Key Features of LINK-PP LS-MM311G-02AI 1G SFP
LINK-PP LS-MM311G-02AI is an industrial-grade optical transceiver designed to deliver stable 1Gbps data links over multimode fiber. It combines a 1310nm operating wavelength, 2km reach, standard duplex LC interface, and integrated digital diagnostic monitoring into a rugged, hot-pluggable form factor.
LINK-PP LS-MM311G-02AI 1G SFP Optical Module
This transceiver utilizes a hot-pluggable footprint that allows seamless installation and replacement without powering down host equipment. Full compliance with SFP MSA standards ensures broad hardware compatibility across multi-vendor networking switches and routers.
LS-MM311G-02AI: 1 Gbps Connectivity for Outdoor Surveillance Links
Gigabit Ethernet throughput ensures uninterrupted and low-latency bandwidth for continuous high-definition video streaming. Such reliable 1Gbps transmission makes it well-suited for remote outdoor surveillance cameras and perimeter monitoring networks.
LS-MM311G-02AI Module with 1310nm Wavelength
An integrated 1310nm FP laser transmitter provides an optimal balance between optical signal strength and fiber attenuation. Operating in the 1310nm optical window allows multi-mode systems to achieve greater link stability than standard 850nm alternatives.
