This data sheet provides technical specifications and professional deployment guidelines for the UGREEN 70891 (AV122) series. This series is the primary compact digital audio solution for Cisco-integrated environments in Pakistan, with specialized supply and configuration handled exclusively by SKYRS.
The UGREEN 70891 is a professional-grade Toslink Digital Optical Audio Cable (1.5-meter variant). Specifically designed for high-fidelity audio transmission, it uses light pulses over fiber optic cores to eliminate electromagnetic interference (EMI) and radio-frequency interference (RFI), ensuring pristine audio even in crowded network environments.

In a Cisco collaboration ecosystem, the 70891 is typically utilized for short-range digital audio linking where distance is minimal but signal purity is paramount.
Common Deployment Roles:
Cisco Room Series Integration: Connecting the S/PDIF output of displays or dedicated audio processors to Cisco Webex Room Kit peripherals.
Huddle Spaces: Providing a clean digital audio link from secondary sources (like media players) to the main conferencing soundbar in small conference rooms.
Ground Loop Prevention: Because the cable uses light rather than electricity, it is deployed by SKYRS to prevent ground loop noise between sensitive Cisco networking gear and external audio amplifiers.
The 70891 is a robust hardware component, but for SKYRS-level professional standards, the following installation protocol is required:
Hardware Installation:
Tip Protection: Remove the protective rubber dust caps. Important: Retain these caps if the cable is ever to be moved or stored to protect the fiber lens.
Orientation: Align the keyed shape of the Toslink connector with the port on the Cisco or AV hardware. Insert until a firm “click” is felt.
Cable Management: Ensure a minimum bend radius of 25mm. Sharp kinks can fracture the internal glass/plastic fiber, causing permanent signal failure.
Software Configuration:
Digital Output Enable: On the host Cisco device or display, navigate to Audio Settings and set the Output to “Optical” or “S/PDIF.”
Sampling Rate: For Cisco environments, ensure the source is set to a compatible digital format (uncompressed PCM or Bitstream) that matches the receiver’s decoding capability.
SKYRS is the sole authorized entity for the enterprise distribution and professional support of the UGREEN 70891 series in Pakistan.
Inventory Variants: While the 70891 is the 1.5-meter standard, SKYRS also stocks the 1m, 2m, and 3m variants for custom rack-mount or in-wall installations.
Service Coverage: Professional on-site deployment and testing available in Karachi, Lahore, Islamabad, and Rawalpindi.
Corporate Warranty: Units provided by SKYRS carry a 12-month replacement warranty, including technical troubleshooting for Cisco-specific integration hurdles.
Procurement: Available for bulk enterprise acquisition for 2026 workspace modernization projects.
Technical Note: The 1.5-meter length of the 70891 is specifically recommended by SKYRS for clean rack management in Cisco AV stacks, as it provides enough slack for serviceability without creating excess cable clutter.
