This device provides conversion from a Multi-Mode (1000Base-SX) or Single Mode(1000Base-LX) Link to a single-mode(1000Base-LX) link allowing its extension of upto 80km. As many of the GBE switches or NICscome with SX ports, combining such with theGSM1000 provides the most flexible and costeffective way to extend their reach over fibre. The GSM1000 is based on a full digitaltechnology: analog signals from one port areconverted to digital electrical signals, fully retimedthen converted again to the second F/O port.This design provides a reliable and steadyconversion , advanced control/diagnostic featuresand Management. In addition it allows cascadingof several devices, reaching distances of hundredsof km. FibroLAN's unique Link SegmentationTest (LST) allows easy link segmentation(selective per port) to facilitate networkdiagnostics and overcomes the fault propagationwhich is inherent to GBE F/O links. A Loop-Backfunction on each F/O port simplifiestroubleshooting of link problems. Each portprovides separate Link and Activity indicationsfor enhanced diagnostics. The GSM1000 is alsoavailable in SNMP managed versions. Alternatively, GSM1000/MA models may be fullymanaged remotely via a MetroStar system. Thedevice is housed in a robust metal case suitablefor desktop, rack-shelf or wall-mount installation.It features an internal, wide-range, quality powersupply for trouble free installation and reliableoperation. DC powered versions (-48VDC) areavailable. The ETR (Extended Temperature Range)option allows deployment in non-officeenvironments. |
