Flexible and Extendable Solution
The 2 mini-GBIC SFP slots built in the GS-5220-8P2T2S 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 10/20/40/60/80/120 kilometers (single-mode fiber or WDM fiber). They are well
suited for applications within the enterprise data centers and distributions.
Intelligent SFP Diagnosis Mechanism
The GS-5220-8P2T2S supports SFP-DDM (Digital Diagnostic Monitor) function that greatly helps network administrator to
easily monitor real-time parameters of the SFP transceivers, such as optical output power, optical input power, temperature,
laser bias current, and transceiver supply voltage.
