SC QUOTE PATH
optical fiber adapter sc
An optical fiber adapter sc request is a path of four stations, not a single price cell. Each station has to be filled before two factory replies can sit on the same row. LinkScope Sourcing 12 coordinates that path. It does not mill the sleeve and it does not certify the link.
- 1. BodySimplex, duplex, or the flange style the plate already uses.
- 2. SleeveMaterial and the ferrule it is cut for.
- 3. PolishUPC or APC on both mating faces.
- 4. PaperLoss rows, exclusions, and the destination lane.
Lifecycle of one SC quotation
Use this matrix when you ask plants about an optical fiber adapter sc. The columns are the life of the buy, not a claim that any plant has already passed them.
| Stage | Buyer writes | Factory returns | Stop if missing |
|---|---|---|---|
| Specify | SC to SC, or SC on one side only if the other side is a different family | Exact model and a drawing number | Only a family name |
| Sleeve | Single-mode or multimode, and whether zirconia is mandatory | Sleeve material and mating-cycle count with the method | Color photo used as the material |
| Loss | Wavelengths you will accept in the comparison | Maximum insertion loss in dB and return loss in dB | A typical value with no wavelength |
| Commercial | Quantity of adapters or loaded panels, currency, per piece or whole order | Incoterm or equivalent, freight, and what is excluded | A unit rate with caps and freight omitted |
| Evidence | Which documents you will read before release | Current datasheet bound to that model | A brochure for a different footprint |
Single-mode SC sleeves are commonly zirconia because the alignment tolerance is tighter over longer reaches. Multimode SC sleeves are often phosphor bronze and may be enough for short building runs when the transceiver and the fiber agree. That split is a design choice for your link, not a ranking this desk publishes. If the installed plant is already single-mode, do not accept a multimode sleeve to close a price gap.
APC end faces are angled. UPC end faces are domed. Crews often recognize green housings as APC and blue housings as single-mode UPC, but housing color is an identifier to confirm, not a test report. Require the polish word on the drawing. A mixed pair is a damage risk, not a compatible alternative.
Data rate does not live inside the adapter. A 1 Gbit/s optic and a 10 Gbit/s optic can share an SC sleeve if the ferrules and the fiber mode match. The rate still belongs on the optic line so nobody prices a sleeve as if it included the module. Reach and optical budget stay with that optic line too. SC and ST sleeves are cut around a 2.5 mm ferrule. An LC body is 1.25 mm and cannot fill an SC request. Ask for maximum insertion loss and return loss in dB at 1310 nm and 1550 nm for single-mode, or at 850 nm and 1300 nm for multimode, plus a connector mating cycle count. A 500-cycle rating and a 1000-cycle rating are different drawings. Buyers often ask whether return loss sits in a 50 dB UPC class or a 60 dB APC class. Those rows come from the plant datasheet. This desk does not measure them.
Delivery questions that change the SC number
Are dust caps and the flange screws inside the rate?
Say whether each adapter ships with caps and whether a loaded panel includes the mounting hardware. A bare sleeve in a bag and a flanged body in a tray are different pack counts.
What temperature range is printed for the body you will receive?
Ask the plant to copy its operating range. Some indoor plates are specified only for a controlled room. An unheated hut needs the range the drawing actually states, for example a wide outdoor span or a narrower office span. Leave the cell blank if the datasheet is silent.
Which charges sit outside the adapter price?
Freight to the US destination, duties, inspection, and any kitting of pigtails. A target budget can use the same slice: currency, and per adapter, per panel, or the whole order. Supplier preference, if you add one, is your buying stance.
Diagnostics such as a link light or a power meter reading are not produced by the sleeve. If the project needs a test report on a mated jumper, name the jumper as its own line. The adapter quotation should not absorb that labor. The inquiry cards are labels for the body. The brief form is where the path is sent.
Compare two SC replies only after the columns match
Keep
- Model, sleeve material, polish, and flange
- Maximum insertion loss with wavelength
- Return loss with the same polish word
- Quantity unit and currency
- Destination and the timing basis
Park as a deviation
- A different ferrule size, such as LC 1.25 mm offered against an SC 2.5 mm request
- A quad body offered against a simplex cutout without a new drawing
- Refurbished bodies when you wrote new, unless condition and mating history are documented
- A loss figure copied from another model in the same catalog
OEM-marked plates and unmarked compatible plates can both be quoted. The compatible offer needs the same sleeve evidence and a statement of what the host vendor will or will not support. This desk does not decide that policy. It refuses to hide the difference inside one unit price.
