The G-Link FSW Series Miniature Optical Switch is a key component for next-generation all-optical networks. Engineered for industry-leading performance, it combines low insertion loss with high stability in a compact mechanical package.
- Versatile Configurations: Available in 1×1, 1×2 (T/D), and 2×2 (B/BA/T/A) configurations to suit various routing needs.
- Superior Performance: Features excellent return loss (≥50dB for SM) and low crosstalk (≤ -55dB), ensuring minimal signal interference.
- Robust Operation: Designed to operate reliably in harsh temperatures ranging from -20°C to +70°C.
- Flexible Control: Supports Latching and Non-Latching control types with standard TTL/5V drive.
