Scope and inclusion

This edition covers 116 modules and named module families with 800G aggregate capacity, from 11 makers: switch and router vendors (Cisco, Arista, Juniper, NVIDIA), optics makers (Coherent, InnoLight, Eoptolink, Accelink, Lumentum, Source Photonics) and FS, which builds and codes modules for third-party hosts. Twin-port 2x400G modules and 800ZR/ZR+ coherent pluggables are included; cables (DAC, ACC, AEC, AOC) and 1.6T modules are not. Named families appear when the maker describes a module without publishing an ordering code; their part-number field stays empty.

Each record carries at least three sourced specification fields beyond its name, URL and summary. Package, reach, fiber, connector, power, processing and evidence status are collected as separate fields.

Source priority and collection

Every value comes from a first-party document: maker data sheets and product pages, ordering guides, Juniper’s Hardware Compatibility Tool, NVIDIA’s LinkX documentation, and vendor-authored demonstration sheets hosted by OIF. The register below lists all 79 documents. Trade press and reseller listings are not used for any field.

Every filled field maps to a source URL through the record’s sources[].fields list. Each source has an access date. Each record’s verification date is the date its cited specification was checked, rather than a product release or stock-verification date. Empty fields mean the cited evidence did not resolve the value.

How to read the ratings

Reach: meters throughout. Multimode reach follows the best explicitly supported fiber grade; the shorter reach on another grade remains in link conditions. Coherent reach is kept with the amplified DWDM condition. Optical budget, patch panels and host qualification still determine the usable link.

Power: maximum and typical are separate fields. A “less than” rating is stored at its upper boundary, with the inequality kept in link conditions. Cisco OSFP records keep the VDM diagnostic condition and use the upper value when a range is given. Arista publishes one 16 W ceiling per 800G class, and that class value is recorded.

Processing: filled only when a supplier explicitly describes DSP, coherent DSP or LPO operation. Host FEC, PAM4 signaling and silicon photonics alone do not establish whether an in-module DSP exists. Missing architecture stays empty.

Evidence status: Catalogued means the maker lists the module on a live product, ordering or compatibility page. Demonstrated means the evidence is an exhibition specification; its event year appears in the source title. Price, stock and delivery come with a quote.

Conflicts preserved

Cisco QDD-800G-VR8 has conflicting connector-polish wording, so its connector field stays empty. NVIDIA MMS4X00-NM-T uses the reach in its Key Features and records the conflicting introduction sentence. NVIDIA MMS4X90-NR follows its 10 km title and specification table; its introduction still carries 2xFR4 text. Coherent FTCE3316E1PCL is an OIF 800ZR part whose parameter table prints 1,000 km; the record uses the 120 km 800ZR reach from the same page, in line with its ZR+ sibling rated 750 km. Several Coherent coherent-optics pages disagree between header and table on band, Tx power or ZR/ZR+ naming; each record states which value it uses.

Related modules and shortlists

Shortlists use package, explicit LPO or coherent processing, and published reach. Related modules match package and reach first, then interface, and favour another maker when the rest is equal, so every page gives you a second source to quote.

Corrections and commercial placement

Send corrections to hello@800gtransceivers.com with a public specification. A verified change updates the affected record and date. Sponsored placements are labelled and do not alter specifications or table sorting. No record has paid placement at launch.

Field definitions

Maker
Supplier named on the cited product page.
Part number
Published ordering identifier. Empty for a named module family without a public SKU.
Form factor
Mechanical package; QSFP-DD includes QSFP-DD800.
Optical interface
Vendor interface designation. A dual-port module has 800G aggregate capacity.
Reach m
Advertised upper reach in meters. See link conditions; coherent reach requires an engineered line system.
Fiber
Optical medium. MMF reaches use the best specified fiber grade.
Connector
Published optical connector configuration and polish where explicitly stated.
Max power W
Maximum consumption in watts. A strict less-than limit is recorded at its upper boundary; notes preserve the inequality and conditions.
Typical power W
Typical consumption in watts, kept separate from the maximum. Notes preserve strict less-than wording.
Processing
DSP, LPO or coherent optics only when explicitly identified; FEC on the host does not establish DSP absence.
Evidence status
Catalogued means a live supplier product or ordering page. Demonstrated means an exhibition specification. Neither establishes stock or a delivery date.
Case temperature
Published operating case temperature range in degrees Celsius.
Link conditions
Fiber grade, thermal modes, connector conflicts or line-system conditions attached to the specification.
