10GBASE LR Link Budgeting

[KESHAV METHI]

Hi,

I am using 10Gig link to connect distribution and access switches. Since we are terminating the cables at multiple locations, we are also doing the link budgeting. The CISCO SFP 10G-LR module data sheet shows two values for the transmit power one of which is maximum power .5dBm and another is minimum power -8.2 dBm. Kindly advise which value should I choose for the link budgeting.

Hi,

for LR, if you use 0.5 for transmit and receive,  you should be fine.

Have a look at table-B-13 in this link:
