How to read a wholesale reply

A wholesale figure can mean a carton of identical channels, a mixed channel plan, or a single coded module. Write the quantity unit before you rank the number. Ten pieces of one ITU channel is not the same purchase as one piece each of ten channels, because the mux plan and the EEPROM coding differ.

Ask each respondent for the manufacturer and model they will actually ship, the nominal wavelength in nanometers, the grid spacing, the data rate, the connector, the commercial or industrial temperature window, and whether DOM is implemented. If the offer is an 80 km class part, also ask for minimum transmit power, receiver sensitivity, and dispersion tolerance in ps/nm. Copy those from the datasheet the supplier attaches. Do not let a brochure range stand in for the model.

Host compatibility is a separate column. Record the platform name and software release. A module that links on one vendor cage can be rejected by another cage when the vendor-id bytes do not match that platform policy. This catalog does not run that test. Fiber mode should say single-mode. If a reply says multimode, move it out of the DWDM 10G comparison.

Normalize currency after you know whether the figure is per module or for the whole order. Freight, duties, coding fees, and LC jumpers stay visible. A lower printed rate on a refurbished pull, or on a channel your mux cannot pass, is a different line. The 80 km field page lists the rows to align, and the RFQ form is where the brief is sent.

When no photograph is attached to a card, use the name as the inquiry label and put the missing optical values in the requirement field. An empty image is not a quality judgment.
