Cudy Fiber Media Converter Gigabit Side B TX1550nm RX1310nm SM 20Km SC MC100GSB-20B

The Cudy MC100GSB-20B Gigabit Fiber Media Converter converts copper Ethernet signals to single-mode fiber-optic networks, enabling long-distance extensions up to 20 km over a single strand of fiber. Designed as the complementary Side B unit to the MC100GSB-20A, it uses WDM (Wavelength Division Multiplexing) BiDirectional technology to receive on 1310 nm and transmit on 1550 nm. This single-fiber core operation reduces cabling costs by half while maintaining robust Gigabit throughput. Featuring auto-negotiation MDI/MDI-X copper connectivity, full diagnostic LEDs, and a durable metal housing, it offers an efficient plug-and-play solution for expanding enterprise networks, connecting remote surveillance systems, or bridging building-to-building links.

• Long-Distance Gigabit Connectivity: Converts 10/100/1000Base-T copper network signals to 1000Base-BX single-mode fiber for data transmission up to 20 km.
• Single-Fiber WDM BiDi Efficiency: Operates over a single fiber strand (TX 1550 nm / RX 1310 nm) paired with Side A to halve fiber cabling requirements.
• High-Performance Architecture: Features a premium chipset with 2 Mbit buffer memory and 16 KB Jumbo Frame support to ensure smooth, low-latency transmission without packet loss.
• Proactive Fault Diagnostics: Built-in Link Fault Pass Through (LFP) and Far End Fault (FEF) functions instantly detect and signal fiber or copper disruptions to prevent network downtime.
• Durable & Compact Design: Enclosed in a rugged metal casing suitable for desktop placement or installation in standard 19-inch media converter rack chassis.
• Plug and Play Operation: Auto-negotiation for duplex mode and speed on the RJ45 port eliminates complex configuration for fast deployment.
