This module provides conversion from a copper GBE interface (1000Base-T) to a Multi-Mode (1000Base-SX)or Single Mode Link (1000Base-LX) to allow extension of up to 80km. As most of the low cost GBE switchescome with multiple RJ-45 ports, combining such with a MetroStar loaded with MCM1000T modulesprovides the most flexible and cost effective way to extend their reach over fibre. The MCM1000T isbased on a full digital technology: Analog signals from the copper port are converted to digital electricalsignals, fully retimed then converted again to F/O transmitted from the second port. This design providesa resilient and steady conversion , advanced control /diagnostic features and Management. It negotiatedduplex mode at both ports but it may be forced (to FDX) by means of a DIP switch or management. Selective Fault Propagation from the copper port to the F/O port allows end-to-end link integrityverification. A Loop-Back function (F/O port) simplifies troubleshooting of link problems. Each portprovides separate Link and Activity indications for enhanced diagnostics. Like other MetroStar modules,the MCM is fully SNMP managed. All MetroStar modules are hot swappable and equipped with two selfclinchingscrews for easy and safe module insertion and removal. A special LED indicates that the moduleis well inserted in its slot and "alive" even before links are connected. |
