Stratum 1 Network Time Server

Model 8461 from TRAK Microwave, a Smiths Interconnect brand, is a Stratum 1 Network Time Server that is synchronized from an optical IRIG-B DC-level shift link or a wireline Modulated IRIG B link providing time synchronization of <1 µs of time reference. The optical link provides a time synchronization bridge to Isolated Network Domains. The NTP server supports NTP v2, v3, v4 and SNTP clients. An onboard OCXO provides holdover capability in the event that synchronization is lost from the IRIG reference.

Configuration and status of the system can be done through the Ethernet interface using a Web browser, or through a command line using Telnet or SSH. An RS-232 I/O is also available for configuration and status using the command line interface. The Model 8461 can be powered from an external wall plug AC/DC power supply or from Power over Ethernet (PoE) capable switches, drawing 7 watts maximum. The device footprint is a small 5.1” L x 4.7” W x 1.6” H. It weighs less than 1 lb. and can withstand operating temperatures of -40ºC to +85ºC.
