12 Fiber Photonic-Plug

A fiber connector product for assembly of optical fibers with silicon photonics chip.

The product is optimized for transceiver products.

Key Features

High assembly tolerance better than ±20µm / 1dB for assembling single-mode fiber ribbon to a silicon photonics chip.

Supports 12 fibers, silicon photonics packaging for transceiver products.

Uses passive assembly protocols and supports high volume packaging using standard semiconductors manufacturing and packaging flows.

Support passive assembly protocols and high volume packaging using standard semiconductor manufacturing and packaging flows.
