Here's the mass of the SPI pathfinder's ISIK transceiver that will be suspended on HAM3.

10.958 [kg] :: Fully assembled ISIK Transceiver (D2400107)
    - no installation handles
    - no baffle bracketry
    - sensor/actuator cabling draped to the side

0.898 [kg] :: Fully assembled portion of in-vac cabling that will be suspended on Stage 1 of HAM3 ISI
    - includes cable table brackets
    - excludes QTY 2x D25 to D25 signal bus cables that span ST1 to ST0 to Feedthru.

0.703 [kg] :: Fully assembled portion of in-vac fiber optic cabling that will be suspended on Stage 1 of HAM3 ISI
    - 0.570 [kg] :: QTY 2x will be suspended so expect 2x0.285 = 0.570 [kg]
       . 0.285 [kg] :: QTY 1x Fiber spool (what was actually measured, rather than two)
       . Most of the optical fiber, plus wont-be-there fiber mating sleeve and cap
    - 0.133 [kg] :: QTY 2x Fiber spool assembly feet and installation hardware: 

12.599 [kg] :: Total suspended mass.

All this mass will be on the -X side wall of the ISI, below the optical table, as shown in D2400103.

We have not measured the mass of any component of the ISIK shroud assembly D2400106.
