Ultra Electronics-DNE Technologies announces the release of a new Secure Digital Voice Order Wire Interface option module for the CV-MCU product line. The new module, called the CV-FOM-D/OW, passes Secure Digital Voice Order Wire traffic to and from a cryptographic unit or an Enhanced Tactical Satellite Signal Processor (ETSSP) using a standard fiber-optic cable link. Combining this new feature with NRZ, CDI, and FOM conversions allows an orderwire device to be co-located with remote NRZ equipment. This feature, when used with an IP-based network manager, permits remote operation of a communications van or shelter. The push to talk (PTT) functionality of cryptographic units, such as a KY-57 or a KY-99A, is also supported. The new CV-FOM-D/OW module is the latest in a series available for the CV-MCU, and can be installed in any deployed CV-MCU to add orderwire functionality to any new or existing fiber link.

Like all CV-MCU option modules, DNE’s CV-FOM-D/OW economically combines the features of both Conditioned Di-Phase Modems (CDIMs) and Fiber Optic Modems (FOMs), and also offers a conversion to and from Non-Return to Zero (NRZ) protocols. By allowing NRZ devices to be positioned at significant distances from the satellite terminal, the CV-MCU modules support both TRI-TAC digital trunk groups and new, emerging technologies while utilizing the reliability and economy of tactical fiber connections.

DNE’s CV-MCU increases deployment flexibility and reduces the long-term cost of ownership through a unique design that allows a simple, inexpensive upgrade or system re-allocation of current assets without removing and recabling each installed chassis. Each lightweight, aluminum 1-U CV-MCU rack-mount chassis handles two independent circuit modules that can be configured for separate applications. Each individual circuit within the CV-MCU can be upgraded independently, allowing modules with distinct applications to reside in the same chassis. The circuit modules are also hot-swappable, further minimizing system down time. This modular feature provides an inexpensive and simple upgrade path to additional compatibilities while preserving interoperability with fielded protocol conversion units.

The CV-FOM-D/OW module supports JTC3A-9109C tactical fiber interoperability at traffic rates up to 16.384 Mbps, with singlemode and multimode fiber supported by a universal 9/50/62.5µm, 125µm @1310nm ST connectors. Optional TFOCA and TFOCA-II interface assemblies are also available. The CV-FOM-D/OW module is also compatible with earlier converters from DNE, including the CV-2048 and the CV-8448, at rates offered by both units.
