SQS manufactures high-quality Polarization-Maintaining (PM) Single Mode Fiber Optic Patch Cords with consistently high extinction ratios (ER). We offer a wide range of connector types, including FC, SC, LC, MTP, and E2000, as well as AR-coated variants.
All patch cords are produced and individually tested in-house to ensure low insertion loss and return loss values exceeding 50 dB (PC) and 60 dB (APC).
We specialize in custom solutions tailored to your specific needs. Our advanced PM fiber alignment and low-stress bonding technology guarantee minimal angular misalignment and superior PER performance across the 405–1620 nm wavelength range.
Advantages
- Custom configuration options
- Extinction ratio (ER) up to 35 dB @ 1550 nm
- Active alignment of PM fiber to the connector key
- Variant for transmitting signal power up to 5 W @ 1550 nm
- PM patchcords with MPO MTP connectors or fiber arrays
- Anti-reflective coating on the fiber end face on request
Applications
- Interferometry and fiber optic gyroscopes
- Quantum optics and communication
- Coherent laser systems
- Precision sensing and metrology
- PM fiber links in telecom and testing
