Product Description
The D-Link DEM-211 is a 100Mb/s SFP (Small Form-factor Pluggable) transceiver module designed for Fast Ethernet (100BASE-FX) applications. This module operates at a wavelength of 1310nm, which is standard for longer-reach connections over Single-Mode Fiber (SMF). It enables network devices to connect via fiber optic cabling, supporting distances of up to 2 kilometers, making it suitable for campus backbones, metropolitan area networks, or inter-building links. This SFP module features duplex LC connectors, providing a secure and reliable connection for the single-mode fiber optic cable. The 1310nm wavelength is well-suited for SMF, which offers lower signal attenuation and dispersion compared to multi-mode fiber, allowing for extended transmission distances. The 100Mb/s data rate is appropriate for legacy Fast Ethernet infrastructure or specific applications that do not require higher bandwidths. The DEM-211 is hot-pluggable, meaning it can be inserted or removed from network equipment without interrupting network operations, facilitating easy installation and maintenance. D-Link's DEM-211 provides a reliable and efficient solution for extending network connectivity over significant distances using single-mode fiber, ensuring robust communication for various enterprise and service provider environments.
