The 2891081 is a small form-factor plug-in (SFP) media module designed to add a fiber optic port to compatible Factoryline devices. It facilitates Ethernet communication over multi-mode fiberglass at a transmission speed of 100 Mbps. The module operates at a wavelength of 1310 nm and supports a typical transmission length of up to 2 km through its single LC multi-mode port. Engineered for reliability in demanding conditions, it functions across an ambient temperature range of -40 °C to 85 °C. This hot-pluggable module is ideal for establishing robust network structures compliant with standards like IEC 61850 in industrial environments.
