How to read a wholesale reply

A wholesale reply can mean a carton of identical wavelengths, a mixed SX and LX plan, or a single coded module. Write the quantity unit before you rank the number. Two hundred pieces of 1310 nm is not the same purchase as two hundred pieces split between 850 nm and 1550 nm, because the fiber plant and the EEPROM coding differ.

Ask each respondent for the manufacturer and model they will actually ship, the nominal wavelength in nanometers, the data rate, the connector, the commercial or industrial temperature window, and whether digital optical monitoring is implemented. If the offer is an 80 km class part, move it to the factory field list and ask for minimum transmit power, receiver sensitivity, and dispersion tolerance in ps/nm. Copy those from the datasheet the supplier attaches.

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 be stated. If a reply says multimode for a single-mode campus span, move it out of the 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 is a different line. The RFQ form is where the brief is sent. When no photograph is attached to a row, 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.
