Optics Transceivers | SFP Modules

Browse LINK-PP compatible optical transceivers spanning 1G SFP through 800G QSFP-DD and OSFP. This hub groups MSA-aligned modules by rate and form factor—SFP/SFP+, SFP28, QSFP+/QSFP28, and QSFP-DD/OSFP—coded for Cisco, Arista, Juniper, NVIDIA, and other major platforms. Jump to 10G SFP+, 100G QSFP28, or 400G QSFP-DD / OSFP when you know the speed, or open a Cisco compatible PN when you already know the OEM part number. Each listing follows IEEE / MSA specs for the stated reach and media—confirm fiber type, connector, and DOM on the product page before ordering.

Frequently asked questions

01.What speeds and form factors does this optics hub cover?
This category spans LINK-PP compatible optics from 1G SFP up through 25G SFP28, 40G/100G QSFP+/QSFP28, and 200G/400G/800G QSFP-DD and OSFP—plus related DAC/AOC cables where listed. Use the on-page circle filters or open a speed store such as 100G QSFP28 to narrow by rate and package.
02.How do I choose the right optical transceiver?
Start with port speed and cage type on your switch (SFP+, QSFP28, QSFP-DD, OSFP), then match media and distance—short multimode (SR/SR4/SR8), mid-reach CWDM4/FR4/DR4, or longer single-mode LR/LR4. Confirm wavelength, connector (LC vs MPO), and power class on the product page so the module fits your fiber plant.
03.Are modules coded for Cisco, Arista, Juniper, and NVIDIA?
Yes—select the Compatible PN that matches your OEM platform. LINK-PP modules follow MSA electrical/optical specs and are EEPROM-coded for the target brand. Browse the Cisco compatible hub (or Arista / Juniper / NVIDIA hubs) and open the PDP that lists your switch part number.
04.What is the difference between SFP+, QSFP28, and QSFP-DD?
SFP+ is a single-channel 10G package; SFP28 scales that form to 25G. QSFP28 carries four lanes for 100G in one cage. QSFP-DD (and OSFP) doubles density for 400G/800G with more electrical lanes. Always match the module form factor to the host port—adapters and breakouts are SKU-specific.
05.Do LINK-PP optics include DOM / DDM digital diagnostics?
Most optical SKUs support digital optical monitoring (DOM/DDM) for temperature, voltage, and Tx/Rx power per the product datasheet; copper or special-purpose modules may differ. Check the individual PDP specifications for DOM support, temperature range, and rated reach before you order.
