dwdm sfp 10g factory
A dwdm sfp 10g factory quotation is comparable only after the channel, rate, reach, and host are written as one line. This desk works as an independent sourcing partner: it does not manufacture modules, hold cages, or speak for a carrier.
Start with the optical path, not a unit figure. Name the ITU-T grid spacing you intend to use, the nominal wavelength, the fiber plant, and the switch or mux cage the module must seat in. A price without those fields mixes different parts.

Evidence rows before a factory number is useful
Each row is a question for the supplier. A family catalog does not prove that the offered SFP+ matches the row.
Ask for the ITU channel, the nominal wavelength in nanometers, and whether the grid is 100 GHz or 50 GHz. An example question is channel 34 near 1550.12 nm on the C-band grid. That example is a prompt, not a stocked part.
Separate 10 Gigabit Ethernet at about 10.3125 Gbit/s from STM-64/OC-192 at about 9.95 Gbit/s, and from OTU2 if the line rate differs. A module coded for one rate is not automatically the other.
An 80 km label is a link-budget class. At 0.22 dB/km, 80 km of fiber is about 17.6 dB before connectors, splices, and margin. Ask for transmit power and receiver sensitivity on the named module, then do the subtraction yourself.
Request whether digital optical monitoring reports Tx power, Rx power, temperature, and bias current, and which MSA bytes the host can read. A screenshot from another platform is not that report.
State the switch, muxponder, or chassis, including the software release. OEM EEPROM coding and a generic MSA identity are different offers. This desk has not plugged the module into your cage.
A public ITU optical-fibre recommendation page checked on 2026-10-27 can suggest which questions to ask. It does not certify any module this desk forwards.
Where a 10G DWDM module sits in the purchase
-
Colored wavelength on the line side
The module emits one narrow C-band wavelength into a mux. Record the mux channel plan so two factories do not quote adjacent channels that your filter cannot pass. Insertion loss of the mux is a separate line from the module optical budget.
-
Host cage and electrical side
SFP+ is the usual mechanical cage for this rate. Confirm the host supports the electrical interface, the power draw in watts, and the operating temperature you need: a commercial window around 0 to 70 °C is not an industrial window around −40 to 85 °C.
-
Fiber plant under the wavelength
Single-mode G.652 fiber is the usual plant for an 80 km class question. Multimode fiber at 850 nm answers a short data-hall link, often a few hundred meters, and does not belong in the same price cell. Chromatic dispersion on the order of 17 ps/nm/km times 80 km is about 1360 ps/nm. Ask for the module dispersion tolerance in ps/nm and whether a compensating module is excluded.
Continue in the inquiry cards, the 80 km field list, or the procurement note.
Questions that change the quotation
Which connector leaves the cage?
LC duplex is the common SFP+ optical port. A bid that substitutes SC, or that ships a pigtail instead of a cage module, is a different line. Ask for the connector polish if the plant specification names it, plus return loss if a jumper is included, and channel width of 100 GHz or 50 GHz so the mux slot is unambiguous. A connector mating cycle limit belongs on test cords, not on the module shell.
What sits outside the module price?
Mux channels, dispersion compensation, LC jumpers, coding fees, firmware, freight, duties, and the US destination. Those items move the landed total even when the wavelength matches.
New cage or a pulled module?
A refurbished unit can be a valid offer for a legacy host when the seller states condition, DOM hours if available, warranty months, and whether the EEPROM was rewritten. Do not average that unit figure with a new-build quote.
Which document is only a question source?
FCC equipment-authorization rules may apply to some intentional radiators and not to a passive optical plant. Ask the supplier which authorization, if any, attaches to the exact model. This page does not decide that.

Write the wavelength, rate, reach class, connector, host, quantity, destination, and timing. The desk coordinates replies. It does not publish a standing unit price and it does not claim the plants were audited here.
