NVIDIA 100G / 400G multimode links and fiber connections
Compare the interface, fiber grade and connection layout. These parts serve different links; they are not a ready-to-connect kit.
| Exact model | Selection condition |
|---|---|
| MMA1B00-C100D980-9I149-00CS00 | 100GbE QSFP28 SR4, MPO/UPC: up to 70 m OM3 or 100 m OM4. |
| MMA4Z00-NS400-T980-9I51S-F4NS00 | 400GbE single-port flat-top OSFP, MPO-12/APC: up to 30 m OM3 or 50 m OM4; verify cage cooling. |
| MFP7E10-N003980-9I73U-000003 | 3 m straight crossover: four-channel MPO/APC at both ends. |
| MFP7E20-N003980-9I571-00N003 | 3 m 1:2 splitter crossover: four-channel MPO/APC to two two-channel MPO/APC branches. |
The 100G module uses UPC; the listed 400G module and E10 / E20 assemblies use APC. Do not mate APC to UPC. Provide both devices and ports, operating mode, fiber grade and length.
Filters use published specifications. Confirm host and cabling requirements when requesting a quote.
Selection and procurement FAQ
Independent B2B sourcing context
Source optical transceivers by link requirements
SwitchInfra helps buyers shortlist optical transceiver families and current catalog entries by data rate, form factor, reach, fiber type, wavelength, and intended host platform.
A category or product listing is not a compatibility, stock, delivery, warranty, or performance guarantee. Confirm the exact SKU, host platform, software or firmware context, and commercial terms in an item-specific RFQ.
Compare before RFQ
- Data rate, form factor, and lane configuration
- Reach, fiber type, wavelength, and connector
- Host platform, port requirements, and coding request
- Link budget, FEC, breakout, and cabling context
Is SwitchInfra an official FS.com storefront?
No. SwitchInfra is an independent sourcing and evaluation platform and should not be represented as an official FS.com storefront or manufacturer site.
Can this page confirm transceiver compatibility?
No. Compatibility must be checked against the exact transceiver SKU, host platform, port, software or firmware version, link design, and requested coding before purchase.
Representative catalog entries
These links are rendered from the current catalog. Item-level commercial and technical details still require verification.
400G QSFP-DD Optical Transceivers
Compare two current SwitchInfra catalogue entries for parallel single-mode links. Both are listed as used; confirm the offered unit's condition and test evidence before ordering. These are different reach options, not interchangeable parts for every host or fiber installation.
| Model | Documented optical scope | Selection note |
|---|---|---|
| Arista QDD-400G-XDR4 | 400G QSFP-DD XDR4, MPO-12 APC, parallel single-mode fiber, up to 2 km | Confirm target-host support, fiber polarity and any 4x100G breakout configuration. |
| Intel SPTSHP2PMCDF | 400G DR4 QSFP-DD, MPO connector, 500 m single-mode reach | Intel lists this product as retired/discontinued. Confirm lifecycle suitability, unit testing and seller support. |
Specifications are grounded in the Arista transceiver datasheet and Intel ordering information. Manufacturer specifications do not certify an individual used unit or its compatibility with your equipment.
Can I Use Existing Duplex LC Fiber?
These two entries use parallel-fiber MPO connections. Do not select them on speed and distance alone or assume they fit a duplex LC installation. Include the installed fiber type, connector, polarity and optical budget in your RFQ.
Can a 400G Port Be Split Into Four 100G Links?
Arista documents a 4x100G-FR configuration for QDD-400G-XDR4. The host port mode, software, remote optics and breakout fiber assembly must also support the intended link. Do not infer this from a QSFP-DD cage alone.
What Should I Request For Used Optics?
Request the exact part and hardware revision, offered condition, serial-level traceability, available inspection and link-test records, and the applicable repair or replacement terms. Confirm what was tested, on which host and at which speed. Catalogue stock labels are not unit-level test evidence.
What Seller Warranty And Return Terms Are Published?
SwitchInfra's published seller policy (2026-10-08.v0.3.5) lists 3 months for used equipment. Seller warranty is separate from manufacturer warranty or service entitlement.
The matrix below applies to new transactions confirmed under this version. Warranty starts on actual customer receipt. The product category, responsible party, scope, costs, return location, replacement condition and subsequent coverage are recorded in the quotation or order. Existing transactions retain their valid original terms.
Most eligible products allow a commercial return request within 30 days of actual receipt. Eligibility for the exact SKU is disclosed before confirmation and follows its valid terms. A request made in time does not expire while awaiting review. Missing delivery evidence is reviewed manually; shipment dates do not replace receipt dates.
Review the seller warranty policy and return eligibility and product-issue process before accepting a quote. The policy is not proof of stock or unit-level testing.
Can I Request Delivery To Africa Or The Middle East?
Send the destination country and city, required quantity and arrival date with your part list. SwitchInfra assesses delivery for the exact order; this page does not promise local stock, a fixed transit time or import charges included. The written quote should state dispatch origin, freight, customs responsibility and the warranty provider, duration and return-shipping arrangements.
