Small Form Factor Pinning Comparison
The drawing below gives you a comparison between the different pinnings 2x5, 2x6,
2x10. Dimension for diameter and distance of additional pins is similar to the existing
dimensions of the other pins.

Pin Description
RS pin - The RS Rate Select: is not connected.
LF pin - The LF pin (Laser Fault) is a TTL output of the Laser Driver Supervisor Circuit.
A Logic “1” level can be measured in case of a laser fault. It will not show a fault
if the laser is being disabled using the TxDis input, since this is not a fault
condition.
EMI-Recommendation
To avoid electromagnetic radiation exceeding the required limits please take note of the
following recommendations.
When Gigabit switching components are found on a PCB (multiplexers, clock recoveries
etc.) any opening of the chassis may produce radiation also at chassis slots other than
that of the device itself. Thus every mechanical opening or aperture should be as small
as possible.
On the board itself every data connection should be an impedance matched line (e.g.
strip line, coplanar strip line). Data, Datanot should be routed symmetrically, vias should
be avoided. A terminating resistor of 100 Ω should be placed at the end of each matched
