Other Considerations
SFP MSA Compliance
The SFP Multisource Agreement (MSA) is an agreement that was drafted among competing manufacturers of
SFP optical modules. The SFF Committee was formed to oversee the creation and maintenance of these
agreements including the SFP MSA designated as INF‐8074i. This agreement describes a mutually agreed upon
standard for the form and function of SFP modules. However, not all SFPs produced are MSA compliant. The
MSA provides for a transceiver (TX/RX) pinout. Other industries such as broadcast had the need for dual TX
and dual RX SFP for uni‐directional applications such as video. Naturally, a non‐MSA standard was introduced
allocating pinout assignments for dual output and dual input I/O configurations. In addition, the some of the
internal serial communication pins were reassigned.
The FOM‐3841/3842 will only accept MSA compliant SFP Modules.
