Standard QuickTreX® Manufacturing Features:
- Fast Custom ISO 9001 Certified Manufacturing in the USA. 2-millimeter color coded or sequentially labeled furcation tubing is installed on each strand for easy identification and extra durability before, during, and after the pull.
- Heat shrink tubing and glue set is used at the transition from the jacket to the furcation tubing providing superior strength and strain relief while pulling the assembly.
- Connectors inside the basket are staggered for less bulk and more flexibility.
- Each connector is individually plastic wrapped to prevent contamination by pulling lubricants and/or other contaminants.
- Each assembly includes a wrap around-label on both ends of the assembly which will include the QuickTreX® part number and individual serial number.
- Each Assembly includes a full test report. During our testing process all fiber ends are visually inspected with a fiberscope of 400 power or better for surface defects including, cracking, pitting, and scratches, on the glass surface of the connector. All connector ends are then tested utilizing a professional grade Loss Test Set.
- The test report is saved in our database for 1 year and can be requested at any time.
- Pulling Eyes (pulling baskets) if equipped are made from super strong polyethylene mesh and feature a free-spinning buckle to eliminate twisting of the cable during the pull. Heat shrink tubing is used at:
1. Where the basket meets with the turnbuckle (pull eye hook)
2. Where the basket ends and connects with the cable jacket to prevent snags and promote a smooth pull.
All assemblies 100ft and over will be placed on a spool for easy installation. Assemblies under 100ft will be neatly air spooled.
Strand Count Breakdown & Rationale
Selecting the appropriate strand count is critical for ensuring the network can handle current demands while allowing room for growth.
- 1 Strand: Ideal for simple point-to-point connections, such as linking two devices or secure dedicated systems, where only minimal capacity is required.
- 2 to 6 Strands: Suitable for small- to medium-sized networks, enabling both operational needs and limited scalability for growing businesses or facilities.

Questions & Answers
What is a pre-terminated fiber optic assembly?
A pre-terminated fiber optic assembly is a complete optical cable solution that comes with connectors already attached to the fiber strands.
These assemblies include components such as fiber cables, connectors, protective jackets, and pulling eyes, all designed to provide a seamless installation experience.
What length options are there for pre-terminated assemblies?
Pre-terminated fiber optic assemblies can be custom ordered to your desired length (10 feet or up to 5,000 feet.) according to your specific requirements. The assemblies are made to order based on the length you need.
All assemblies 100ft and over will be placed on a spool for easy installation. Assemblies under 100ft will be neatly air spooled.
What is a pulling eye?
A pulling eye is an additional attachment on pre-terminated fiber optic assemblies designed to facilitate installation.
It provides a sturdy attachment point for your pull string or rope, allowing you to pull the cable through conduits or tight spaces without damaging the connectors or fiber strands.
The benefit of using a pulling eye is that it reduces the risk of damage during installation, especially in complex pathways or confined spaces.
What connectors can it get on fiber optic assembly?
Common connector types available for pre-terminated fiber optic assemblies include LC, SC, ST, FC, and MTP/MPO connectors.
Connectors are staggered to reduce the pulling basket diameter and promote an easy and more flexible cable pull. Plastic wrap is also applied to prevent contamination during installation
What is a LC connector?
An LC (Lucent Connector) connector is one of the most common types of cable connectors used in fiber optic networks.
It utilizes a 1.25mm ferrule (half that of FC, SC, and ST) and push-pull latch mechanism for secure and easy connections

Excellent Customer Service and Resolution
Tom personally reached out to me, took ownership of the situation, and worked to get my order resolved. He communicated with me directly, ensured the order was shipped, refunded the shipping charges, and provided a discount for the inconvenience.
What stands out most is the level of customer service and accountability shown throughout the process. It is refreshing to see a company stand behind its customers and make things right when an issue occurs.
I received my cable, the issue has been resolved, and I appreciate the effort Tom and his team put into correcting the situation. Based on how this was handled, I would not hesitate to do business with LANshack again.
Thank you, Tom, for your professionalism and commitment to customer service.

LANshack: Best custom CAT8 ethernet cable on the market!
I needed a custom 55 foot S/FTP (Shielded Foiled Twisted Pair) CAT8 indoor ethernet cable for ethernet backhaul between two Eero mesh routers. I did tons of research (including Grok) and I came across LANshack.com. They have the thickest 23AWG wire in their custom CAT8 cable vs 26AWG on Amazon (lower number is thicker; 23AWG wire has roughly twice the cross-sectional area of 26AWG). Excellent price per foot, and this cable is thick! Very quick turnaround once you order from them. I am very pleased with LANshack and I will order from them again for future projects!
