TP-Link TL-FC311B-2 Gigabit WDM Media Converter
Seamlessly bridge the gap between copper-based Ethernet networks and fiber optic infrastructure with the TP-Link TL-FC311B-2 Gigabit WDM Media Converter. Designed for high-performance commercial deployments—such as park surveillance systems, enterprise office networks, and long-range remote connections—this unmanaged media converter converts high-speed gigabit electrical signals into optical signals (and vice versa) for reliable, long-distance data transmission.
Key Features
- Blazing-Fast Gigabit Conversion: Outfitted with 1× 10/100/1000Mbps Auto-Negotiation RJ45 port (supporting Auto-MDI/MDIX) and 1× Gigabit SC Fiber Port to ensure zero-bottleneck data transfers.
- Cost-Saving WDM Technology: Adopts Wavelength Division Multiplexing (WDM) to transmit and receive data over a single physical strand of fiber. This reduces fiber installation and cabling costs by half compared to dual-strand configurations.
- Extended Network Reach: Converts and extends your standard Ethernet signal up to 2 km over single-mode fiber—far surpassing the 100-meter physical limitation of traditional copper cables.
- Optimized Wavelength Pairing: Transmits data at 1310 nm (TX) and receives data at 1550 nm (RX). Designed to seamlessly pair with the counterpart terminal device TL-FC311A-2 (which transmits at 1550 nm and receives at 1310 nm).
- Flexible & Scalable: Works perfectly as a standalone, compact desktop device or can be easily mounted into TP-Link's TL-FC1420 rackmount chassis for organized, clean server room deployments.
- Plug and Play Simplicity: No software configuration or drivers required. Auto-negotiation of Half-Duplex/Full-Duplex transfer modes delivers instant network integration.
