Problems solved by technology

[0003] The existing QSFP28 module does not have CDR technology, and directly uses cables to connect one QSFP28 interface to another QSFP28 interface, but this connection method has the following disadvantages: 1. Since the existing QSFP28 module does not use CDR technology, Resulting in poor transmission performance and short transmission distance; 2. The existing QSFP28 module is only connected to another QSFP28 interface through a cable, but not interconnected with other types of module interfaces, so it cannot be applied to a variety of different interface types The connection between the HOST terminals, the electrical connection is single, and the practicability is poor

Abstract

The invention discloses a 100G cable module based on a QSFP28 interface. The 100G cable module comprises the QSFP28 interface, a CDR reception module, an MCU, and a cable interface, the CDR reception module is respectively connected with the cable interface and the QSFP28 interface and used for receiving first signals sent by the cable interface, the CDR reception module converts the first signals to first processing signals and sends the first processing signals to the QSFP28 interface, the MCU is respectively connected with the CDR reception module and the QSFP28 interface and used for sending first control information to control the operation of the CDR reception module, the CDR reception module is also used for sending first state signals to the MCU, the MCU is also used for processing the first state signals or sending the first state signals to a host computer for processing via the QSFP28 interface, and the CDR reception module is also used for receiving second control information sent by the host computer via the QSFP28 interface. According to the 100G cable module, the CDR module is additionally provided so that the overall transmission performance of the module is good, and the transmission distance is long.

Description

technical field [0001] The invention relates to the field of optical modules, in particular to a 100G cable module based on a QSFP28 interface. Background technique [0002] The development of the information industry has put forward higher requirements for high-speed transmission, which requires optical modules to have better transmission performance and flexibility to correspond to various electrical interfaces. [0003] The existing QSFP28 module does not have CDR technology, and directly uses cables to connect one QSFP28 interface to another QSFP28 interface, but this connection method has the following disadvantages: 1. Since the existing QSFP28 module does not use CDR technology, Resulting in poor transmission performance and short transmission distance; 2. The existing QSFP28 module is only connected to another QSFP28 interface through a cable, but not interconnected with other types of module interfaces, so it cannot be applied to a variety of different interface typ...
