ZVK LVZAS33SM ST Singlemode Fiber Optic Coupler, Yellow

The ZVK LVZAS33SM is a premium ST simplex coupler designed for singlemode fiber optic connections. It provides reliable, low-loss coupling for OS1/OS2 (9/125 µm) fibers, making it ideal for telecommunication networks, data centers, LAN, and FTTx applications. The coupler features a durable metal housing with a zirconia ceramic sleeve, ensuring high precision and long-term stability.

Advantages

This ST coupler offers exceptional performance with typical insertion loss below 0.2 dB and return loss greater than 50 dB (UPC). Its robust construction supports over 500 mating cycles, and it operates reliably across a wide temperature range from -40°C to +85°C. The yellow color coding simplifies identification in high-density installations.
