Features

SM Patch Cables for Signal Transmission from 305 nm to 2100 nm
FC/PC 2.0 mm Narrow Key Connectors on Both Ends
Low Back Reflections (High Return Loss): 50 dB (Typ.)
Each Cable is Individually Tested
Available from Stock
Two Dust Caps Included

Thorlabs offers single mode patch cables with FC/PC connectors on both ends. Each cable is manufactured in our facility on state-of-the-art equipment and individually tested to ensure low back reflection (return loss) at fiber-to-fiber junctions. Available from stock, these cables feature Ø3 mm PVC protective jackets with internal kevlar threads for durability in the lab.

Each patch cable includes two protective caps that shield the ferrule ends from dust and other contaminants. Additional CAPF Fiber Caps for FC/PC-terminated ends are also sold separately.

Mating sleeves are available to connect FC to FC and FC to SMA connectors. These mating sleeves minimize back reflections and ensure proper alignment of the cores of each connectorized fiber end. Thorlabs also offers AR-Coated Single Mode Patch Cables, which have an antireflective coating on one fiber end for higher performance in fiber-to-free space applications. If you cannot find the appropriate stock patch cable your application requires, Thorlabs offers custom patch cables, which typically ship the same day they are ordered (for orders placed weekdays before 2 PM EST). Please see the Custom Cables link to the right to order a custom fiber patch cable.
