Huawei S series devices support optical modules of the following encapsulation types: CFP, QSFP+, QSFP28, XFP, SFP, eSFP, and SFP+. All optical modules are hot swappable. They comply with the specifications defined in the multi-source agreement (MSA) and support synchronous optical network (SONET), Gigabit Ethernet (GE), fiber channel, and other communication. An optical module is a component that completes electrical/optical conversion on an optical network. Figure. The hot-pluggable feature of optical transceivers allows for rapid replacement, upgrade, or reconfiguration without powering down network equipment. This functionality is not just a convenience—it's an engineering design requirement in scalable, modern networks. What Does "Hot-Pluggable" Mean. These small modules determine how your uplinks operate: the speed, the distance supported, and whether your Cisco or Huawei switch will even recognize the module at all. eSFP: enhanced small form-factor pluggable. An eSFP module is an SFP module that supports monitoring of voltage, temperature, bias current, transmit optical power, and receive optical power.
