Independent sourcing partner for Fiber Optic Equipment · factory quotations compared on the same ONT interface, wavelength, quantity, and destination

QUESTION-LED PLANNER

fiber ont device

Use this page to close the open cells on a fiber ont device before a factory sees the brief. While the worksheet is filled, LinkScope Sourcing 08 serves as an independent sourcing partner. The planner is a sequence of buyer questions. It is not a sustainability pledge, a carbon account, or a claim that a plant was audited.

PON rate still open? Polish still open? Host release still open?

Checked on 2026-10-27, ITU-T G.984.2 remains the GPON question source: 2.488 Gbit/s downstream, 1.244 Gbit/s upstream, nominal 1490 nm and 1310 nm. ITU-T G.9807.1 remains the XGS-PON question source near 9.953 Gbit/s, 1577 nm downstream and 1270 nm upstream. Pick one column before you ask for a price.

Quote scope written as a worksheet

  1. Rate and wavelength. Mark GPON or XGS-PON. Add whether a 1550 nm overlay is present. Leave the cell blank rather than guessing transmit power.
  2. Loss window. Write the designed drop loss in dB. Ask the supplier whether the datasheet cites a Class B+ style window of 13 dB to 28 dB, and to show receiver sensitivity at the wavelength you named.
  3. Fiber and connector. OS2 single-mode versus OM3 or OM4 multimode is a plant decision. SC/APC uses an 8 degree end face. Return loss and insertion loss limits travel with that polish.
  4. Power and ports. 12 V DC adapter in or out, Ethernet count, voice port, Wi-Fi in or out, and the temperature band: often 0 °C to 40 °C indoors, a separate question if the box is outdoors toward -40 °C to 65 °C.
  5. Commercial line. Pieces, destination, timing, currency, and per-unit or whole-order budget if you have one. High-end, mid-range, budget, or undecided is a preference, not a factory score.

Choices that should stay open until evidence arrives

Single-mode versus multimode

Single-mode OS2 is the usual match for a GPON or XGS-PON drop because the wavelengths and the reach were specified that way. Multimode can be the right plant for a short 850 nm Ethernet optic inside a hall. Accepting a multimode jumper as a substitute for an ONT pigtail fails the wavelength, even when the latch looks similar.

OEM-coded versus compatible

An OEM-coded fiber ont device may follow the OLT vendor policy with fewer provisioning surprises. A compatible device may be the reply you want when the host release is listed and OMCI behavior is described. Verify the tested software build before you accept the alternative. A shared model photo is not that test.

New versus refurbished

New condition should include unused optical ports and a stated firmware branch. Refurbished condition can be acceptable when mating cycles, cosmetic grade, and the warranty party are written down. Do not treat a lower accessory count as a small variation. It is a different delivered scope.

What this planner cannot close

No power-meter reading is produced here. No FCC grant is held by the desk; 47 CFR Part 2, reviewed on 2026-10-27, is the reminder to request model-level evidence. Dispersion at 10 Gbit/s, ingress protection, and dying-gasp behavior stay with the datasheet of the exact code you accept.

When the worksheet has fewer blanks, compare labels on the inquiry cards and send the packet with the brief form.
