    Abstract: Embodiments of the present disclosure include pluggable optical transceiver modules comprising a first interface on a proximate end and eight (8) sockets arranged on a distal end. A first portion of the pluggable optical transceiver module including the proximate end is inserted into a port. A second portion, including the distal end extends outside the port. In one embodiment, an OSFP optical transceiver module include sockets for eight (8) SN or MDC connectors.

    Abstract: Embodiments of the present disclosure include a pluggable optical line system module for amplification, multiplexing, and demultiplexing of coherent optical signals that can be integrated with a switch-router. Integration may include mechanical, electrical, and software control aspects. One example embodiment of the optical line system is in an industry standard small form factor pluggable module such as OSFP (octal small form factor pluggable) or QSFP (quad small form factor pluggable). When configured in a switch-router, the pluggable optical line is powered, managed and controlled by the switch-router which greatly reduces the cost, space, power and the management complexity of optical line systems.

    Abstract: The present disclosure describes a network switch design that includes a vertical switch circuit board that is mounted parallel to the front panel of the network switch. The vertical circuit board supports switch chip(s) to process and forward packets and optical module connectors to receive pluggable optics modules that provide connections to other network switches. The arrangement of the circuit board, switch chip(s) and optical module connectors achieves reduced lengths for the electrical signal traces that connect the switch chip(s) to the optical module connectors. In addition, the design improves cooling by providing separate airflow regions between the switch chip heatsink(s) and the optics modules. The vertical switch card assembly and its components can be made removable from the front panel for ease of servicing.

    Abstract: Embodiments of the present disclosure include optical transmitters and transceivers with improved reliability. In some embodiments, the optical transmitters are used in network devices, such as in conjunction with a network switch. In one embodiment, lasers are operated at low power to improve reliability and power consumption. The output of the laser may be modulated by a non-direct modulator and received by integrated optical components, such as a modulator and/or multiplexer. The output of the optical components may be amplified by a semiconductor optical amplifier (SOA). Various advantageous configurations of lasers, optical components, and SOAs are disclosed. In some embodiments, SOAs are configured as part of a pluggable optical communication module, for example.

    Abstract: The present disclosure describes a network switch design that includes a vertical switch circuit board that is mounted parallel to the front panel of the network switch. The vertical circuit board supports switch chip(s) to process and forward packets and pluggable module connectors to receive pluggable optics modules that provide connections to other network switches. The pluggable module connectors are horizontally oriented to facilitate routing of electrical signal traces. The arrangement of the circuit board, switch chip(s) and pluggable module connectors achieves reduced lengths for the electrical signal traces that connect the switch chip(s) to the pluggable module connectors. The design improves cooling by providing separate airflow regions between the switch chip heatsink(s) and the optics modules.
