Product Overview
Our QuickTreX® Custom Pre-Terminated Fiber Optic Assemblies have a longstanding reputation for quality and reliability. When we receive your custom order, we build the assembly to your specifications using the finest materials to our exacting standards. The assembly is made in the USA by skilled technicians under controlled conditions and comes to you fully tested and ready for immediate installation.
Our indoor plenum rated jacket assemblies are rated 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).
Typical Applications Include:
- Headend Termination to a fiber "backbone"
- Termination of fiber rack systems
- Multi-floor deployment where select fibers are used at each floor
- Intra-building "backbones"
Standard QuickTreX® Micro-Distribution Features:
- All Pre-Terminated Micro-Distribution Assemblies will be custom made at the time of your order, built with Corning® fiber and premium components to your specifications.
- All micro-distribution assemblies will be constructed using 12 strand grouped breakouts. Each strand will be reinforced with 2mm furcation tubing which helps ruggedize each strand and help protect it during installation. Each strand will include a sequential numerical label. Each 12 strand breakout kit will also be sequentially labeled to help identify each strand on opposite ends of your assembly.
- The buffer tubes will be securely fastened to each 12 strand breakout kit using high strength adhesive type heat shrink tubing.
- The first main breakout will be 12 inches from the main jacket and each group of 12 strands will include a 36" breakout. The main 12 inch breakouts kits will include a 6" stagger.
- The connectors itself will also be staggered to minimize the size of the pulling basket which will be approximately 1".
- Heat shrink tubing will be used at:
-
- The transition from the buffer tubes to the cable jacket.
- The transition of each 12 strand inner cable to the breakout kit
- Where the basket meets with the turn buckle (pull eye hook)
- Where the basket ends and connects with the cables jacket
- One wrap around label will be attached to each end of the cable assembly for identification. The label text includes the cable part number and a unique serialized number.
- 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.
Micro-Distribution Features:
- Perfect for High Density Infrastructures
- Saves Space in Data Racks, Cabinets, and Closets
- Constructed of the highest quality materials
- Made to exacting industry standards
- Tested to meet or exceed EIA/TIA 568/ GR-409-CORE
- All aramid tensile strength members within sub-units
- Smaller cable diameter & more flexibility
Typical Applications by Industry
- Large data centers rely on this assembly for wide-scale redundancy and ultra-fast operations.
- Telecommunications use it for backbone traffic flow at higher capacities.
- Healthcare facilities integrate this configuration to connect multi-site networks seamlessly.
- Educational institutions employ it for extensive, campus-wide networking.
- Government environments depend on its high security and reliability for critical operations.
Strand Count Breakdown & Rationale
With 72 strands, this assembly supports complex networks with advanced scalability and reliability. Its subunitized structure allows for easy handling while providing sufficient capacity for high-bandwidth demands and redundancy. This makes it a preferred option for large-scale enterprises planning future expansions

I bought 200ft SMF 6 strand. The quality is amazing. I’m not sure what I was expecting but I am blown away. I highly recommend this to anyone looking for smf.
Vytas
First time I've ordered from LANshack, will definitely use them in the future for pre-terminated custom fiber assemblies. Shipped quick and direct to customer.

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

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!

This is the second time ordering from LANshack. Both times were great experiences. If you are a DIY person who has tried to but RJ-45 connectors on cat cable you can imagine how great it is to just do the measurements and avoid that brain damage. Great service and good quality product.
