2 port sfp ethernet switch
A 2 port sfp ethernet switch quotation collapses when the cages are described and the optics are not. LinkScope Sourcing 15 records the copper side, the two SFP cages, the reach, and the host coding as separate cells so factories answer the same grid.
Say whether the copper face is 10/100, 10/100/1000, or absent. A two-cage unit used as a media converter is a different line from a small access switch with extra RJ45 ports.
Ask if both cages are 1 Gb/s SFP, if either is SFP+, and whether they accept the same coding. Do not assume a cage labeled SFP will run a 10 Gb/s module.
Wavelength, fiber mode, and reach belong on the optic line: 850 nm multimode, 1310 nm single-mode, and a stated kilometer figure. The cage price is not the link price.
Record the switch power input. If the copper ports must source Power over Ethernet, that watt budget is another cell. Many two-SFP edge units do not source PoE at all.
Evidence ledger for a two-cage unit
Each row is copied from the supplier reply and tied to one model number. A family photo of cages does not fill the row.
OEM-coded optics can match a platform support policy more directly. Compatible optics can widen the supplier set when the exact host accepts them. Ask the switch vendor and the optic vendor which combination they will stand behind. This desk does not run the interoperability test.
Request transmit power and receiver sensitivity for the named optic, then compare them with the plant loss, including connectors and splices. Insertion loss on the patch cord is part of that sum. A nominal reach of 10 km is not a measured link.
State CLI, web, or unmanaged. A two-port unit in a camera hut may not need SNMP. The same unit feeding a monitored ring usually does. Write the choice so the price does not hide a license.
Ask for the operating range on the named model. An outdoor cabinet is a different environment from a wiring closet. Do not borrow an industrial range from a sibling SKU.
Request the FCC authorization identifier and any NRTL file that the supplier says covers this model for US delivery. Applicability stays with that model. A standard overview is a question list, not a certificate.
Compatibility questions that change the quotation
- Which fiber is already in the duct, single-mode or multimode, and which connector faces the cage, LC or SC? Single-mode supports longer reach when the optic and the fiber agree. Multimode can suit a short building link when the transceiver wavelength matches the plant. Mixing them is a failed link, not a discount.
- Does the host switch, if this unit uplinks into a larger chassis, accept the optic coding you intend to buy? Compatible modules need an exact-host check. A matching cage name is not that check.
- Are the two cages independent forwarding ports, or does the silicon share a pipe that drops below line rate when both are full? Ask for the forwarding rate and the frame size used to publish it.
- What is excluded: rail kit, power cord, optics, fiber jumpers, licenses, and configuration time? Freight and duties follow the US destination you write, not a warehouse the supplier assumes.
- If the offer is refurbished, what condition, warranty months, and license state come with the serial number? New and refurbished stay in separate columns.
A complete two-cage reply also names switching capacity in Gb/s and forwarding rate in Mpps using 64-byte frames. Copper may be 100BASE-TX or 1000BASE-T. If Power over Ethernet is present, split 802.3af at 15.4 W from 802.3at at 30 W and write the chassis watt budget beside them. The optic line carries wavelength, transmit power in dBm, receiver sensitivity in dBm, optical budget, and insertion loss. Return loss belongs with the connector. VSWR is an RF figure and stays off this sheet unless a coax converter is a separate line. Height is a rack unit, often 1U, or a desktop shell with depth in millimeters.
Port cards for the wider family are on the inquiry list. The packet itself goes through the brief form.
Hand the two-cage grid to factories
Paste the copper count, both cage speeds, the optic wavelength and reach, quantity, destination, and timing. There is no file upload on this form. Put the grid in the requirement field so every factory sees the same text.
