NovaStar CVT8-5GS 40G Fiber Converter Overview
The NovaStar CVT8-5GS is a single-mode fiber converter for long-distance LED display data transmission. It converts optical and electrical signals between a compatible sending controller and the LED display system, providing full-duplex transmission with strong resistance to interference. A 40 Gbit/s optical link is converted into eight independent 5G BaseT Ethernet connections.
The CVT8-5GS is designed for fixed installations, touring systems, control rooms and other projects where copper cable distance or electrical interference makes a fiber link the better choice. Its supplied optical module is hot-swappable, and the single-mode connection supports transmission distances of up to 10 km.
Key Features
- Single-mode fiber transmission up to 10 km using OS1 or OS2 twin-core fiber
- One 40 Gbit/s optical port with a supplied hot-swappable optical module
- Eight 5G BaseT Ethernet ports, each supporting bandwidth up to 5 Gbit/s
- 1310 nm wavelength with LC fiber connectors
- USB Type-B control port for firmware upgrades through NovaLCT V5.4.0 or later; the USB port is not used for cascading
- Front-panel indicators for power, device status, optical connection and Ethernet links
- Horizontal, suspended or 19-inch rack installation options

Installation and Package Contents
The practical chassis can be installed horizontally, suspended or mounted in a rack. Two CVT8-5G units can be combined into one 1U-wide assembly. A single unit can also be paired with the supplied connecting piece for rack installation.
The standard package includes one power cord, one USB cable, two 40G optical modules (including one for the controller), supporting brackets, one connecting piece, mounting screws, an assembly diagram and a certificate of approval.
CVT8-5GS vs CVT8-5GM
Choose the CVT8-5GS for single-mode fiber links up to 10 km. The NovaStar CVT8-5GM is the multi-mode version: it uses 850 nm optics and supports up to 100 m with OM3 fiber or 150 m with OM4 fiber. Both models provide one 40G optical port and eight 5G BaseT Ethernet ports.
Frequently Asked Questions
What does the NovaStar CVT8-5GS do?
It converts a 40G optical link into eight 5G BaseT Ethernet links, allowing LED display data to travel over single-mode fiber between compatible control equipment and the display system.
How far can the CVT8-5GS transmit data?
The supplied 1310 nm single-mode optical module supports transmission distances up to 10 km when the specified OS1 or OS2 twin-core fiber and LC connectors are used.
Can the CVT8-5GS be rack mounted?
Yes. The unit supports rack installation as well as horizontal and suspended installation. Two units, or one unit plus the supplied connecting piece, can form a 1U-wide assembly.
Is the USB port used for signal cascading?
No. The USB Type-B port connects to a computer running NovaLCT V5.4.0 or later for program upgrades; it is not intended for cascading.
