1. A system comprising:
a first substrate comprising electrical contacts that are configured to be electrically connected to a data processor or electrically connected to a socket or substrate for electrically connecting a data processor, wherein the first substrate has a main surface;
a connector block that is mounted on the first substrate, in which the connector block comprises a first surface and a second surface, the first surface of the connector block is oriented substantially parallel to the main surface of the first substrate, and the second surface of the connector block is oriented at an angle θ1 relative to the main surface of the first substrate, and 45°<θ1<135°,
wherein the connector block comprises a first array of electrical contacts disposed on the first surface and a second array of electrical contacts disposed on the second surface, the first array of electrical contacts are electrically connected to the second array of electrical contacts, and at least a portion of the first array of electrical contacts are configured to be electrically connected to the data processor; and
a pluggable module comprising an optical module, at least one first optical connector, a first fiber optic cable that is optically coupled between the optical module and the first optical connector, and a fiber guide that is positioned between the optical module and the first optical connector and provides mechanical support for the optical module and the first optical connector, wherein the optical module comprises electrical contacts that are electrically connected to the second array of electrical contacts disposed on the second surface of the connector block;
wherein the optical module is configured to receive optical signals from the first optical connector and generate electrical signals based on the received optical signals, and the electrical signals or processed versions of the electrical signals are transmitted to the data processor;
wherein the second array of electrical contacts comprise pairs of electrical contacts, and each pair of electrical contacts are configured to transmit a pair of differential signals;
wherein the first array of electrical contacts is rated to have a data throughput of at least 1 Gbps per lane, the first array of electrical contacts comprise a first pair of electrical contacts configured to transmit a pair of differential signals, the second array of electrical contacts comprise a second pair of electrical contacts, the first pair of electrical contacts are electrically connected to the second pair of electrical contacts through a pair of signal lines positioned internal to the connection block,
wherein the pair of signal lines includes a first signal line and a second signal line, the first signal line has a first length, the second signal line has a second length, and a difference between the first length and the second length is selected such that a skew between signals traveling in the first signal line and the second signal line is less than a symbol period.
