The HGF2001 is suitable for fiber optics Fast Ethernet LAN, FTTx, or xDSL applications. It provides fiber optics bandwidth and link distance advantages to the existing network infrastructures with minimum upgrade expenses. By integrating WDM technology and 802.3ah OAM function into this product line, a single fiber transports both downstream and upstream signals and is easy to manage and diagnose. As a result of efficiently utilizing the fiber?™s bandwidth, cabling, installation and maintenance costs are greatly reduced.
