Testing two fibers at a time:
- Saves time by testing both fibers in opposite directions simultaneously.
- Allows link length measurement with every test.
Fiber OWL 7 BIDI certifiers have two dual-fiber test modes:
- PAIR: both fibers in a pair are certified in only one direction. Cabling standards only require fibers to be tested in one direction, so PAIR mode is the fastest way to certify fiber pairs according to cabling standards.
- BIDI: both fibers in a pair are certified at two wavelengths in both directions. Bi-directional testing is not required by standards, but many end-users will request BIDI testing anyway. BIDI test mode is the more thorough, but is also more complicated and time-consuming.
NOTE: Fiber OWL 7 series testers come configured with the new TIA-568-3.D cabling standard. This new standard introduces some changes in terminology that experienced fiber professionals should know in order to get up to speed with the new standard.
Testing one fiber at a time: Fiber OWL 7 series testers can also be used as a traditional one-fiber certifier (when used with a separate stand-alone light source) or as a stand-alone optical power meter.

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!
