400G QSFP-DD/OSFP/QSFP112

400G QSFP-DD/OSFP/QSFP112

Shop LINK-PP compatible 400G optics in QSFP-DD, OSFP, and QSFP112 form factors for data-center spine/leaf and DCI links. This category groups MSA-aligned 400GBASE modules—SR8, DR4, FR4, XDR4/PLR4, LR4, and related reaches—coded for Cisco, Arista, Juniper, NVIDIA, and other major platforms. Start from the parent optics hub when you still need lower rates, jump to 100G QSFP28 for breakout planning, or open a Cisco compatible PN when the OEM part number is already known. Match host cage, fiber type (MMF vs SMF), connector (MPO vs duplex LC), and rated reach on each product page before ordering.

Frequently asked questions

01.Which 400G form factors does this category cover?
This store lists LINK-PP compatible 400G modules in QSFP-DD, OSFP, and QSFP112 packages for 400G Ethernet and related interconnects. Use the on-page circle filters to narrow by form factor and reach, or return to the parent optics hub when you still need 1G–100G rates.
02.How do I choose SR8 vs DR4 vs FR4 vs LR4?
Match media and distance first: SR8 for short multimode (typically up to about 100 m on OM4 with MPO-16), DR4 for about 500 m parallel single-mode (MPO-12), FR4 for about 2 km duplex LC single-mode, and LR4 for about 10 km duplex LC single-mode. Confirm wavelength, connector polish, and power class on the product page so the optic fits your fiber plant.
03.What is the difference between QSFP-DD and OSFP for 400G?
Both carry 400G with eight electrical lanes, but the mechanical cage differs: QSFP-DD is the denser double-density QSFP family used on many Ethernet switches, while OSFP is a larger package common on some platforms and AI/HPC fabrics. Always match the module form factor to the host port—adapters and breakouts are SKU-specific.
04.Are these 400G modules coded for Cisco, Arista, Juniper, and NVIDIA?
Yes—select the Compatible PN that matches your OEM platform. LINK-PP 400G 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.
05.Do LINK-PP 400G optics support DOM and host FEC?
Most optical 400G SKUs support digital optical monitoring (DOM/DDM) for temperature, voltage, and Tx/Rx power per the datasheet. 400G 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.
