*1: G8339/G8342 series cannot be operated with RL=50 Ω, so they should be used with a load resistance larger than 500 Ω.

*2: Single ended (Vout+) measurement using a single mode optical fiber with a master plug.

*3: G8339/G8342 series: Pin= -30 dBm

G7881 series: Pin= -22 dBm

G8796 series: Pin= -17 dBm
