Fiber optic coupler -- duplex multimode OM4 LC to LC coupler

'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 bulk fiber installation cable to a patch cable which will increase the longevity of the install cable.

Plus...these are pink!
