Convertitore media LevelOne RJ45 a SC Gigabit, fibra singlemode, 20 km

The LevelOne GVT-2002 is a Gigabit media converter that converts 10/100/1000Base-T copper Ethernet (RJ45) to single‑mode SC fiber, enabling network extension up to 20 km. It supports auto‑sensing for 10/100/1000Base‑T, full and half duplex operation, and can be used as a standalone unit or mounted as a slide‑in module in the CHV‑2000 19” converter rack.

Advantages

The converter supports 9K jumbo frames and extra‑long packets up to 1.6 KB to improve throughput for large frames. Built‑in LFP (Link Fault Pass‑through) with Smart LFP modes allows monitoring and coordinated fault handling between the fiber and copper ports. IEEE 802.3x flow control reduces packet loss for reliable transmission. Dip switches provide simple local configuration, and the unit operates across a wide temperature range from -10 °C to 55 °C.

Suitable for

• Extending Ethernet networks over long distances using single‑mode fiber (up to 20 km)
• Connecting copper Gigabit switches or servers to fiber backbones
• Integration into central wiring closets using the CHV‑2000 19” rack

How to use

Connect the RJ45 port to a copper Ethernet device (switch, router or server) and the SC port to the single‑mode fiber cable. Ensure auto‑negotiation settings match the connected devices or manually configure speed/duplex if required. Use the dip switches to select the desired LFP mode (cut‑through, pass‑through, or smart) and other local settings. Power the unit with a 5 V DC, 2 A adapter and mount it as a standalone device or slide it into the CHV‑2000 rack for centralised installation.

Recommendations

Use single‑mode SC fiber and quality connectors for distances up to 20 km. Verify fiber polarity and test link integrity after installation. If multiple converters are used in a rack, manage power and cooling to maintain the operating temperature range.
