DEVICE RFQ · SAME FIELDS FOR EVERY FACTORY
A fiber onu device quotation is comparable when every respondent answers the same row set. LinkScope Sourcing 09 sends that row set outward. It does not pick a winner and it does not hold inventory.
Bind each claim to the model in the reply. A catalog page for a product family is context, not the evidence row.
Ask for the current sheet that shows interface type, data rate, wavelength, fiber mode, reach, and temperature range. Note the document date.
Transmit power, receiver sensitivity, and optical budget should appear with units. If the supplier cites an optical class, ask which loss figure in dB that class maps to for this hardware.
Name the OLT platform and the software release you run. Host compatibility is a statement about that pair. A matching SC connector does not establish it.
If the destination needs an authorization file, ask the supplier to attach the file for the exact model. An FCC equipment-authorization overview checked on 2026-10-27 explains that applicability is model-specific. This desk does not certify products.
Currency, per-unit or whole-order basis, Incoterm, freight, duties, and lead-time anchor. Keep firmware, voice features, and spare power adapters on their own lines.
The inquiry cards are labels you can paste into the brief. They are not a warehouse list.
Keep one worked row beside the ledger so a reply can be checked. Background: the buyer already runs an OLT and needs a fiber onu device on a single-mode drop. Process: ask for GPON or EPON, the line rate (a public GPON discussion often cites 2.488 Gbit/s downstream and 1.244 Gbit/s upstream), wavelength at 1310 nm up and 1490 nm down, any 1550 nm overlay, transmit power, receiver sensitivity, optical budget, return loss, insertion loss, connector polish, and connector mating-cycle guidance. Result you can compare: either the named model fills those cells with units, or the factory marks a deviation. A Class B+ figure near 28 dB is one such cell, not a limit this desk has tested. Power over Ethernet is a separate cell from a voice port. A multimode jumper does not satisfy a single-mode plant, and a managed profile is optional only when the buyer writes that diagnostics are unnecessary.
Some devices hand Ethernet frames through. Others route, translate voice, or expect a management profile. Ask which behavior the model uses and which profile your OLT requires. That split is the access-network version of a managed-versus-simple choice: more visibility can mean more configuration to keep through the lifecycle.
Access drops are usually specified as single-mode. A multimode jumper from a data-hall habit will not become a valid substitute because the connector shell looks familiar. State the fiber mode in the brief and ask the supplier to confirm the device is built for that plant.
Ask for APC or UPC, the return-loss figure the sheet publishes, and a connector mating-cycle note if the pigtail will be reseated during test. Insertion loss of a dirty or mismatched adapter is an installation issue, not a reason to average two quotations.
A POTS port is not a PoE port. If the site needs Power over Ethernet at the UNI, say the standard and the budget in watts. Do not infer it from a four-port faceplate.
There is no file-upload control on this form. Paste the model, the port map, the optical questions, the quantity, the US destination, and the timing into the requirement field. If a drawing must follow, say so and send it after the opening reply.
Deviations should come back as deviations. A substituted optical class or a missing voice port is a different line, not a tidier price.
