High Performance Low Loss Patch Cords
For high speed data rates
Singlemode (9/125) G.657.A1 Duplex Fibre Patch Cords are designed for high-speed data networks using Ethernet and fibre channel applications in data centres, telecommunications, LANs, WANs, and enterprise network applications.
The fibre cores of the patch cables are G.657.A1 singlemode (9/125) for optimal performance. The low loss LC or SC duplex connectors, terminated with high-performance singlemode ferrules using UPC/APC polish, guarantee reliable data transmission. The patch cord comes with standard boots for easy installation.
Choose the cable diameter that suits your needs—options include 1.6mm, 1.8mm, and 2.8mm. Patch cables are manufactured using an LSZH jacket as standard but are available with Euroclass rating up to B2ca for enhanced fire safety performance – contact our team for details.
Singlemode (9/125) G.657.A1 duplex fibre patch cords with LC or SC duplex low loss connectors have a 25-year warranty and comply with all applicable IEC, EIA TIA, and Telcordia standards.
