4port 10/100/1000Base-T Fiber Switch Advantages:A, Built-in energy-saving Green Network technologyB, L2 Manager Fiber Switch for FTTx CPE ApplicationC, Smart Link for Fiber Speed Selection DescriptionThe LS-1O4G Series  Provides three advantages and integration to an stand-alone optical fiber Network Manager switch  for 4 x 10/100/1000Base-T. This Fiber Manager Switch with its idea functions Smart Link ability of selecting either 100Base-FX or 1000Base-X on the fiber port, using the SFP module. With this converter the FTTx networks can grow from today’s need of 100Mbps to tomorrow’s need of 1Gbps – without the need of physically upgrading the converter. Simply exchange the 100 Mbps SFP in the access node switch with a 1Gbps SFP (the access node switch must of course support Gbps speed). The converter will then automatically select the higher speed – and you now have a full featured Gbps network all the way to the end-user.Features * Power Saving Up to 60%.* Layer II feature for IP remote manager meet the FTTx application.* Smart Link converter that supports both  100Mbps and 1Gbps on the fiber port for using SFP module.* Operates in store and forward mode.* MDI/MDIX auto-crossover for TP ports.* Auto-negotiation (10/100/1000 Mb/s) for TP ports.* Maximum packet size: 9216 Bytes.* Support TP port RJ45 Cable Diagnostic function and get Cable Length/Status.
