CVT4K-S Single-Mode LED Fiber Converter
The NovaStar CVT4K-S extends LED display signal connections through single-mode fiber. Its four LC optical ports support two primary paths and two backups, while 16 Neutrik Gigabit Ethernet ports provide electrical data input or output. This is a fiber converter for the display signal chain; select it according to the sending equipment and optical connection requirements.

Optical-Port Mapping and Backup
OPT1 carries Ethernet ports 1–8, and OPT2 carries ports 9–16. OPT3 backs up OPT1; OPT4 backs up OPT2. The backup optical connections protect the corresponding data paths rather than creating two additional groups of Ethernet channels.
The factory-installed optical modules are hot-pluggable. Use OS1 or OS2 twin-core fiber with LC connectors and the loss limits listed above. Confirm that the optical equipment at the other end matches the required module and signal configuration.
Control Connections and Status Indicators
Use the separate Ethernet control port or USB Type-B port to connect a control computer. On the front panel, green Ethernet indicators show a normal cable connection; flashing yellow indicates data transmission, while steady yellow indicates no data transmission. A steady optical indicator shows a normal fiber connection. PWR is red when power is normal, and STAT flashes green during normal operation.
Frequently Asked Questions
Is CVT4K-S a single-mode or multimode converter?
CVT4K-S is the single-mode model. Its V1.0.2 specification calls for OS1/OS2 twin-core 9/125 μm fiber with LC connectors and a 1310 nm optical module.
What is the specified transmission distance of CVT4K-S?
The original specification lists 10 km for its optical module. The fiber connection must meet the documented insertion-loss and return-loss requirements.
Which Ethernet ports correspond to OPT1 and OPT2?
OPT1 corresponds to Ethernet ports 1–8, while OPT2 corresponds to ports 9–16. OPT3 is the backup for OPT1 and OPT4 is the backup for OPT2.
Does CVT4K-S provide redundant power?
Yes. The specification lists dual redundant power supplies and two power-connector types: a 3-pin socket and PowerCON. Input is 100–240 V AC, 50/60 Hz.
What does a steady yellow Ethernet indicator mean?
A steady yellow Ethernet indicator means there is no data transmission. Flashing yellow indicates data transmission; the separate green indicator reports the cable connection.
