ELS Replacement Procedure for Q3450-LD Systems

84626b59-78d2-459c-8e61-497360cb49df.png

Introduction

This document describes the guidelines for inspection, cleaning, and replacement of the External Laser Source (ELS) modules and ELSFP connectors during debug or replacement procedures for the Q3450-LD systems.

Note: As shown in the illustration above, in the Quigon tool, only one optical ferrule is functional.

  • The recommended process for ELS replacement is: inspection --> cleaning if necessary --> inspecting again to ensure cleanliness --> repeating if needed (2-3 time). If the process fails, use another ELS unit. 

  • If the inspection tools are not available, clean both sides of the optical connectors.
