LGX Cassette OM3 36 LC
This Black Box LGX cassette provides 36 LC connectors arranged as 18 duplex pairs fed by three 12-strand MTP connectors. It uses OM3 multimode fibre and follows method A polarity wiring. The unit fits the High-Density 108 LC Enclosure for rack mounting.
Installers needing method A polarity
Engineers who require method B or method C polarity wiring should select a different cassette because this model is fixed to method A. Networks that run on single-mode fibre or OM4/OM5 grades also need a separate part.
Insertion loss LC 0.3 dB MTP 0.75 dB
LC connectors present a maximum insertion loss of 0.3 dB at 850/1300 nm while the MTP interfaces are rated at 0.75 dB max at the same wavelengths. These figures determine whether the cassette meets your link-loss budget.

Questions about this item
Does the 36 LC adapter panel generate any heat or noise when installed in a rack?
The cassette is completely passive with no moving parts or electronics, so it produces no heat or noise during continuous operation.
What patch cords or enclosures must I already have to use the three 12-strand MTP connectors wired to method A?
You need 12-fibre MTP patch cables with Type A polarity and an LGX-compatible enclosure such as the High-Density 108 LC Enclosure (FOEN50HD-3H-1U).
Will the 0.3 dB LC and 0.75 dB MTP insertion loss figures work with my existing OM3 links at 850 nm and 1300 nm?
Yes, the stated maximum losses at 850 nm and 1300 nm are within typical OM3 link budgets, so the cassette will not add unexpected attenuation to your current runs.
