Mini-TOSAs
Our mini-TOSA (transmission optical sub-assembly) is built on a 3.8mm CAN, designed for use in the small form factor, and small form pluggable MSA transceiver modules.
We have a full range of devices for every standard bit-rate and distance. Additionally, our TOSAs operate over the
full industrial temperature range (-40 to 85°C). Couple this with Sumitomo's high reliability, and we have a proven winner.
