Thorlabs FC1064-90B-APC (lot of 16)

Description

The Thorlabs FC1064-90B-APC is a high-performance 2×2 single-mode fiber coupler designed to operate at a wavelength of 1064nm with a 90/10 coupling ratio. This model is ideal for applications that require precise optical signal splitting, with a significant portion (90%) directed to one output and a smaller portion (10%) to the other. It is equipped with APC (Angled Physical Contact) connectors, which help reduce back reflections, improving performance in sensitive optical systems.

Key features include:

• Wavelength: 1064nm
• Coupling Ratio: 90/10
• Connector Type: APC (Angled Physical Contact) for reduced back reflection
• Low Insertion Loss: 9.5-10.5 dB (depending on the specific configuration)
• Excess Loss: 0.2dB
• Directivity: >55dB, ensuring high signal separation.

This coupler is well-suited for applications such as fiber-optic communications, research laboratories, and systems requiring precise power splitting without significant signal degradation. Its rugged design supports a broad operating temperature range, from -40°C to +85°C, making it suitable for both standard and harsh environments
