The OC-48c/STM-16c POS optical interface board is hot-pluggable. You can install or remove
interface boards while the NE5000E is powered on, without affecting services of other interface
boards. Hot-pluggable and plug-and-play SFP optical modules can be used on the
OC-48c/STM-16c POS optical interface board, achieving a rate of 2.5 Gbps. You can choose
optical modules with different transmission distances according to networking requirements.
