A: Supports core diameters from 125 to 1580 micrometers; custom drilling available.

Q3: Can this connector operate at high temperatures?
A: Yes, high-temperature versions support continuous operation up to 250 degrees Celsius.

Q4: Do they include dust caps and sleeves?
A: Yes, each connector comes with a dust cap; SMA 906 includes optional alignment sleeves.

Q5: Are hex-nut and knurled coupling options available?
A: Yes, choose either knurled or hex-nut versions depending on installation needs.

Q6: What is the typical insertion loss?
A: Typically less than or equal to 1.0 dB; maximum less than or equal to 1.5 dB using comparable fibers.

Q7: Can I use these for panel mount?
A: Yes, they fit standard ST-style D hole cutouts with matching adapters.
