Select the CVT8-5GS or CVT8-5GM version to match the optical module, cable and required distance.
CVT8-5GS vs CVT8-5GM
| Parameter | CVT8-5GS | CVT8-5GM |
|---|---|---|
| Mode | Single-mode | Multimode |
| Specified transmission distance | 10 km | 100 m |
| Optical wavelength | 1310 nm | 850 nm |
| Fiber type | OS1 / OS2, twin-core | OM3, 8-core |
| Fiber diameter | 9/125 μm | 50/125 μm |
| Connector | LC | MPO |
| Insertion loss | ≤0.3 dB | ≤0.1 dB |
| Return loss | ≥45 dB | ≥50 dB |
| Optical module | 40 Gbit/s, hot-swappable | 40 Gbit/s, hot-swappable |
These are the model-specific values in NovaStar’s V1.0.0 specification dated July 10, 2022. A single-mode LC cable and a multimode MPO cable are not interchangeable; match the complete optical connection at both ends.

USB Control and Connection Indicators
The USB Type-B port connects to a control computer running NovaLCT V5.4.0 or later for program upgrades. It is not a cascading port. The PWR indicator stays on with normal power, STAT flashes during normal operation, and OPT1 stays on when the fiber connection is normal. Ethernet indicators identify cable connection and data activity.
Installation and Optical Modules
The converter supports horizontal, suspended and rack installation. The original assembly diagram shows two converters, or one converter with a connecting piece, combined for installation in a standard 19-inch rack. Follow that diagram and the mounting requirements in the PDF.
The specification lists two 40G optical modules in the accessory set, including one for the controller. Confirm that the supplied model and modules match the planned connection. The optical module is hot-swappable; the PowerCON power connector must not be connected while live.
Frequently Asked Questions
What is the difference between CVT8-5GS and CVT8-5GM?
CVT8-5GS is the 1310 nm single-mode version specified for 10 km with OS1/OS2 twin-core LC fiber. CVT8-5GM is the 850 nm multimode version specified for 100 m with OM3 8-core MPO fiber.
How many Ethernet ports does CVT8-5G have?
It has eight 5G BaseT Ethernet ports, each supporting bandwidth up to 5 Gbit/s, plus one optical port supporting up to 40 Gbit/s.
Can I use USB to cascade CVT8-5G converters?
No. The USB Type-B port is for program upgrades from a control computer running NovaLCT V5.4.0 or later. The specification explicitly excludes USB cascading.
Are optical modules included in the specification’s accessory list?
Yes. V1.0.0 lists two 40G optical modules, with one intended for the controller. Verify the supplied model and optical-module configuration before ordering.
Can the optical module and power connector both be hot-plugged?
No. The optical module is documented as hot-swappable, but the PowerCON power connector must not be plugged in while live. Follow the installation instructions in the original PDF.
