Convertitore multimediale Gigabit LevelOne da RJ45 a SFP, PoE PD

The LevelOne GVT-2010 is a Gigabit media converter that converts between 10/100/1000Base-T copper and 1000Base-SX/LX fiber links using an SFP slot for pluggable optic modules. It complies with IEEE 802.3, 802.3u, 802.3z and 802.3ab standards, extends network reach from 100 m over UTP to up to 100 km over fiber, and supports PoE-PD (802.3af/at) so it can draw power from a PoE-PSE switch or mid-span injector.

Advantages

The GVT-2010 provides flexible RJ45-to-SFP connectivity, support for 10/100/1000 Mbps adaptive operation and 9K jumbo frames to improve throughput for large packets. Built-in Link Fault Pass-through (LFP) and IEEE 802.3x flow control help maintain reliable transmission and reduce packet loss. Its compact black housing, LED indicators and compliance with PoE-PD simplify deployment in locations without local power.

Suitable for

• Extending Ethernet networks from copper to single-mode or multi-mode fiber links
• Connecting remote devices where power is supplied via PoE (IP cameras, access points, VoIP phones) using PoE-PSE
• Data center uplinks or campus backbone segments requiring Gigabit fiber connectivity

How to use

Install a compatible SFP transceiver into the SFP slot and connect fiber cable to the transceiver. Connect the Ethernet device to the RJ-45 port with UTP cable. If PoE power is required, connect the RJ-45 port to a PoE-PSE switch or mid-span injector so the GVT-2010 can draw power as a PoE-PD. Verify power and link LEDs for status and ensure transceiver type and fiber type (single- or multi-mode) match the network design. Place the unit in a ventilated location within the specified operating temperature range.

Recommendations

Use SFP modules and fiber cabling that match the link distance and wavelength requirements; verify PoE budget on the PoE-PSE device before connecting powered equipment. Regularly check link LEDs and monitor for link faults to take advantage of LFP functionality.
