Description
Reliable Gigabit Uplinks for Corporate Networks in Myanmar
The D-Link DEM-311GT is a high-performance, industry-standard 850nm Multi-Mode SFP (Mini-GBIC) optical transceiver module designed to establish stable, lightning-fast Gigabit connectivity. Specifically built for high-speed local data transport, it provides essential signal amplification over multi-mode fiber optic frameworks for distances up to 550 meters. This hot-swappable module is the ideal hardware component for enterprise server closets, campus network backbones, and telecom infrastructures throughout Yangon, Mandalay, and growing commercial hubs across Myanmar.
Key Features & Performance Highlights
- Dedicated Gigabit Ethernet Connectivity: Delivers full-duplex 1000BASE-SX transmission speeds, effectively eliminating bandwidth bottlenecks in demanding switch-to-switch and switch-to-server deployments.
- Universal SFP MSA Compliance: Fully matches Multi-Source Agreement specifications, allowing seamless interoperability and native port configuration with D-Link managed switches and standard network hardware.
- Hot-Swappable Module Structure: Change, remove, or replace the transceiver module directly while the switch system is powered on, eliminating network downtime and ensuring continuous uptime for business platforms.
- Enhanced Metal Housing for Reduced EMI: Features a durable, ruggedized steel casing configuration that dramatically minimizes Electro-Magnetic Interference while expanding hardware service life.
- Laser Eye Safety Certification: Compliant with strict safety standards including Class 1 Laser EN 60825-1, FDA 21, 1040.10, and 1040.11 guidelines for safe commercial network deployments.
