Industrial optical switch briefs before factory quotations

LinkScope Sourcing 06 collects an industrial optical switch request from a US buyer and asks factories to price the same port map, wavelength, and destination. The desk does not hold chassis inventory and it does not publish a measured insertion loss for any model.

  • Port map, such as 1x2, 1x4, 1x8, or 2x2, plus latching or non-latching
  • Wavelength window, fiber mode, connector, and the optical budget the link must close
  • Quantity in pieces, the US destination, and the timing the buyer can actually accept

Quote lines that must share one basis

A headline unit price is not comparable until the factory names the exact model and splits the extras. Use this table as the buyer worksheet. Every number below is a question to send, not a rating this desk has already measured.

LineBuyer writesFactory must answer
Optical path 1310 nm, 1550 nm, or a stated band such as 1260-1650 nm Insertion loss and return loss at the wavelengths the buyer named, with the test method
Power and reach Transmit power, receiver sensitivity, and the link reach the path must cover Whether the switch loss still leaves the optical budget closed, including connectors
Control Manual, TTL, RS-232, Ethernet, or latching with no holding power Supply voltage, current, and which diagnostics the proposed unit actually reports
Commercial Piece count, currency, Incoterm, and US destination Unit price, freight, duties, lead time, and every exclusion on its own line

Dispersion and wavelength planning belong to the fiber plant. They do not transfer from an ITU-T recommendation page onto an unnamed switch. ITU-T G.652 is a question source for the installed fiber, not a certificate for the chassis a factory later proposes.

Read the procurement brief before you freeze the port map, then send the note from the contact page.

Who writes which part of the brief

Telecom procurement

Owns quantity, destination, currency, and the optional target budget. A budget can be per piece or for the whole order. It does not replace the wavelength or the connector.

Optical engineer

Owns fiber mode, reach, connector polish, and the optical budget. A 1x2 protection path and a 1x8 monitoring tree are different drawings. They should not share one loss figure.

Quality reviewer

Asks for the current datasheet, the test condition, and any FCC or NRTL file that applies to the exact proposed item. A family brochure is not that file.

Worked path, not a completed job: a data-center buyer protecting a 10 km single-mode span lists a 1x2 latching switch, 1550 nm, LC/UPC, and a loss target the link can spare. The desk sends that text to factories. Each reply names a model. The buyer then checks insertion loss against the spare optical budget. No factory is accepted on this page, and no saving is stated.

Questions that change the quotation

What should be ready before factories are asked?

Write the port map, wavelength, fiber mode, connector, quantity, US destination, and requested timing. Mark unknown fields as unknown. A blank optical budget should stay blank rather than copy a number from another project.

How does supplier matching work here?

The desk is an independent sourcing partner. It forwards the same brief and asks each factory to identify manufacturer, model, and deviations. Matching is a correspondence step. It is not an audited factory visit and it is not a stock promise.

Single-mode or multimode?

Single-mode fiber can support a longer reach when the optics and the plant are designed for it. Multimode can suit a short data-center jumper when the switch, the fiber, and the connectors agree. The two plants are not interchangeable because a connector photo looks similar. State the mode the installed cable already uses.

Can a compatible unit replace a named model?

A compatible alternative may widen the supplier list when the host, the control pinout, and the loss are checked on that exact unit. An OEM-coded label may track a vendor support policy more directly. Either choice needs the datasheet of the unit being offered, not a catalog family name.

Send the industrial optical switch brief

Include port count, wavelength, connector, piece quantity, and the US site that will receive the goods. Optional budget and a high-end, mid-range, budget-friendly, or undecided preference can travel with the note. They are buyer preferences, not a verified rank.
