Key Features of LINK-PP LS-MM858G-S3I 8G SFP+
LINK-PP LS-MM858G-S3I is an industrial-grade 8G Fibre Channel transceiver engineered for robust data links in demanding network environments. Equipped with a duplex LC interface and 300m transmission capability, it enables stable storage network interconnections across wide industrial operating temperatures.
LINK-PP LS-MM858G-S3I 8G SFP+ Optical Module
The hot-pluggable SFP+ footprint allows network technicians to install or replace modules without interrupting host system power. Full compliance with the SFP+ MSA guarantees straightforward mechanical fit and broad hardware interoperability across multi-vendor platforms.
LS-MM858G-S3I: 8 Gbps Connectivity for Industrial Storage Networks
Operating at line rates up to 8.5Gbps, this SFP+ module ensures smooth, low-latency traffic flow across demanding storage area networks. Such transmission speeds reliably support mission-critical SAN arrays, local industrial storage enclosures, and automated enterprise backup servers.
LS-MM858G-S3I Module with 850nm Wavelength
An internal 850nm VCSEL transmitter provides the precise optical emission profile required for short-range signaling. This designated spectral band works hand-in-hand with multi-mode fiber cores to achieve optimal signal integrity while keeping power consumption low.
LS-MM858G-S3I Module Supporting 300m Transmission
Link distances of up to 300m over OM3 multi-mode fiber accommodate extended cabling pathways across equipment rooms. Such physical reach easily connects distributed server clusters and storage cabinets across large factory floors or multi-floor enterprise buildings.
