AFL Launches Rugged, Easy-to-Use Variable Optical Attenuator


Spartanburg, SC - AFL is launching the new NOYES® VOA6-SM Variable Optical Attenuator. Designed for telecom and broadband link activation tasks, the VOA6-SM allows the user to "dial in" attenuation values for the purpose of confirming optical link budgets and operating margins or for determining the optical padding value required to match power levels.

Unlike other VOAs in its price range, 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. The VOA6‑SM is calibrated at 1310, 1490, 1550 and 1625 nm, making it ideal for FTTx and other single-mode fiber applications.

"The VOA6-SM was developed to give our customers an alternative to complex and costly laboratory-grade Variable Optical Attenuators," said George Rose, general manager of AFL's Test and Inspection Division. "Its simplicity minimizes training and speeds deployment while its thumbwheel attenuation control allows precise, one-hand operation. We are delighted with the response we have received thus far from our customers."

Ideal for field tasks, the handheld VOA6-SM operates on an internal Li-ion battery and includes a 10-minute auto shutdown, a 60-second backlight power down feature and retains its attenuation setting even while turned off. This permits it to be temporarily installed in a network node should a fixed attenuator be unavailable. The VOA6 SM comes with FC connectors, an AC adapter, a battery charger and carry case.
