Fibre-Lyte 40Gb/s MPO 4Tx+4Rx

Fibre-Lyte is an optoelectronic packaging technology which can be used to interface with MT connectors. It can package a wide range of VCSELs, detectors and many other chips from low to high power.

This 4Tx+4Rx MPO part is a standard design (order code CJT-Qxx-V7-40 B-B-A B) which acts as a fully programmable transceiver. It transmits 4 optical channels of 10Gb/s each and also receives 4 optical channels at 10Gb/s each. Please see the functional block diagram for further detail.

Conjunct provides pre-drilled pin holes for ease of assembly to both fibre and PCB. Optical coupling uses either an embedded lenses or optical waveguides.s

Note that Conjunct does not fabricate optoelectronic die but packages them. Fibre-Lyte can be used in transceivers, active-optical cables (AOC) or directly attached to PCB in a custom application. If you have a particular die combination or custom application please contact us for a quote.
