Ekivalan OM4 Duplex LWL Patchkabel LC/ST 50/125 µm Heather Violet 7 m COZOM4LCST2SE0070A

With a modal bandwidth of 4700 MHz·km at 850 nm, this OM4 multimode fiber patch cable delivers exceptional performance for high-speed data transmission over short to medium distances. The 7-meter length provides flexibility in network layout while maintaining signal integrity.

Overview

The Ekivalan COZOM4LCST2SE0070A is a duplex fiber optic patch cable featuring OM4 multimode fiber with a 50/125 µm core/cladding diameter. It is terminated with an LC connector on one end and an ST connector on the other, both with UPC polish for low insertion loss and high return loss. The cable jacket is made of LSZH (Low Smoke Zero Halogen) material in a distinctive heather violet color, ensuring safety in case of fire and easy identification.

What stands out

• OM4 fiber supports 40/100 Gigabit Ethernet up to 150 meters at 850 nm.
• Duplex construction with two fibers enables bidirectional communication.
• LC connector's small form factor saves space in high-density environments.
• ST connector's bayonet-style locking provides secure connections.
• LSZH jacket reduces toxic smoke and corrosive gases in fire situations.
• UPC polish minimizes back reflections for stable signal transmission.
