Cisco 200G, 100G, WDM Digital CFP2

With the digital version of CFP2 transceiver, both the DSP and the transceiver module reside in the pluggable itself. Therefore, this digital CFP2 pluggable that is more complete and compact, could be used across all platforms with the CFP2 interface.

The compact pluggable formfactor itself allows you to leverage a pay-as-you-grow-model. Also noteworthy is the fact that, contrary to an analog CFP2 where one has to depend on the line card to accommodate the DSP, the digital CFP2 carries the same onboard and allows complete independence in the pay-as-you-grow model.

The TOF allows the pluggable to be used in long reach amplified DWDM systems.

The transmitter has a cold restart timing specification of 50-90 seconds. Cold restart means that the DCO is in a Low Power mode. The maximum Tx turn-up time is counted from the de-assert of the Low power pin and Tx disable pin to full Tx turn-up.

The transmitter has a warm restart timing specification of 4 seconds. Warm restart means that the DCO is in Ready state. The maximum transmitter turn-up time is counted from the de-assert of the Tx disable pin to full Tx turn-up.

The transmitter also has the ability to grid-less tune to any channel in the C-band spectrum. Typical of this is the 96 channel 50GHz spaced tuning that is adopted by many users. The tunability switching time in such a case where you shift from one optical frequency to another including the Tx turn off and turn on time, is 60 seconds. During the tuning period, the Tx power stays at -40dBm.
