Extreme 4050-00018 Networks 10Mb/s XENPAK 300m 850nm MMF Transceiver

Product Description

The Extreme Networks 4050-00018 is a XENPAK transceiver module, a larger form factor optical module primarily used in older generations of high-end network switches and routers. This specific module is designed for 10 Megabit Ethernet (10Mb/s) connections and utilizes multi-mode fiber optic cabling. It operates at an 850nm wavelength, which is typical for short-reach multi-mode fiber applications, allowing for data transmission over distances of up to 300 meters. The XENPAK form factor predates smaller modules like SFP and XFP and was common in high-density, high-port-count switches requiring robust thermal management and power delivery. The 4050-00018 module would typically feature SC duplex connectors, a standard for fiber optic connections in that era, providing a secure physical interface for the multi-mode fiber patch cords. This transceiver is intended for environments that still utilize legacy networking equipment supporting the XENPAK interface for 10Mb/s Ethernet connectivity. While 10Mb/s is a very low speed by modern standards, such modules might be found in specialized industrial control systems, legacy network segments, or specific application-specific hardware where this interface and speed are still required. Its primary function is to convert electrical signals from the network device into optical signals for transmission over fiber, and vice versa.
