Stratos Lightwave LLC recently released a new line of Bulkhead Media Converters (BMCs) for harsh environment applications.

The converters accept a standard optical signal such as Fast Ethernet, and convert it to an industry standard signal such as IEEE802.3u (100BT). The devices handle both the optical-to-electrical and the full physical layer (PHY) conversion.

According to the company, they decrease the engineer’s overall design burden by removing all “inside-the-box” fiber management.

Inside the box, any circuit board or subsystem equipped with CAT5/RJ45 modular jack cabling is plugged directly into the backshell of the BMC unit.

The Stratos Bulkhead Media Converter line consists of a number of standard options, including Gigabit Ethernet and Fast Ethernet media conversion using the standard RJ-45 interface connection.

Other variations include Ethernet MII or GMII ribbon cable interfaces, and 1x/2x Fiber channel transceivers with a ribbon cable interface on the electrical side.

Maximum optical link distance is 2 kilometres for Fast Ethernet, and 550 metres for Gigabit Ethernet. They are available for either 62.5/125 or 50/125 micron multi-mode fiber, and can be equipped with one to four optical channels, in various combinations of simplex and duplex configurations.

The units have an operating temperature range of -40 degrees C to +85 degrees C, and meet MIL-STD-810E for shock and vibration. Immersion rating is two hours at 1 meter (MIL-STD-810E).
