Transceiver body marking

YB, Thank you for posting on the Intel® communities.

Based on the product part number "MPN PEF2256HV2X", this seems to be related to Intel® PRI Transceiver.

We would like to inform you that we have a forum for those specific issues and products, so we are moving it to the "FPGA, SoC, And CPLD Boards And Kits" forum so you can get the answer more quickly:
