VOLT (VISUAL OPTICAL LENGTH TESTER) Almost all fiber optic experts own a VFL similar to VOLT but they don't get the extra benefit length testing features of VOLT!
VOLT functions as any good quality Visual Fault Locator (VFL). However, with the same price range as other VFL's, VOLT has the added benefit of doubling as a LOOPING length tester! Many cabling warranties and bids require meter-based length tests to prove the length of links.
VOLT uses 2 fibers and patch cables to establish a length test accurate to +/- 7 feet! VOLT's VFL functions up to 5 kilometers (3.1 miles). Loop length testing functions up to 1.5 kilometers.
As far as VFL function, VOLT holds its own against the best in the industry. As with any quality VFL, VOLT is a precision coupled laser diode! VOLT is not made as a cheap laser light pen. Rather, a multi-million dollar semiconductor machine is used in the manufacture of a special precision coupled micro-sized ball lens. This precision coupling allows VOLT to couple maximum red laser light into the tiny connector orifice of fiber optic links up to 5 kilometers (3.1 miles) of distance!
Features:
- Measures the length of both single-mode and multimode fiber with accuracy of ± 2.5 meters
- High-intensity visible red laser allows for visible fault location of breaks and micro bends
- Pulsed mode provides easy fiber identification
- Easy-to-read bright red 7-segment LED display
- 15 hours continuous use on one 9V battery
- Low battery indicator
- Handheld
- Lightweight

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.
