Stratos introduces miniature, ultra-high-density media converters

Included in the Stratos Mini-VMC is a Digital Diagnostics Monitoring Interface (DDMI), for real-time access to critical operating parameters such as module temperature and module supply voltage

Stratos International has introduced a line of slim, small profile Mini-VMC coax-to-fiber and fiber-to-coax digital video media converters. They measure 3.14in x 0.55in diameter and provide conversion between BNC-equipped 75ohm coax and LC-connector-equipped 9µm single mode fiberoptic cable. Smaller in diameter than a BNC connector, the units allow the tightest possible unit-to-unit pitch (port density) available.

These products enable use of fiber transport in HDTV television production, removing the intrinsic distance limitations and signal degradation of coax. Transmitters and receivers are compliant with SMPTE 292M/297M/259M/305M/ 310M protocols, and support data rates from 19.4Mb/s to 1.485Gb/s. Options include CWDM and DFB transmitters.

Included in the Stratos Mini-VMC is a Digital Diagnostics Monitoring Interface (DDMI), for real-time access to critical operating parameters such as module temperature, module supply voltage, received optical power (receiver only), transmitted optical power and laser bias current (transmitter only). DDMI also provides alarm flags to warn when specific operating parameters have been exceeded. This data is accessed via a four-pin XLR-type connector that also provides DC power to the device. A multi-color LED indicator serves as a quick visual indication of Go/No-Go link status and DDMI alarms and warnings.
