In standard IT environments, a USB cable is just a data pipe. But in critical environments like medical imaging suites (MRI/CT), semiconductor manufacturing floors, or precision metrology labs, a copper USB cable is a liability.
It acts as an antenna for electromagnetic interference (EMI). It creates dangerous ground loops between equipment on different power phases. It is a conductive path for high-voltage surges that can destroy sensitive instruments.
For standard long-distance needs, hybrid AOCs are great. But for environments requiring absolute signal integrity and safety, the only solution is the USB 3.0 AM to AF Y-Cable Power Supply Pure Fiber Active Optical Extension Cable.
The "Pure Fiber" Revolution: Achieving Galvanic Isolation
What differentiates this cable from 95% of AOCs on the market is what's missing: Copper inside the cable run.
Standard "Hybrid" AOCs use fiber for data and copper wires alongside them for power. Our Pure Fiber technology transmits ALL data via light pulses over multimode optical fiber over long distances (up to 100m+).
This achieves true Galvanic Isolation:
· Physical Break: There is no electrical conductivity between the host PC and the remote device. Electrons cannot cross the gap.
· EMI/RFI Immunity: You could run this cable right next to a high-voltage generator or inside an MRI bore, and the data signal will remain pristine. Light is unaffected by magnetic fields.
· Ground Loop Elimination: By severing the electrical ground path between the source and destination, you permanently eliminate hum, noise bars in video, and data errors caused by ground potential differences.
If electricity can't travel down the cable, why is there a USB Y-Cable at the source end?
Reliability starts at the source. Converting 5Gbps electrical signals into light requires precise, stable power for the laser transmitter chipset. Standard USB ports on laptops or industrial PCs often fluctuate in voltage.
The Y-Cable Power Supply design plugs into two host ports to guarantee a clean, robust power supply specifically for the transmitting optical engine. This ensures that the light pulses sent down the pure fiber path are powerful and stable, preventing data packet loss at the very start of the chain.
(Note for Integrators: Since no power reaches the remote end, your remote device must be self-powered or use a local power supply plugged into the female extension hub.)
Inside an MRI room, ferrous metals and conductive wires are prohibited due to intense magnetic fields. Our Pure Fiber cable is non-magnetic and non-conductive, making it the safest choice for connecting in-room control surfaces to external workstations.
In environments with heavy motors, welders, and drives, electrical noise destroys USB signals on copper wire. Pure Fiber is impervious to this factory floor noise. Furthermore, its extreme flexibility and lighter weight make it ideal for routing through robotic arms without mechanical fatigue.
In sensitive audio recording or laboratory measurement, ground loops create audible hum or measurement errors. Pure Fiber provides the ultimate "ground lift," ensuring the recorded data is exactly what the sensor captured, without interference from the PC's power supply.
When electrical safety, noise immunity, and data integrity are non-negotiable, you cannot rely on copper. You need a physical barrier.
