Techlogix Networx M4D-KS-LCLC Fiber optic keystone adapter -- duplex LC to LC -- OM3/OM4
Get out the cable stretcher!' This is a mildly humorous prank to play on a greenhorn cable installer, but sometimes, don't you wish you actually had one?
Fiber couplers (sometimes called adapters) are a simple and stable way of extending your fiber optic cable, or creating a service point at a patch panel.
These are also great for coupling your SSF™ bulk fiber installation cable to a patch cable which will increase the longevity of the install cable.
