This is a question we are often asked by customers in relation to almost all of our products. The answer, of course, is: “It depends”. It depends on several things: The individual product How the product is configured (eg type … Continue reading
At OSD we have been saying for years that singlemode fiber is far better technically than multimode and that the cost premium once seen for SM equipment is slowly starting to disappear. In fact, most of OSD’s new products over … Continue reading
In “the good old days” some things in the world of fiber optics were very, very difficult: fibers were often manufactured with very poor control over physical geometry, impurity levels and doping profiles so that they were usually quite lossy, … Continue reading
Anyone who has read a few of these Tech Corners will have noticed a certain cynicism with respect to the marketing of multimode fibers and our constant exhortation : don’t do it! By almost any measure and in almost all … Continue reading
Fiber equipment suppliers often use two optical wavelengths to enable bidirectional transmission over the one fiber, usually 1310 and 1550nm on singlemode and 850 and 1310nm on multimode. See “Fiber Operating Wavelengths Why so many” for more background information on this. … Continue reading
Abstract CCTV has traditionally used analog transmission to move pictures from cameras to displays. Currently, this technology is slowly succumbing to IP oriented technology although analog-like SDI uncompressed digital systems are gaining traction in some specialised applications. In all cases, … Continue reading
