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. 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. www.AFLglobal.com
