Product Description

The X20HB2881 Hub Expansion Module is an integral component for expanding network capabilities within the X20 series infrastructure. It is a reliable product of B&R which is a widely known company for its advanced technology and integrated industrial automation products which are used across various industries.

This module enables two 100BASE-FX hub connections via female duplex LC connectors by supporting multimode fibre with core diameters of 62.5/125 um or 50/125 um. It ensures a stable data transfer rate of 100 Mbit/s in half-duplex mode, with a propagation delay between 0.96 to 1 us. Operating within the 1270 to 1380 nm wavelength range, it is well-suited for standard optical fibre systems. The X20HB2881 power link is engineered to uphold electrical isolation between the power supply and Ethernet interfaces by ensuring reliable performance in both horizontal and vertical mountings. It supports segment lengths up to 175 meters in half-duplex mode and extends to 2 kilometers in POWERLINK mode which helps in making it versatile for various industrial network configurations. Regarding environmental durability, it functions dependably within a temperature range of -25 to 55 degrees C contingent on the hub setup and orientation. The module meets IP20 protection standards by making it useful for installations in regulated environments.

The X20HB2881 unit maintains operational consistency at elevations up to 2000 meters without significant performance loss with only a slight temperature de-rating required above this altitude. This helps to increase its usefulness. The X20HB2881 power link X20 series substantial optical power budget, ranging from 7.5 dB to 11 dB depending on the fibre type enhances its effectiveness over long distances. Coupled with its compliance with strict operational and storage humidity conditions, this hub expansion module offers a dependable solution for networking applications.
