    Crossover cable: The twisted pairs in the RJ45 connectors at two ends are crimped in different sequences. A crossover cable connects two devices or interfaces of the same type, for example, two PCs. Huawei switches support both straight-through and crossover cables and their ports are adaptive to the cable types. Appearance and Structure NOTE l Generally, a network cable is a standard unshielded network cable that uses RJ45 connectors.

    If the optical modules you use are delivered after July 1, 2013, use either of the following methods to determine whether they have been certified by Huawei. Method 1: Check for "HUAWEI" on the Label If an optical module has been certified by Huawei, its label contains "HAUWEI", as shown in Figure 4-1.

  • Page 51: Risks Of Using Non-Huawei-Certified Optical Modules

    As a result, data on the suspended bus cannot be read. Improper edge connector size damages electronic devices of optical interfaces. If a non-Huawei-certified optical module with improper edge connector size is used on an optical interface, electronic devices of the optical interface will be damaged by short circuits.

  • Page 52: Understanding Optical Modules

    Optical modules are available in various types to meet diversified requirements. Classified by transmission rates Depending on transmission rates, optical modules are classified into FE, GE, 10GE, and 40GE optical modules. Classified by encapsulation types Issue 07 (2014-10-25) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.
  • Page 53 4 Pluggable Modules for Interfaces The higher transmission rate an optical module provides, the more complex structure it has. Optical modules are encapsulated in different modes to provide different structures. Huawei switches support optical modules of the following encapsulation types: SFP, eSFP, SFP+, XFP, and QSFP+.
