Switches offer media module, 80 ns synchronization accuracy.

Press Release Summary:

MICE series of Hirschmann(TM) switches are available with media module, which supports Precision Time Protocol (PTP) according to IEEE 1588 V2 and offers synchronization accuracy of less than 80 nsec even in large, cascaded networks. Suited for use in any data network requiring real-time capability, module can also be equipped with electrical port and optical transceiver. It provides 2 RJ45 (10/100/1000 BASE-TX) or 2 SFP fiber optical transceiver (1000 BASE SX/LX) interfaces.

Original Press Release:

Belden Expands its Hirschmann(TM) Product Portfolio with a New Media Module for Switches of the MICE Family: Synchronization Accuracy in the Nanoseconds Range

The new media module supports the Precision Time Protocol (PTP) according to IEEE 1588 V2 and offers a synchronization accuracy of less than 80 nanoseconds even in large, cascaded networks.

In addition, the module can also be equipped with an electrical port and an optical transceiver, permitting the connection of other networking components or field devices using twisted-pair cables as well as multi-mode or single mode fibers. The new media module is ideally suitable for use in any data network requiring extremely high real-time capability, such as in measuring technology or drive control. With a software update, available for download free of charge at www.beldensolutions.com, the module can also be used in switches of the MS 20/30 series.

The media module has an MTBF (Mean Time Between Failures) value of 28.1 years, is designed for an operating temperature range of -10 to +60 °C, and can be commissioned by plug-and-play. A hot swap function also permits live replacement during operation, if required. Operating parameters are displayed by an array of LEDs on the front panel. Large label fields are available for customized designation of each module as well as clear allocation of ports.

Specially designed for operation in rugged industrial environments, the MICE family of Hirschmann(TM) switches consists of a switch unit with an integrated back plane that can be equipped with various different media modules. They support Fast and Gigabit Ethernet as well as numerous routing, redundancy and security modes. Passive cooling (no fans) and a redundant 24VDC power supply add to ensure high operational safety. Since the switches can be mounted on standard top-hat rails, they have a perfect fit both in central control cabinets and in peripheral distribution boxes. The new media module provides two RJ45 (10/100/1000 BASE-TX) or two SFP fiber optical transceiver (1000 BASE SX/LX).

PTP V2 has once again clearly raised the synchronization accuracy over its predecessor version. "Above all, this results from the Transparent Clock function introduced in addition to Boundary Clock and Ordinary Clock, which now also permits end-to-end synchronization," explains Product Manager Pascal Unterdorfer. "This means that virtually all runtime jitter and latency can be compensated in the switches, achieving maximum synchronization accuracy even in very large networks."
