1.0 The Doctrine of Chromatic Triage

At Fatmin Labs, the identification of a bitstream must be instantaneous. We utilize a Chromatic Signal Mapping (CSM) protocol to ensure that the function of a conductor can be determined from across the machine room. While the availability of specific pigments in the polymer sheathing may fluctuate due to global supply-chain desynchronization, the following standards are the "The Chromotonic Baseline."

2.0 Primary and Secondary Spectrum Allocation

The facility utilizes a strict color-to-function ratio to prevent the accidental cross-contamination of signal types:

• OBSIDIAN (Black): Reserved for High-Capacity Backups. These cables carry the "memory" of the lab and are considered high-gravity bitstreams.
• CRIMSON (Red): Primary Data Uplinks. These are "hot" lines; they carry the active production load and should not be interfaced without Grade 4 clearance.
• CERULEAN (Blue): Secondary/Redundant Streams. These provide the failover capacity for the primary crimson lines.
• EMERALD (Green): Storage Fabric. Reserved for the movement of data between compute nodes and the block-storage arrays.
• PEWTER (Grey): Console/Management Interconnects. Used for direct serial communication with the internal waneshaft.
• AMBER (Yellow): Out-of-Band (OOB) / LOM. The "Lights Out" management network that operates even when the primary logic boards are in stasis.

3.0 The DAC Complexity & Chromatic Rectification

Direct Attach Copper (DAC) cables present a significant challenge to the CSM protocol, as they are natively manufactured in Obsidian (Black) sheathing. To rectify this, technicians must apply Chromatic Frequency Indicators (Electrical Tape or Paint Pen) at 15cm intervals.

Failure to "tag" a DAC cable leads to Visual Signal Drift, where a technician may mistake a management uplink for a backup stream, leading to catastrophic administrative errors.

4.0 Photonic Fiber Interconnects & Laser Safety

Fiber Optic cabling introduces a variable-spectrum challenge. At Fatmin Labs, we standardize on Aqua for Multi-mode and Yellow for Single-mode.

CRITICAL SAFETY ADVISORY: Under no circumstances should a technician attempt to visually verify the "Signal Heartbeat" by looking directly into a Single-mode fiber optic aperture. The photonic emission is tuned to a frequency that can "burn" the digital image onto the human retina.

• If direct optical exposure occurs:
1. Immediately cease all maintenance.
2. Proceed to the Emergency Eyewash Station.
3. Report to the Duty Nurse for a retinal recalibration and grammeter check.
