Fibre coupler adaptors let you combine cables together to extend your fibre network and strengthen its signal. We sell multi-mode and single-mode couplers. Multi-mode couplers are used for large data transfers at shorter distances. Single-mode couplers are used for longer distances where less data is transferred. Single-mode couplers are typically chosen for networking equipment in different offices and are used to network equipment within the same data centre backbone. We sell SC singlemode, SC OM3 multimode, SC multimode, LC multimode, ST-Through and LC/LC coupler quads. Our couplers are easy to manage. They let you connect your fibre cables and mount the coupler to a server rack or on your walls. You can also mount it to a fibre patch panel. We sell a fibre keystone insert for LC and SC terminations. These keystones can be used with LC OM3 multimode couplers, LC singlemode couplers, SC simplex couplers and LC multimode duplex couplers.
