Questions & Answers
What is a fiber optic enclosure?
A fiber optic enclosure is a protective housing designed to organize, manage, and safeguard fiber optic connections, splices, and terminations. It acts as the central point where fiber optic cables are brought together, connected, and distributed while ensuring protection from environmental, mechanical, and handling damage.
What is a rack mount fiber optic enclosure?
Rack mount enclosures are designed to be installed in standard 19" or 23" racks in telecommunication rooms/closets or data centers.
What are the different types of chassis in fiber optic enclsoures?
The three main chassis are LGX, SHD, and UHD. LGX is the most common and standardized chassis type.
What does the 1, 2, 4, 6, or 12 "U" mean when talking about rack mount fiber optic enclosures?
The "U" stands for rack unit and it’s the standard measurement used to describe the vertical space equipment takes up in a 19 inch or 23 inch equipment rack. 1U equals 1.75 inches in height.
How many fiber strands can fit into a fiber optic enclosure?
The amount of fiber strands that you can fit into an enclosure will depend on how many panels or adapters you can fit and what type of connectors you choose. For example, if you choose a 1 panel enclosure and use a 12LC adapter panel, you can house or couple 12 fibers in that enclosure. If you use 12 MTP/MPO adapter panel, you can house or couple 144 or 288 strands depending on whether the MTP or MPO connector being connected is a 12 or 24 fiber connector.

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!
