The OMS113 is a Ethernet switch with triple OPTOLOCK™ plastic optical fibre (POF) ports and single RJ45 copper port. It performs as a layer 2 switch with 80 m transmission distance over POF POF cable according IEC 6073-2 Class A4a2 as e.g. Mitsubishi Optohome RHEE4002). 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, 10/100Base-TX and 100Base-FX. The data transmission is realized by switching and store-and-forward technologies, based on IK MAC address table. OMS113 is a RoHS compliant product.
