DESK METHOD
LinkScope Sourcing 01
LinkScope Sourcing 01 coordinates factory search and quotation comparison for business buyers of fiber optic equipment. The work starts when a buyer sends a module requirement. It ends when the replies can be read on one scope, or when the brief is too open to send.
What the desk does with a brief
-
Normalize the optical line
The coordinator rewrites the request so interface, data rate, wavelength, fiber mode, reach, connector, diagnostics, temperature range, and host are either filled or marked unknown. Unknown is acceptable. A guessed wavelength is not. If the buyer says PAM4 without a lane rate, the brief goes back before any factory is contacted.
-
Search factories against that line
Outreach asks for a named manufacturer, a named model, and a current datasheet. A catalog family is not accepted as the answer. The desk does not claim a plant relationship, a distribution appointment, or a prior audit. Any such statement would have to come from the supplier, about that supplier, and stay in the quotation file.
-
Compare scope, not a headline figure
Replies are set beside quantity, currency, per-module or whole-order basis, Incoterm, freight, coding, accessories, and exclusions. An optional target budget is recorded with its currency and basis. High-end, mid-range, budget, or undecided is stored as the buyer preference. It is not converted into a supplier medal.
-
Hand the evidence list back
The buyer receives the questions that remained open: host software release, FEC mode, optical budget arithmetic, laser-class paperwork, and any FCC or NRTL question that applies to the exact model. This site does not convert those open items into a pass.
Role boundaries buyers ask about
The desk is not the manufacturer
Module construction, wafer or TO-can process, burn-in, and firmware remain with the factory that quotes. LinkScope Sourcing 01 does not operate that process and does not publish a capacity number, a founding year, or a client count. Those figures are absent because they are not evidenced here, not because they were rounded.
The desk is not the network operator
Link design, loss budgets signed by an engineer of record, and acceptance on a live route stay with the buyer or the buyer engineer. The desk can list the inputs those people need: transmit power minimum, receiver sensitivity, connector loss, and fiber attenuation at the wavelength in use. It does not sign the link.
Standards are question sources
ITU-T optical-fibre recommendations and IEEE 802.3 interface names help a buyer phrase a question. A recommendation page is not a certificate for a transceiver that has not been identified. When a supplier claims conformance, the document has to name the model and the revision.
Commercial notes stay conditional
No paired quotations are stored for this product family, so the site does not state a saving against a market figure. Buyers who already hold a quotation can still send it as context. The desk will not treat that private paper as a public benchmark.
Fiber choice the brief has to name
Single-mode and multimode are both legitimate plants, and they are not substitutes. Buyers write single-mode when the route is a campus or metro length and the wavelength plan is part of the request. They write multimode when the trunk is already OM3 or OM4 and the module is an 850 nm short-reach part. LinkScope Sourcing 01 does not choose for them. A brief that names neither the fiber designation nor the wavelength is returned before outreach.
A line that names 100 Gbit/s without a lane plan is still open. Parallel 100GBASE-SR4 is commonly published as about 70 m on OM3 and about 100 m on OM4 at 850 nm over MPO. A duplex 100GBASE-LR4 class is commonly published near 10 km on single-mode fiber around 1310 nm. Those class names are copied from public interface descriptions. This desk did not measure the route. For the optical budget, record transmit power minimum and receiver sensitivity in dBm, then subtract insertion loss and fiber attenuation at that wavelength. Worked arithmetic, not a quotation: -4.5 dBm minus -11.2 dBm leaves 6.7 dB before connectors. If each mated pair is allowed 0.35 dB and the path has four pairs, connector insertion loss is 1.4 dB. A dispersion penalty, when the datasheet prints one, stays beside the reach class. Return loss of the optical port is a different line from connector insertion loss. Temperature stays on the same row: 0 °C to 70 °C commercial is not -40 °C to 85 °C industrial.
Read the requirement checklist for the field order, or the procurement note for the evidence table used in outreach.
Request factory quotes through the same form
Share the host, the rate, the fiber plant, the quantity, and the US destination. If a number is still open, write unknown. The coordinator will mark it as a supplier question rather than fill it in.
