Product Overview
The Stock SC to SC 50/125 OM3, 10 GIG Multimode Duplex Patch Cables are designed to deliver high-quality performance and dependability in various networking environments. Each cable is crafted with two strands of multimode fiber featuring a 50/125µm core, enabling efficient data transfer at gigabit speeds. Equipped with SC connectors that feature ceramic ferrules and UPC polish, these cables ensure low insertion loss and better than -35dB back reflection for consistent signal integrity. The aqua-colored OFNR-rated jacket enhances both visibility and flame resistance, making these cables a dependable choice for long-term use.

- Data Centers: Perfect for connecting high-performance equipment like servers and storage devices.
- Healthcare: Suited for high-bandwidth tasks such as imaging systems and electronic medical records.
- Education: Reliable for campus-wide LAN installations and networking solutions.
- Media and Entertainment: Ensures flawless data delivery for video, audio, and live-streaming applications.
- Government and Military: Supports secure, high-efficiency communications in specialized environments.
- Telecommunications: Facilitates reliable data transfer in extensive network infrastructures.
Specifications in Depth
Each cable is built with OM3 multimode fiber and supports operating wavelengths of 850nm and 1300nm, allowing smooth gigabit-level performance. The ceramic ferrules and precision UPC polish minimize insertion loss (<0.2dB) and improve return loss (>35dB), ensuring clear and stable signals. The cables are flame-resistant thanks to their OFNR-rated jackets and can withstand operating temperatures from -40°C to +75°C.
Configured with pre-terminated SC connectors, these cables are designed for quick and easy deployment, particularly in data-intensive setups. Pulling eye options are available to simplify installations, especially in high-density or conduit environments. Versatile by design, these cables are offered in lengths ranging from 10 feet to 5000 feet to accommodate various project requirements.
Whether used for server-to-server connections or complex telecom setups, these cables deliver unparalleled reliability. See detailed table below for full specifications of this product.

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!

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.
