How the desk works
LinkScope Sourcing 13
LinkScope Sourcing 13 is an independent sourcing partner for buyers who need industrial Ethernet switches compared on one written brief. The service name is the desk. It is not a switch brand, and it is not a factory floor.
- You send port count, speed, power, quantity, destination, and timing.
- The desk asks factories for the exact model behind each price.
- You compare replies after exclusions and evidence sit on the same rows.
What the desk will and will not put in writing
A quotation request can carry switching capacity, forwarding rate, Power over Ethernet budget, ingress protection, rack unit or DIN rail, and the 100 ohm copper question. Those cells stay questions until a factory ties them to a model row. IEEE 802.3 can suggest the question. It does not authorize the unit.
The desk will not publish a saving percentage, a warehouse count, or an authorized-distributor badge. There is no audited factory list on this site. A supplier preference for high-end, mid-range, budget-friendly, or undecided is your buying note. It is not a grade we verified.
Managed gear and unmanaged gear stay in separate comparisons when the job needs monitoring. A managed path can add alarms and VLANs. An unmanaged path can suit a fixed star. Substituting one for the other is a deviation, not a silent equivalent. New and refurbished condition also stay on separate lines when you allow both.
For a four-port cabinet, an 8 Gbps non-blocking question and a 1.488 Mpps forwarding question at 64-byte frames are useful checks. For sixteen 1 Gb/s ports the same method points near 32 Gbps and 23.8 Mpps. The desk records the arithmetic so factories answer it. The desk does not measure the frames.
Procurement scenario: a buyer who arrived with three catalog screenshots
Background: the screenshots showed different port counts, one PoE claim, and no temperature row. Process: LinkScope Sourcing 13 rewrote the note into model, port speed, input voltage, quantity, US destination, and a request for the datasheet page. Result: factories either matched those cells or marked a gap. The screenshots were kept as context and were not treated as evidence.
Related reading sits on the procurement brief. Inquiry names sit on the switch cards.
Questions about the desk itself
Do you ship from your own shelves?
No. Factories or their nominated sellers ship against the quotation you accept. This page coordinates the request and the comparison.
Can you sign a compatibility statement?
No. Host behavior, ring protocol, and optical budget need the exact proposed pair. A connector photo is not that test. Receiver sensitivity and transmit power belong on the optic datasheet when an SFP is in scope.
What does a complete note contain?
Specifications, quantity, destination, and delivery timing, plus the evidence list you want back. An optional budget can name currency and a per-unit or whole-order basis.
Start with the written brief
Paste the port map into the box. There is no attachment slot. A short note with the open cells marked is enough to request factory quotations.
