PRODUCT DESCRIPTION
The SFP+ LR module electrical interface is compliant to SFI
electrical specifications. The transmitter input and receiver
output impedance is 100 Ohms differential. Data lines are
internally AC coupled. The module provides differential termination
and reduce differential to common mode conversion for quality
signal termination and low EMI. SFI typically operates over 200 mm
of improved FR4 material or up to about 150mmof standard FR4 with
one connector.
