Our Custom Indoor Plenum Rated OM5 (50/125) - 10/40/100/400 GIG- Multimode Pre-Terminated Fiber Optic Assemblies offer the latest state-of-the-art fiber optic technology. It's rated for up to 400GIG and since it includes the same 50/125 Micron core it's downward compatible with 10G, 40G, and 100G networks. At the rate at which the latest technologies are advancing you can be certain our OM5 assemblies are your best bet at future-proofing your network infrastructure. OM5 cable also supports wave division multiplexing with allows for different light wavelengths to be sent through the same strand. As components advance your OM5 infrastructure will allow you to benefit from this technology and expand your network using your existing strands that are in place.
Typical Indoor/Outdoor Jacket Applications:
Our Indoor/Outdoor Pre-Terminated Fiber Optic Cable Assemblies are perfect for connecting the networks of two buildings through the use of an underground conduit, headend termination to a fiber backbone, termination of fiber rack systems, multi-floor deployment where select fibers are used at each floor, or intra-building backbones. This cable is suitable for indoor and outdoor use, so there is no 50 foot fire code requirement traditionally found with outdoor (OSP) cable. This indoor/outdoor utilizes a DryGel water blocking system in the cable core and has a UV and fungus resistant outer jacket making it a very versatile and perfect choice for a large variety of installations. This cable can be installed and left exposed in outdoor locations where blunt force or rodent chew damage is not a concern.
Our indoor/outdoor assemblies include a plenum rated jacket which is perfect for installations that transition from an outdoor location such as an underground conduit, to an interior location that requires a plenum rated jacket such as ventilation shafts. 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:
- Where the basket meets with the turnbuckle (pull eye hook).
- 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
Choosing the correct strand count depends on your network's specific needs and scalability. 2-strand configurations are perfect for simple point-to-point links, while 4 to 6 strands provide extra capacity and moderate scalability for departmental setups or smaller facilities. For more complex layouts or businesses planning long-term growth, 8 to 12 strands allow high-speed data transmission with redundancy for voice, video, and data pathways. These assemblies are designed to serve a wide range of needs while providing flexibility to expand or update your network.
Typical Applications by Industry
- Healthcare: Ensures secure data transfer for telehealth, imaging, and patient records.
- Educational Institutions: Connects labs, classrooms, and campus facilities with high-speed networks.
- Retail and Warehousing: Supports POS systems and inventory management across multiple locations.
- Telecommunications: Provides stable data transfer for metro and backbone networks.
- Enterprise: Handles large-scale departmental networks with segmentable pathways for data, voice, and video.

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!
