Description
The Perle S-1110DP-S2ST120 is a feature-rich Gigabit Ethernet Stand-Alone Media Converter with PoE Power Sourcing capability, designed to extend networks over long distances while powering connected devices. It transparently converts copper Ethernet to fiber, connecting dual 10/100/1000BASE-T (RJ-45) ports over UTP to 1000BASE-ZX 1550 nm single-mode fiber (ST) at distances up to 120 km (74.6 miles).
As a Power Sourcing Equipment (PSE) device, it supplies IEEE 802.3af PoE (15.4W) and IEEE 802.3at PoE+ (30W) to standards-based powered devices, such as IP cameras, VoIP phones, access points, and conferencing systems. Advanced features like Auto-MDIX, Smart Link Pass-Through, Fiber Fault Alert, and Remote PD Reset reduce downtime and simplify troubleshooting, making it an ideal solution for enterprise networks, surveillance, and industrial deployments.
Backed by Perle’s lifetime warranty and worldwide technical support, this converter provides reliable fiber extension and flexible PoE deployment in one compact device.
