Cable Matters 5-Pack LC UPC Duplex Fiber Optic Keystone Coupler Jack, OM1/OM2/OM3/OM4 Multimode, OS2...

Our Experience

Upgraded from my old one and I gotta say, these Cable Matters LC UPC Duplex fiber optic keystone couplers are a solid upgrade. The polished metal finish gives them a sleek look that blends right in with my setup. No more dealing with those cheap plastic ones that always felt like they were gonna break.

I've tried others before, but these offered the best balance between price and performance. They've been working smoothly with my OM1 through OM4 cables for weeks now, no issues whatsoever.

My only minor gripe is that the keying mechanism could be a tad tighter. It's not a deal breaker by any means, but I sometimes wish it'd snap in more securely. But hey, for $15, you can't beat these babies!
