Wavelength module
List 1310 nm, 1550 nm, 1625 nm, 850 nm, and 1300 nm as required, optional, or not needed. A supplier that offers a two-wavelength unit against a three-wavelength brief must label the missing line as a deviation.
Buyer checklist
Multi-wavelength OTDR meter supplier
Use this list before a multi-wavelength OTDR meter supplier reply is treated as complete. Each row is a question the buyer still owns. A supplier sentence that skips the pulse width, the connector, or the file format stays open.
Send the checked rows
Rows to close before an alternative is accepted
Dead zone conditions
Record event dead zone and attenuation dead zone in meters and the pulse width used, for example 5 ns or 100 ns. Without the pulse, the meter with the smaller printed number may be using a different setup.
Port, power, and files
Note the optical connector, the charger range, and whether traces export as SOR or a private format. Host compatibility is this file path, not a claim that the meter works on every platform.
Evidence packet
Ask for a datasheet revision and, when you need it, a calibration record tied to the serial number. FCC or NRTL paperwork is requested for the exact model when your import or site rule calls for it. This page does not decide that applicability.
Single-mode and multimode should not be mixed to fill a price cell. If the plant is multimode, an 850/1300 nm module is the relevant question. If the plant is single-mode feeder, 1310/1550 nm is the relevant question. Dispersion and optical budget from the link design tell you which distance range to request. They do not set the meter’s dynamic range.
Measurement accuracy on a brochure is incomplete until averaging time, index of refraction, and the fiber type used in the test are stated. A typical G.652 group index near 1.468 is a starting question for single-mode traces, not a value this desk assigns to your route. Confirm the index your engineers already use so traces from two meters can be overlaid.
An alternative supplier is acceptable to review when every open row above is answered. A lower unit figure with a missing launch reel, a missing wavelength, or an expired calibration date is a different scope. Keep that difference visible when you compare inquiry names.
Open points the form should still carry
- Quantity in pieces or kits, and whether each kit includes a launch fiber of a stated length.
- US destination and the week requested for receiving inspection.
- Currency and whether an optional budget is per instrument or for the whole order.
- High-end, mid-range, budget, or undecided preference, marked as a buyer preference.
- Any screen requirement, including a 7 inch color LCD, kept separate from the optical module.
Receiver sensitivity and transmit power describe transceivers more than an OTDR. If your brief also buys optics, put those lines in a different block so they are not priced as meter accessories. Return loss of the connector under test still needs a clean end face. The checklist does not replace that inspection.
Submit the checklist as the RFQ core
Copy the closed rows and the still-open rows into the requirement field. Factories can then answer the same multi-wavelength OTDR meter supplier questions.
