Tecowin OM4 LC-LC dvigubas šviesolaidinis komutacinis kabelis, 50/125 µm, 3 m

4700 MHz·km @ 850 nm – this Tecowin OM4 duplex fiber patch cable is built for speed. In your home lab or small office, it ensures reliable 10G, 40G, or even 100G Ethernet connections over short distances. With LC connectors on both ends and a 3-meter length, it's perfect for patching between switches, servers, or storage devices.

Why you'll appreciate it

• Multimode OM4 fiber (50/125 µm) delivers higher bandwidth than OM3, so your network won't bottleneck.
• LSZH jacket (Low Smoke Zero Halogen) in aqua color – safer for indoor use and easy to identify as OM4.
• Low insertion loss (≤ 0.3 dB) and high return loss (≥ 30 dB) mean clean, strong signals.
• Duplex design with crossed polarity (A-B) ensures proper transmit/receive alignment.
• Minimum bend radius of 7.5 mm – flexible enough for tight spaces.

Who is it for?

If you're setting up a home network with 10G equipment, or managing a small business server room, this cable is a smart choice. It's also great for anyone upgrading to faster Ethernet and needing reliable short-range fiber links.

How to use

Simply plug the LC connectors into your LC-equipped switches, servers, or media converters. The crossed polarity means one fiber transmits and the other receives, so you get a proper link without extra configuration. Just make sure the equipment supports OM4 multimode fiber.

Tips: When routing the cable, avoid sharp bends – keep the bend radius above 7.5 mm to prevent signal loss. Use the aqua color to quickly identify OM4 cables in your patch panel. For best performance, clean the connectors before plugging them in.
