NovaStar CVT10-S Single-Mode LED Fiber Converter
The CVT10-S transports LED display data between compatible sending equipment and the screen over fiber. It supports conversion in either direction: optical input to Ethernet output, or Ethernet input to optical output. It is the single-mode version of the CVT10 family.
The two optical ports are not two independent groups of ten Ethernet outputs. In CVT mode, OPT1 is the primary port and OPT2 is the backup. The parameters below follow the original CVT10 Specifications V1.2.2, dated May 31, 2021.
| Parameter | Specification |
|---|---|
| Optical ports | 2 × 10G ports with factory-installed, hot-swappable optical modules |
| Ethernet ports | 10 × Gigabit Ethernet, each up to 1 Gbit/s; usable port count depends on direction and connected equipment |
| Optical module data rate | 9.95–11.3 Gbit/s |
| Wavelength / specified distance | 1310 nm; 10 km with the documented CVT10-S optical arrangement |
| Fiber type | OS1/OS2, single-mode twin-core, 9/125 μm |
| Fiber connector / loss limits | LC; insertion loss ≤0.3 dB; return loss ≥45 dB |
| Working mode | CVT mode: OPT1 primary and OPT2 backup; DIS is reserved in this revision |
| USB control | USB Type B for program upgrades using NovaLCT V5.4.0 or later; not for cascading |
| Power input | 100–240 V AC, 50/60 Hz, 0.6 A; 3-pin socket or PowerCON selected by the power switch |
| Rated consumption | 22 W |
| Operating conditions | −20°C to +55°C; 10–80% RH, non-condensing |
| Dimensions / net weight | 254.3 × 50.6 × 290.0 mm; 2.1 kg |
When Are All Ten Ethernet Ports Available?
For fiber input and Ethernet output, a sending device with 8 or 16 Ethernet ports makes the first eight CVT10 ports available. A device with 10 or 20 ports supports all ten. V1.2.2 notes that unavailable ports 9 and 10 may depend on a future upgrade; confirm the installed firmware and sender compatibility rather than assuming that an update is already available.
For Ethernet input and fiber output, all ten Ethernet ports are available according to the same specification. Match the sender’s signal mapping and the optical link at both ends before allocating ports.
CVT10-S and CVT10-M Selection
CVT10-S is specified for 1310 nm single-mode fiber and 10 km transmission. CVT10-M is the separate multi-mode model, specified at 850 nm and 300 m using OM3/OM4 twin-core fiber. The model, optical modules and fiber must match the required installation.
Horizontal, suspended and rack installation arrangements are documented. Two units, or one unit plus the connecting piece, can form a rack assembly. Follow the mounting guide and do not hot-plug the PowerCON connector; optical-module hot swapping does not make the power connector hot-pluggable.
Frequently Asked Questions
What fiber cable does the NovaStar CVT10-S use?
The linked specification calls for OS1/OS2 single-mode twin-core fiber, 9/125 μm, with LC connectors. It lists insertion loss no greater than 0.3 dB and return loss at least 45 dB.
How far can CVT10-S transmit?
The specified CVT10-S optical modules use 1310 nm and are rated for 10 km. Match the modules, fiber type and connection quality to the documented configuration.
Why are Ethernet ports 9 and 10 unavailable?
In fiber-in/Ethernet-out operation, a sender with 8 or 16 Ethernet ports uses only the first eight converter ports. Ten-port operation depends on compatible 10-/20-port sending equipment and the applicable firmware. The older PDF contains a future-upgrade note, not proof that every installed unit already supports it.
Are OPT1 and OPT2 independent outputs?
In the documented CVT mode, OPT1 is the primary optical port and OPT2 is the backup. DIS mode is reserved in V1.2.2.
How does CVT10-S differ from CVT10-M?
CVT10-S is the single-mode version with a specified 1310 nm, 10 km optical link. CVT10-M uses 850 nm multi-mode optics with a specified 300 m link. Select the matching converter, modules and fiber.
