The unit is housed in an attractive handheld case made from high-impact plastic surrounded by a protective rubber boot, includes a high-resolution color LCD display, and an intuitive keypad for convenient data entry. The universal detector port includes two adapter caps: one for 2.5mm ferrule connectors, such as SC, ST, and FC; and one for 1.25mm ferrule connectors such as LC and MDC.
The unit will operate up to 50 hours on its high-capacity Lithium Polymer battery, and has built-in auto shutdown.
The Fiber OWL 7 (model #: F7) is a high-accuracy, high-resolution, microprocessor-controlled optical power meter. The detector port has a 75dB dynamic range making it ideal for a wide array of fiber optic testing applications, including standards-based fiber link certification (when used with separate light sources; sold separately).
When used with OWL fiber optic light sources (sold separately), the power meter includes a built-in loss wizard that helps you easily calculate the allowable loss for the fiber runs that you will be measuring. The meter stores physical fiber information for an unlimited number of jobs/projects, including link name, date, fiber type, fiber length, connectors, splices, temperature, and calculated or user-defined reference power values. In addition, the meter will store thousands of measured data points with customizable run name information.
The power meter port is equipped with an auto-wavelength recognition feature called AUTO MODE that automatically switches the wavelength being received from compatible OWL dual-wavelength, auto-testing light sources, such as OWL WaveSource Pro series light sources (sold separately). The detector senses the auto-switching signal from the WaveSource Pro light source, then automatically switches to that wavelength accordingly. This feature allows for simultaneous dual-wavelength optical referencing and power/loss testing, which increases productivity by decreasing testing time and human error.
The stored information can be selectively viewed, edited (measured again), printed, or deleted. Data may be downloaded via the built-in USB download port to our free OWLView software to produce professional certification reports.

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!
