Ultra Low Loss 3 Port Optical Circulator High Isolation 1310nm/1550nm for DWDM and Fiber Networks

‌Ultra Low Loss 3 Port Optical Circulator - High Isolation 1310nm/1550nm for DWDM & Fiber Networks‌

Enhance your optical network performance with our ‌Ultra Low Loss 3 Port Optical Circulator‌, engineered for ‌high isolation and minimal signal degradation‌ in ‌1310nm and 1550nm‌ wavelength applications. Ideal for ‌DWDM systems, fiber optic networks, and telecom infrastructure‌, this circulator delivers ‌exceptional signal integrity‌ with ‌ultra-low insertion loss (<0.6dB)‌ and ‌high isolation (>50dB)‌, ensuring reliable data transmission in demanding environments.

‌Key Features:‌
* ‌Ultra-Low Insertion Loss‌ (<0.6dB) – Minimizes signal attenuation for clearer transmission
* High Isolation‌ (>50dB) – Reduces crosstalk and interference
* Dual Wavelength Support‌ – Optimized for ‌1310nm & 1550nm‌ bands
* Compact & Robust Design‌ – Easy integration into dense optical setups
* Wide Operating Temperature Range‌ (–40°C to +85°C) – Stable performance in harsh conditions

Applications:‌

* DWDM/CWDM Networks‌ – Efficient channel routing
* Fiber Optic Amplifiers (EDFA, Raman)‌ – Signal management
* Telecom & Data Centers‌ – High-speed optical communication
* LIDAR & Sensing Systems‌ – Precision light direction control

Designed for ‌long-haul and metro networks‌, our ‌3 Port Optical Circulator‌ ensures ‌plug-and-play compatibility‌ with industry-standard components. Its ‌high-power handling (300mW)‌ and ‌low polarization-dependent loss (PDL <0.1dB)‌ make it a ‌top choice for next-gen optical systems‌.

‌Upgrade your network with premium optical performance today!

HJY's Optical Circulator is a non-reciprocal passive device that directs light signals sequentially between ports (e.g., Port 1→2, Port 2→3, Port 3→1). It utilizes Faraday rotation and birefringent crystals to enable bidirectional optical routing with minimal loss. Key features include low insertion loss, high isolation, and compact design, making it ideal for telecommunications, fiber sensing, and dense wavelength-division multiplexing (DWDM) systems.
