Size: 30KM VFL + FC/LC Connector Number of Items: 1
I have used this on many occasions and it worked perfectly. I wish it had a larger storage to be able to store the adapter and a fiber patch cable with the unit. Even if it was an addition item to purchase with this.

Size: 30KM VFL + FC/LC Connector Number of Items: 1

Its ability to detect fiber optic faults such as breaks, poor connections, and bends is impressive, emitting a strong 650nm red light that makes identifying issues straightforward. I had read the reviews and some reviews reported issues with the LC adapter not fitting securely on the unit, luckily, I have not had this issue. ... show more
