# Endpoint requirements record

Record both hosts, exact module identities, port modes and the requirements that must agree across a link.

Revision 2026-11-01. Planning inputs only; unresolved conditions are not approval.

## Connection identity

Record the actual installed hardware and software. A form factor or optical-standard name alone does not establish compatibility.

- **Project / link ID / date / engineer:**

- **A: device, port and software release:**

- **Z: device, port and software release:**

- **A: module marking, revision and serial:**

- **Z: module marking, revision and serial:**

## Electrical and optical requirements

Keep electrical host FEC separate from optical line FEC. Use the exact supported application and lane mapping at each endpoint.

- **Protocol and intended payload rate:**

- **A and Z host application / electrical lane rate and count:**

- **A and Z host FEC setting and source:**

- **Optical interface / lane mapping / line FEC:**

- **Connector, fiber count, media and reach requirement:**

- **Host power class, cooling and temperature requirements:**

## Evidence and unresolved conditions

No threshold or compatibility result is implied by completing this record.

- **Applicable documents: title, revision, page and date:**

- **Validated host / module combination and test evidence:**

- **Peer interoperability conditions:**

- **Open questions, owner and next check:**
