D-Link DEM-211 SFP 100BASE-FX Multi-Mode Fast Ethernet Optical Transceiver

Basic Parameter Table

Core Product Features

1. Entry-level D-Link 100M fast Ethernet multi-mode SFP optical module, compatible with all D-Link switches with SFP slots supporting 100M fiber.
2. Adopts 1310nm laser, stable 2km transmission over standard multi-mode fiber, LC duplex bidirectional design for separate transmit & receive.
3. Hot-swappable plug-and-play design, no need to power off the switch during replacement, convenient for indoor building monitoring and office network maintenance.
4. Ultra-low power consumption, strong anti-electromagnetic interference, supports 24/7 continuous long-term operation for security camera uplink and intranet interconnection.
5. Cost-effective short-distance multi-mode fiber access solution, ideal for small campus, factory workshop internal monitoring networking.

Typical Application Scenarios

1. Short-distance 100M fiber interconnection within 2km multi-mode fiber: office inter-floor, community/factory IP camera centralized backhaul, small park equipment uplink.
2. Small branch store, industrial control equipment fast Ethernet fiber uplink, short-distance monitoring private line access.
3. Not applicable for single-mode fiber long-distance transmission and gigabit/10G high-speed network scenarios.
