Shop LINK-PP compatible 800G optics in QSFP-DD and OSFP for AI/HPC fabrics, spine/leaf, and next-gen DCI. This category groups MSA-aligned 800G modules—SR8, DR8, 2×FR4, 2×LR4, XDR8, and related reaches—coded for Cisco, Arista, Juniper, NVIDIA, and other major platforms. Start from the parent optics hub for lower rates, step through 400G QSFP-DD / OSFP when planning mixed generations, or open a Cisco compatible PN when the OEM part number is already known. Match host cage (QSFP-DD vs OSFP), finned vs flat top, fiber plant, and rated reach on each product page before ordering.
Frequently asked questions
01.Which 800G form factors does this category cover?
This store lists LINK-PP compatible
800G QSFP-DD and
OSFP modules for 800 Gigabit Ethernet and related AI/HPC interconnects. Use the on-page filters to narrow by form factor and reach, or return to the parent
optics hub when you still need 1G–400G rates.
02.How do I choose SR8 vs DR8 vs 2×FR4 vs 2×LR4 for 800G?
Match media and distance first: SR8 for short multimode (typically tens of meters on OM4 with MPO-16 or dual MPO-12), DR8 for about 500 m parallel single-mode, 2×FR4 for about 2 km dual duplex LC single-mode, and 2×LR4 for about 10 km dual duplex LC single-mode. Confirm connector map, APC vs UPC polish, and power class on the product page.
03.What is the difference between QSFP-DD and OSFP at 800G?
Both can carry 800G with eight electrical lanes, but the mechanical cage and thermal envelope differ. QSFP-DD is common on many Ethernet switches; OSFP is widely used on NVIDIA and other AI/HPC platforms and may be finned-top or flat-top. Always match the module form factor—and heat-sink style—to the host port; adapters are SKU-specific.
04.Are these 800G modules coded for Cisco, Arista, Juniper, and NVIDIA?
Yes—select the Compatible PN that matches your OEM platform. LINK-PP 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) and open the PDP that lists your switch or NIC part number.
05.Do LINK-PP 800G optics support DOM and host FEC?
Most optical 800G SKUs support digital optical monitoring (DOM/DDM) for temperature, voltage, and Tx/Rx power per the datasheet. 800G PAM4 links typically rely on host FEC as specified by IEEE / MSA for the optic type—check the individual PDP for DOM support, FEC expectations, temperature range, and rated reach before you order.
