MPO Gender
MPOs
are classified by the guide pins on the end of the connector, and
require 1 male and 1 female to mate properly. MPO connectors use a
“barrel sleeve” adapter that simply holds one male and one female MPO
“plug” together. The male guide pins fit into the female holes to ensure
precise fiber alignment. Attempting to mate two female connectors will
result in a seemingly secure connection, but with extremely high loss,
and attempting to mate two male connectors will most likely damage one
or both connectors due to the guide pins clashing.
Transceivers
and cassettes come with the sleeve adapter built in, and the industry
standard is a male conection on the inside. Therefore, the standard for
cables is female to female. This changes, however, when you need to
extend a cable or connect two cables. You will then need a male to
female cable plus adapter. If you’re designing a multi-ferrule MPO trunk
backbone cable, you might consider making this male to male, then
patching to your hardware with female to female cables. We offer all
combinations of genders, so contact us with your needs and we will be
able to customize these for you.

MPO Polarity
There
is typically only 1 common polarity method in the construction of
24-fiber MPO/MTP style patchcords – Straight. The schematic below
attempts to visually show how this polarity method is configured. Custom
configurations are also available upon request.
24
Fiber MPO cables are most often used in 100G CFP/CXP applications.
Transceivers utilize the inside 10 fibers on each row, with Rx on the
top row (2-11) and Tx on the bottom row (14-23). Our cables are built
with all 24 fibers for additional use with cassettes or other
applications. The key-up to key-down configuration sends the top row to
the bottom and vice versa.
