What is CodingBox

CodingBox is a universal toolkit for reading, diagnosing and coding optical transceivers (SFP, SFP+, QSFP and other form factors) in one place. It combines a browser application, a hardware driver and programmer boards, backed by a database of firmware and vendor passwords.

The three parts

CodingBox is made of three pieces that work together:

Online application — runs in your browser. Reads module memory, shows Digital

Diagnostic Monitoring (DDM), lets you edit EEPROM pages and look up codes.

Driver — a small program on your computer that connects the web application to

a programmer board over USB. Without it the app runs in simulator mode.

Programmer — the board that physically holds the transceiver and talks to its

memory.

New here? You can try the interface right now in the live demo — it opens in simulator mode, no hardware required.
