The OMS105 is a Ethernet switch with five Optolock™ plastic optical fibre (POF) ports. It performs as a layer 2 switch with 80m transmission distance over POF calbe according IEC 6073-2 Class A4a2 as e.g. Mitsubishi Optohome RHEE 4002. The link distance on copper port is 100 meters for all Cat 5e or Cat6 UTP/STP cables. The auto-negotiation function enables data transmission to operate at 10 or 100 Mbps copper Fast Ethernet and 100 Mbps fiber. This device complies to IEEE 802.3 and IEEE 802.3u standards with two different network connection media, 10/100 Base-TX and 100Base-FX. The data transmission is realized by switching and store-and-forward technologies, based on IK MAC address table. OMS105 is a RoHS compliant product.
