GS-5220-16T4S2X/GS-5220-16T4S2XR
Flexible and Extendable Solution
The 4 mini-GBIC SFP slots built in the GS-5220-16T4S2X and GS-5220-16T4S2XR support dual speed as it features 100BASE-FX and 1000BASE-SX/
LX SFP (Small Form-factor Pluggable) fiber-optic modules. Now the administrator can flexibly choose the suitable SFP transceiver according to not only
the transmission distance, but also the transmission speed required. The distance can be extended from 550 meters to 2km (multi-mode fiber) and up to
10/20/30/40/50/70/120kilometers(single-modeberorWDMber).Theyarewellsuitedforapplicationswithintheenterprisedatacentersanddistributions.
Intelligent SFP Diagnosis Mechanism
The GS-5220-16T4S2X and GS-5220-16T4S2XR support SFP-DDM (Digital Diagnostic Monitor) function that greatly helps network administrator to easily
monitor real-time parameters of the SFP and SFP+ transceivers, such as optical output power, optical input power, temperature, laser bias current, and
transceiver supply voltage.
