## Summary description

D-Link DEM-211 is a multi-mode SFP fiber transceiver module supporting 100 Mbit/s data rate and up to 2000 m transmission over 100Base-FX cabling. Plug-in form factor for easy installation in compatible switches or media converters. Certified to RoHS, FDA/CDRH, TUV and UL standards. Suitable for extending Ethernet links over multimode fiber in campus, access or industrial networks.

## Long description

D-Link DEM-211 is a Small Form Factor Pluggable (SFP) fiber transceiver module designed for 100Base-FX multimode fiber links. The module supports a data rate of up to 100 Mbit/s (200 Mbit/s full duplex) and a transmission distance of up to 2000 meters, and fits into compatible switches or media converters for easy installation. The transceiver uses duplex LC connectors and is compliant with SFP MSA and IEEE 802.3u standards, with certifications such as RoHS, FDA/CDRH, TUV and UL.
Advantages
The DEM-211 provides hot-swappable installation, low jitter performance for stable optical links and standardized SFP compatibility for broad device support. Its multimode design and 100Base-FX compliance enable reliable Ethernet extension over fiber without requiring special configuration on supported switches and converters.
Suitable for
Extending Ethernet connections over multimode fiber in campus networks
Linking buildings and access points within an enterprise or industrial site
Integration with media converters and SFP-capable switches for access or distribution layers
Key specifications
Model: D-Link DEM-211
Form factor: SFP (Small Form Factor Pluggable)
Fiber type: Multimode
Standard: 100Base-FX, IEEE 802.3u
Data rate: 100 Mbit/s (200 Mbit/s full duplex)
Maximum transmission distance: up to 2000 m
Connector: duplex LC
Certifications: RoHS, FDA/CDRH, TUV, UL
How to use
Insert the SFP transceiver into an empty SFP slot on a compatible switch or media converter until it clicks into place. Connect multimode fiber cables with duplex LC connectors to the module, observing correct transmit/receive orientation. Configure the connected device as needed for 100Base-FX operation or allow auto-negotiation where supported. The module is hot-swappable, so it can be installed or removed while the host device is powered on following standard handling precautions.
Usage recommendations
Use multimode fiber with appropriate core size and follow connector cleanliness best practices. Verify compatibility with the host device's SFP support list and ensure fiber patching maintains correct polarity to achieve the specified 2000 m range and reliable 100 Mbit/s links.
