Receptacle configuration to support on-board receiver optical subassembly (ROSA)

An optical transceiver comprising:

• a substrate defined by first and second surfaces disposed opposite each other;
• a receiver optical subassembly (ROSA) arrangement disposed on the first surface of the substrate, the ROSA arrangement to receive a multi-channel optical signal and output an electrical signal representative of each channel wavelength of the multi-channel signal;
• and
• an optical fiber receptacle coupled to an end of the substrate, wherein the optical fiber receptacle includes:
• a body;
• an aperture defined by the body and extending therethrough, the aperture being a through hole with a generally cylindrical shape and configured to receive and couple to an optical fiber ferrule of an optical fiber;
• and
• a slot defined by the body, the slot extending substantially transverse relative to the through hole, the slot configured to at least partially receive a portion of the substrate that includes the first and second surfaces to couple the substrate to the body, and wherein the through hole is configured to receive the optical fiber ferrule and optically align light emitted by the optical fiber with the ROSA arrangement disposed on the first surface of the substrate based at least in part on the through hole extending through the body along a longitudinal axis that is substantially parallel to the surface of the substrate when the substrate is received within the slot and coupled to the body such that the light emitted by the optical fiber travels along the longitudinal axis and intersects with at least one component of the ROSA arrangement disposed on the first surface of the substrate;
• and
• a transmitter optical subassembly (TOSA) mounted to the substrate.
