INQUIRY CARDS · NOT A STOCK LIST
fiber adapter sc st
These cards help a buyer start a brief for fiber adapter sc st hybrids and for same-family SC or ST sleeves. A card is an inquiry label. It does not mean a panel is on a shelf, and it does not name a channel that has been audited.

How to read an SC to ST reply
A fiber adapter sc st body mates a 2.5 mm SC ferrule to a 2.5 mm ST ferrule. The shared ferrule diameter does not make the flange, the bayonet, or the polish interchangeable. Ask the supplier which side is the SC square body and which side is the ST bayonet, and whether both ends are UPC or both ends are APC.
Request the sleeve material on that hybrid. Zirconia ceramic and phosphor bronze show up on different datasheets with different mating-cycle counts. A count of 500 cycles and a count of 1000 cycles are both only useful when the test method is named. This desk does not run that test.
Insertion loss should be a maximum in dB at the wavelength you use. For single-mode links, buyers commonly ask the plant to quote the figure at 1310 nm and at 1550 nm. For multimode, the usual request is 850 nm and 1300 nm. Copy the supplier row. Do not average the two wavelengths into one marketing sentence.
Return loss follows the polish. UPC offerings are often specified in a 50 dB class and APC offerings in a 60 dB class. Those classes are checkpoints, not results measured here. If the drawing does not state the polish, stop the comparison.
Panel mounting is a second line. A hybrid bulkhead can be a D-hole, a square flange, or a snap fit. Give the cutout in millimeters and say whether dust caps are included. Then use the SC quotation fields to align commercial terms, and send the brief when the sleeve and the destination are both written down.
