To modernize the survey multiplexor, Zupt built the ‘Mux Lite.’ Zupt’s Mux Lite is simply a compact network switch with serial and analog ports. Unlike conventional subsea multiplexers, this Mux Lite offers a simplified solution for scenarios where only a limited number of ports are required, making it a cost-effective and space-efficient choice. The user-friendly web interface eliminates the need for complex topside units; only a computer and 10GB ethernet switch on the surface vessel are needed for topside data communication.

As a subsea multiplexor, the Mux Lite provides reliable fiber optic data transfer through a single cable from subsea sensors to the surface. It also has an additional fiber port on the top end cap of the subsea unit, allowing it to be daisy-chained with other units to expand capabilities subsea.

• Low weight
• Web controlled
• 10GB fiber connection
• 4 x 1GB ethernet connectors
• Redundant fiber ports
• Can be daisy-chained
• Configurable power options
• E-fuse protected outputs
• Option for low latency IP cameras

Compact, Rugged, and Built for Offshore Success

Built for the demands of offshore operations, the Zupt Mux Lite delivers seamless data management in a compact, lightweight, and rugged design. This all-in-one fiber multiplexer is optimized for both renewables and traditional offshore projects, where space, speed, and reliability matter most.

Solving Real Offshore Challenges

When a client needed an expandable multiplexer system for a complex renewables project that required multiple sensors and high-powered lights, MUX Lite delivered. Its scalable design and intelligent system architecture make it a powerful solution for dynamic offshore campaigns.

Daisy-Chainable Design

• Dual fiber ports allow multiple Mux Lites to be daisy-chained into a single system
• Enables system expansion without sacrificing performance

Built-in Redundancy

• Ring topology ensures that if one Mux goes down, the remaining systems remains intact
• Closed-loop architecture enhances fault tolerance in critical operations

High Power, High Capability

• AC power input for flexible deployment
• Supports high-power light switching and sensor integration

High-Bandwidth Uplink

• 10 GB uplink supports high-resolution imaging and data-intensive operations
• Ideal for real-time subsea monitoring and positioning

Built for Offshore Survey Use

• Single-mode fiber telemetry for stable, high-speed data transmission over long distances
• Titanium housing that is compact, lightweight, and corrosion-resistant
• Plug-and-play integration with a wide range of survey and positioning sensors
• Remote monitoring ready for both attended and remote operations

With its quick setup and small footprint, Mux Lite is ideal for installations where ROV space is limited. It enables teams to stay agile without compromising the precision and data fidelity that offshore operations demand.

Real-World Proven

Mux Lite is already being deployed globally to support subsea positioning and monitoring, especially in the fast-paced world of offshore renewables. Whether part of a large integrated template or used for standalone interfacing on an ROV, it consistently delivers reliable performance in a small package.
