Quidway® NetEngine 40E Core Router OC-48c/STM-16c POS Optical Interface Boards
They support hot plugging. The user may add or remove them as needed while the equipment is
powered on without affecting the services of the other interface boards. In addition, hot pluggable
SFP optical modules are adopted for plug and play. The rate can reach 2.5 Gbps. Optical modules
supporting different transmission distances may be selected depending on the networking
requirements.
