2 pon port olt replies need the same cells
A 2 pon port olt request is comparable only when every plant prices the same two PON faces, the same uplink, the same power input and the same exclusion list. LinkScope Sourcing 07 writes that sheet and sends it to plants. The desk is not the manufacturer of the chassis and it does not keep a warehouse of two-port boxes.
Start with the network job, not the headline rate. Two PON ports can feed two 1:32 splitters or one 1:64 splitter plus a spare port. Those are different fiber plans. Record which one you are buying, the installed ONT generation, and whether the second port is live on day one or held as a spare. Quantity is in chassis. If you also need a spare power module, count that module on its own line.
Cells each supplier must fill for a two-port chassis
Leave a cell blank when the drawing is silent. A blank is safer than a guessed class, because a later alternative has to answer the same blank.
| Cell | What the plant writes | Buyer check |
|---|---|---|
| Identity | Manufacturer, model, hardware revision, new or refurbished condition | One condition per column |
| PON face | Exactly 2 PON ports, standard name, wavelength pair, optical budget class with dB | Reject a 4-port price presented as a two-port price |
| Optics form | Fixed optics or pluggable SFP+, and whether the optic is in the price | Do not compare a bare cage with a loaded cage |
| Uplink | GE, 10GE or both, copper or fiber, included transceiver or not | Switching capacity of a tiny pizza box is still a stated figure, not an assumed fabric |
| Power | -48 VDC, 100-240 VAC, or both, and whether the rectifier is included | A DC chassis priced without a rectifier is a different offer |
| Environment | Operating temperature and whether an outdoor enclosure is in scope | Ingress protection applies to the cabinet, not automatically to the chassis |
| Software | Local CLI, EMS license, OMCI, DBA, FEC, AES, and any subscription | License term is a cost line |
| Commercial | Currency, per chassis or whole order, Incoterm, freight, duties, lead time | Normalize before reading the unit figure |
Costs that stay outside the chassis line
Splitters, SC/APC patch cords, ONTs, rack nuts, a spare fan, training and a site survey are separate unless the plant writes them in. Insertion loss of the splitter and return loss of the cord are cord-and-splitter questions. Dispersion is a fiber-plant question for the reach you claim, not a number this desk calculates. Connector mating cycle life belongs on the patch-cord drawing if you care about repeated test mating.
Buyer scenario for a two-port buy. A campus network lead needed two chassis for two buildings that share one upstream switch. Background: each building had a 1:32 splitter and a GE uplink back to a closet. Process: the brief froze 2 PON ports, GE uplink, 100-240 VAC and indoor 0 °C to 50 °C as questions for the plant to confirm, and it excluded ONTs. Result: three plants returned two-port prices with optics called out, so the GE SFP was visible instead of being missing on one offer.
Read the inquiry rows before you send the sheet, and use the RFQ page when the cells are filled.
Evidence questions on a two-port quotation
Which document is tied to the model?
Ask for a current datasheet that prints the same model string as the quotation. A family brochure that lists 2, 4 and 8 ports does not prove the two-port SKU has the same optical budget. Transmit power and receiver sensitivity must be on the port that is being sold.
What does a wavelength match fail to prove?
Two products can both cite 1490 nm downstream and still differ in line rate, FEC and OMCI behaviour. Host compatibility is a test against the ONT list you wrote, or it remains an open deviation. Do not accept “compatible with EPON” as a substitute for the ONT models.
How should deviations be shown?
Ask the plant to split the reply into compliant lines, deviations and optional alternatives. An alternative 4-port chassis can be offered beside the 2 pon port olt line. It cannot replace that line in the comparison column.
What inspection happens after arrival?
Plan a document check, a power-up on the stated input, a read of optical power if the port reports it, and a management login. Measurement accuracy of that reading stays a supplier statement. Calibration traceability, if you need it, is a request for the plant’s test note, not a certificate from this website.
Send the two-port sheet for factory quotes
Include standard, wavelengths, budget class, power, quantity and destination. Optional budget needs currency and a per-chassis or whole-order basis. High-end, mid-range, budget or undecided is a preference about documentation and commercial posture, not a grade this desk has verified.
Files such as a port map can be described in the box. The form has no upload control. A later email can carry the file if the review asks for it.
