The AMN6300, Hitachi's 40 Gbit/s extender system, transmits 40 Gbit/s user interface optical signals for a distance of up to 80 km, making it an excellent choice for ultra-high capacity metro-access area networks and enterprise networks.
As an all-in-one system that includes an optical amplifier and a pluggable dispersion compensator required for 80 km transmission, the AMN6300 enables an ultra-high capacity network to be constructed between the user's premises in a metro-access area and the central office of a carrier. In addition, the AMN6300's remote monitoring function allows the AMN6300 to obtain alarm and performance information from a far end AMN6300.
Although the transmission distance between conventional 40 Gbit/s routers is limited to 2 km, the AMN6300 extends that distance to up to 80 km with a built-in optical amplifier and pluggable dispersion compensator. The increased transmission distance translates into lower equipment and operating costs, enabling an efficient network to be constructed at low cost. In addition, high-quality transmission performance does not suffer because the AMN6300's enhanced forward error correction (E-FEC) function maintains a permissible transmission loss of 28 dB or less.
In a network configured only with routers, the isolation of line faults is usually time-consuming and difficult, but with the AMN6300, the process becomes simpler and quicker. The reason is the AMN6300's remote control feature that uses such standard protocols as Telnet and SNMP coupled with a function for monitoring the state of a far end node and a loopback test function. The remote monitoring function uses the OTN frame overhead of the 40 Gbit/s main signal to remotely monitor the alarm and performance information of the far end node in order to obtain optical-level monitoring information and fault occurrence information. On the other hand, the 40 Gbit/s main signal loopback test function allows users to verify whether transmission path between AMN6300 units is normal. Thanks to these functions, there is no need to construct a dedicated network for remote monitoring and control, nor are measuring instruments required to verify the transmission state. The result is lower maintenance costs and operating costs.
The AMN6300 can be mounted on a standard 19-inch rack together with existing routers. The compact, all-in-one AMN6300, with a height of 3U, incorporates an optical amplifier, a pluggable dispersion compensator, a power supply unit, and fans, in addition to a 40 Gbit/s transmission/reception function. These features reduce the space required for AMN6300 installation at the user's premises and in a data center. Furthermore, reliability of the AMN6300 is ensured because redundant power supply and fan modules are used.
The AMN6300 can operate at either of two voltages: -48 VDC for carrier use or 100 to 250 VAC for enterprise use.
