200/400/800G Transceiver Modules

200/400/800G Transceiver Modules

Shop LINK-PP compatible 200G–800G optical transceivers in QSFP56, QSFP-DD, and OSFP for AI/HPC fabrics, dense spine/leaf, and DCI. This high-rate hub groups MSA-aligned modules across the 200/400/800G band—coded for Cisco, Arista, Juniper, NVIDIA, and other major platforms. Open a child speed store when you know the generation: 200G QSFP-DD / QSFP56, 400G QSFP-DD / OSFP, or 800G QSFP-DD / OSFP. Match host cage, finned vs flat top, fiber plant, and rated reach on each product page before ordering.

Frequently asked questions

01.Which rates does this 200/400/800G hub cover?
This high-rate hub lists LINK-PP compatible optics across 200G, 400G, and 800G in QSFP56, QSFP-DD, and OSFP packages. Jump to 200G QSFP-DD / QSFP56, 400G QSFP-DD / OSFP, or 800G QSFP-DD / OSFP when you already know the generation.
02.How do I choose 200G vs 400G vs 800G?
Match switch ASIC port speed and fabric generation first: 200G QSFP56 is common on transitional leafs, 400G QSFP-DD/OSFP dominates many Ethernet spines, and 800G QSFP-DD/OSFP targets AI/HPC and next-gen DCI. Confirm whether the host expects NRZ or PAM4 lanes and which FEC mode the optic type requires.
03.What is the difference between QSFP56, QSFP-DD, and OSFP here?
QSFP56 typically carries 200G; QSFP-DD doubles density for 400G/800G Ethernet on many switches; OSFP is a larger package common on some platforms and InfiniBand/Ethernet AI fabrics. Always match the module form factor and lid style (finned vs flat) to the host cage—adapters are SKU-specific.
04.Are these high-rate modules coded for Cisco, Arista, Juniper, and NVIDIA?
Yes—select the Compatible PN that matches your OEM platform. LINK-PP 200G–800G modules follow MSA electrical/optical specs and are EEPROM-coded for the target brand. Browse the Cisco compatible hub (or Arista / Juniper / NVIDIA hubs) when the OEM part number is already known.
05.Do LINK-PP 200G–800G optics support DOM and host FEC?
Most optical SKUs support digital optical monitoring (DOM/DDM) for temperature, voltage, and Tx/Rx power per the datasheet. PAM4 200G/400G/800G links typically rely on host FEC as specified by IEEE / MSA for the optic type—check the PDP for DOM, FEC expectations, temperature range, and rated reach before ordering.
