The NovaStar CVT10-S single-mode fiber converter links an LED sending system and display over optical fiber. It converts between optical and Ethernet signals in either direction, with two optical ports and ten Gigabit Ethernet ports.
CVT10-S specifications
| Item | Specification |
|---|---|
| Model | CVT10-S: single-mode; CVT10-M is the separate multimode version |
| Optical ports | 2; up to 10 Gbit/s each; factory-installed, hot-swappable optical modules |
| Ethernet ports | 10; up to 1 Gbit/s each |
| Single-mode optical link | 1310 nm; up to 10 km; OS1/OS2 twin-core 9/125 μm fiber with LC connectors |
| Optical port roles in CVT mode | OPT1 master; OPT2 backup |
| Control | 1 × USB Type B |
| Power connectors | 3-pin power socket and PowerCON socket, selected by the power switch |
When are all ten Ethernet ports available?
| Signal direction / source | Available Ethernet ports |
|---|---|
| Fiber in, Ethernet out; input device with 8 or 16 Ethernet ports | First 8 ports |
| Fiber in, Ethernet out; input device with 10 or 20 Ethernet ports | All 10, subject to compatible device firmware |
| Ethernet in, fiber out | All 10 |
The original V1.2.2 documentation refers to a future upgrade if ports 9 and 10 are unavailable. Treat that as a version-dependent note, not a guarantee that any installed firmware enables them. Verify the sending device and converter versions for the planned connection.
Installation and control
CVT10 supports horizontal, suspended and rack installation. The documented rack assembly combines two CVT10 units, or one unit with a connecting piece. Use the supplied installation guidance for the rack arrangement.
The USB Type B connection is for program updates through a control computer, not cascading. Although optical modules are hot-swappable, the specification does not permit hot-plugging the PowerCON connector.

CVT10-S FAQ
What is the difference between CVT10-S and CVT10-M?
CVT10-S uses single-mode optics. CVT10-M is the multimode version; choose matching fiber and optical equipment rather than mixing the two link types.
What fiber is specified for CVT10-S?
The linked document specifies OS1/OS2 single-mode twin-core 9/125 μm fiber with LC connectors, using 1310 nm optics for a stated distance up to 10 km.
Why are ports 9 and 10 unavailable?
In fiber-to-Ethernet operation, an 8- or 16-port input device uses the first eight ports. Ten-port operation with a 10- or 20-port source also depends on the supported firmware configuration.
Can CVT10-S convert Ethernet into fiber?
Yes. Ethernet-to-fiber operation is supported, with all ten Ethernet ports available according to the linked specification.
Can the USB port cascade multiple converters?
No. The specification identifies USB Type B as a program-update connection to a control computer, not a cascading port.
