Which switches use OSFP vs QSFP-DD 800G ports

800G ports are not interchangeable by form factor. Before you order an OSFP SR8 module, confirm that the physical cage on your switch or NIC is OSFP.

  • OSFP 800G ports → use an OSFP module such as 800G OSFP SR8.
  • QSFP-DD800 ports → use a QSFP-DD800 module instead. If your platform is QSFP-DD800 and you need the same multimode reach class, see 800G QSFP-DD SR8 (listed single MPO-16/APC, 100m OM4 / 60m OM3, ≤15W).

We do not claim support for any specific switch model on this page. Check your platform documentation for the port type, then send us the five items below so coding can be checked for that host.

Cisco and Arista compatibility: how we check coding

Many buyers search for an 800G OSFP SR8 compatible transceiver supplier for Cisco or Arista environments. YYGL Optical can supply the OSFP SR8 module above and check coding for the host you name. We are a third-party optics supplier; we are not Cisco, Arista, or any other switch brand, and we do not claim affiliation with them.

Compatibility depends on the host platform. Please share your switch model, software version, module type, link distance and fiber type so we can check coding and compatibility before you order.

What to send us

Include these five items in your RFQ (or email):

  1. Switch (or NIC) model
  2. Software / firmware version (as shown on the device)
  3. Module type you need (for example 800G OSFP SR8)
  4. Link distance
  5. Fiber type (OM3 / OM4 multimode, or single-mode if you are evaluating a different reach class)

Optional but helpful: quantity, whether you need finned-top or flat-top OSFP, and any OEM part number you are replacing (we use that only as a reference for the RFQ — we make no equivalence claim until confirmed in writing).

What we do with it

After we receive the five items, we:

  • Confirm that the requested form factor and reach class match an available SKU (for short multimode OSFP links, typically YY-OSFP-SR8-100M)
  • Check coding requirements for the host platform you named
  • Confirm coding and compatibility in writing before shipment

Lead time, MOQ, stock, and sample availability vary by project — ask us when you send the RFQ. We do not publish universal “works in every Cisco / Arista 800G port” claims on this page.

Also used with NVIDIA Mellanox, Juniper and Dell platforms

The same coding-check process applies when the host is NVIDIA Mellanox, Juniper, or Dell. Brands we discuss for compatibility checks on this site are limited to Cisco, Arista, NVIDIA Mellanox, Juniper, and Dell.

Send the same five items. We will check coding for that platform before you order. For a deeper buyer checklist aimed at third-party 800G in NVIDIA Mellanox networks, see Third-Party 800G Transceivers for NVIDIA Mellanox Networks: What to Check Before You Buy.

FAQ

Is an 800G OSFP SR8 the same as a QSFP-DD SR8?

No. Both can be 800G SR8-class multimode optics, but the form factor and connector differ. Our OSFP SR8 listing uses dual MPO-12/APC in an OSFP package. Our QSFP-DD SR8 listing uses a single MPO-16/APC in a QSFP-DD800 package. Order the type that matches your port.

Are YYGL modules “compatible with Cisco / Arista” out of the box?

Compatibility depends on the host platform. Please share your switch model, software version, module type, link distance and fiber type so we can check coding and compatibility before you order. We do not promise universal or guaranteed compatibility for every chassis and software release.

What reach does the 800G OSFP SR8 support?

Per the product listing: 100m over OM4 multimode fiber, or 60m over OM3, at 850nm, with dual MPO-12/APC. For shorter multimode links see OSFP VR8; for up to 2km parallel single-mode see OSFP DR8+.
