AFL unveils Noyes VOA6-SM Variable Optical Attenuator
By Alyssa Dalton
September 14, 2011 – AFL has debuted the Noyes VOA6-SM Variable Optical Attenuator, which allows the user to “dial in” attenuation values to confirm optical link budgets and operating margins, or for determining the optical padding value required to match power levels, it says. According to AFL, the 45 dB Optical Return Loss of the VOA6-SM makes it the best choice for use with DFB-based transmitters and other devices that can be damaged or degraded by higher levels of reflected power. It is calibrated at 1310, 1490, 1550 and 1625 nm.
