NEW 28 Gb/s NRZ Reference Transmitter ModBoxes with a Variable Extinction Ratio


Both Photline 28 Gb/s NRZ 850 nm-ModBox and 28 Gb/s NRZ O-Band ModBox have been reference turn-key transmitters for optical telecommunication laboratories and production test beds. These instruments which provide clean open eye diagrams with above 20 dB SNR, can integrate now the variable extinction ratio option: VER OPTION. This unique feature allows users to set the ER between 3 dB to 12 dB for vertical eye closure, either manually or via computer interface. VER value can be adjusted within the 9 dB range or chosen from standard and pre-set values: 3 dB, 6 dB, 9 dB or 12dB.
