Planet GS-5220-16S8C 24 Port (24 x SFP + 8 Combo RJ45) L2+ Gigabit Switch

The Planet GS-5220-16S8C is a 24 port Layer 2+ Managed Core Fiber Switch which provides high-density performance and support IPv4 and IPv6 hardware Layer 3 static routing and 24 100/1000Base-X dual-speed SFP slots in a 1U case. With these features, it is able to cross over different VLANs and different IP addresses for the purpose of having a highly-secured, flexible management and long-reach networking application. As a fiber backbone switch, it can flexibly work with suitable SFP transceivers to have a long connection of up to 120km via optic fiber cabling. It is well suited for SMBs, campuses and enterprises for their backbone and workgroup network applications by providing affordability, high performance, long distance and stable transmission quality.

Interface

The GS-5220-16S8C SFP slots support dual-speed, 1000Base-SX / LX or 100Base-FX fiber transceivers; the distance can be extended from 550 meters to 2 kilometers (multi-mode fiber) and up to 10/20/30/40/50/70/120 kilometers (single-mode fiber or WDM fiber). It also supports SFP-DDM (Digital Diagnostic Monitor) function that greatly helps network administrator to easily monitor real-time parameters of the SFP, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.
