Different colored pull rings on the optical module

The color of an optical module pull ring indicates its wavelength, fiber type, and transmission distance, enabling quick identification and proper deployment.

Overview

Optical module pull rings (or pull tabs) are color-coded to help technicians quickly identify the module's wavelength, compatible fiber type, and transmission distance without removing it from the port. This system is widely used for SFP, SFP+, QSFP, BiDi, and CWDM modules, streamlining installation, maintenance, and troubleshooting in data centers and network environments. Common Color CodesSingle-Mode and Multi-Mode ModulesBlack: 850nm, multimode fiber, short-distance transmission (typically
