Lightwin High Quality LC Duplex Multimode OM4 Fibre Coupler, Violet

The Lightwin High Quality LC Duplex Multimode Fibre Coupler is a precision-engineered adapter designed for reliable fibre optic connections in high-performance networks. Manufactured to exacting standards, this coupler ensures low insertion loss and high return loss, making it ideal for demanding applications in data centres, LANs, SANs, and FTTx environments.

Advantages

This LC duplex coupler features a zirconia ceramic sleeve for precise ferrule alignment and long-term durability. The violet plastic housing (PC/ABS) is flame-retardant (UL94 V-0) and RoHS/REACH compliant. With a typical insertion loss of ≤0.2 dB and return loss ≥20 dB, it guarantees excellent signal integrity. The flanged design allows easy panel mounting, and dust caps are included for protection when not in use.

Suitable for

• Data centres and server rooms
