Modern transceivers are designed as hot-pluggable modules. This design gives network engineers the flexibility to upgrade speeds, change wavelengths, or swap out failed. Pluggable optical transceivers are compact, hot-swappable network interface modules that serve as the critical bridge between electronic and optical domains in modern networks. A separate optical cable is plugged into both transceivers. Can an SFP. This guide describes the general handling measures and precautions when handling optical transceivers to ensure they can be handled with reduced risk for damage. They have emerged as a leading interface for current and next-generation network equipment that ranges from current 100 Gb/s to emerging.
