44-port 1GigE CSFP/SFP MDA-a Overview
168 7750 SR-a4 and SR-a8 Installation Guide
If more than 25 ports are in use, the per-port maximum simultaneous line rates diminishes as
a ratio of 25 Gb/s divided by the number of ports in use. For example, if all 44 ports are
installed and are run at full speed, the line rate is approximately 25 Gb/s divided by 44 ports,
which is 560 Mb/s per port.
The card is limited to 25 Gb/s; installing the card in a 100 Gb/s slot does not increase the
throughput.

Power Consumption
Table 86 lists the power consumption values for the 44-port 1GigE CSFP/SFP MDA-a.
Note:
1. Idle: Slots not configured or provisioned
2. Zero Traffic: Traffic load: 0% line rate at 25ºC (reset case)
3. Typical: Traffic load: 50% line rate with Internet mix (IMIX) at 25ºC
4. Worst Case: Traffic Load: 100% line rate with IMIX at the maximum short duration and at a high temperature
(65ºC)
