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.

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.

A network device includes a hardware component. The network device includes a first device receiver operably connected to the hardware component via a first hardware component connection and adapted to receive a device. The network device further includes a second device receiver operably connected to the hardware component via a second hardware component connection. The first device receiver of the network device is adapted to reversibly reallocate the first hardware component connection to the second device receiver.

System and method for reconfigurable network device

A network device is provided. The device includes a housing and a switch card, mounted within the housing and having one or more connectors. A plurality of line cards are oriented parallel to each other and orthogonal to the switch card and assembled to the one or more connectors of the switch card. The switch card has a chip, with a plurality of switches or routing paths, and the switch card and the chip couple to the plurality of line cards through the one or more connectors.

Distributed core switching with orthogonal fabric card and line cards

An optical module includes an optoelectronic transceiver. The optical modules includes a heat sink. The heat sink includes a heat radiating element aligned along a length of the heat sink. The heat sink radiates heat received from the optoelectronic transceiver. The optical modules includes a housing. The optoelectronic transceiver is encapsulated by the heat sink and the housing.

Pluggable optical module with heat sink

An adapter for a communication transceiver is provided. The adapter includes a main body having a first end and opposed second end. The first end of the main body has an OSFP (octal small form factor pluggable) edge connector arranged for electrical and physical connection to an OSFP host connector in an OSFP host port. The main body has a QSFP (quad small form factor pluggable) host connector arranged to receive a QSFP edge connector of a QSFP transceiver through the second end of the main body so that the adapter adapts the QSFP transceiver to an OSFP host. A method of using a communication adapter is also provided.
