Reliable Transceiver Modules for Different Connectivity Demands | Hot-pluggable with maximum flexibilityIndependent transceiver design provides the highest network maintenance flexibility. Transceivers can be freely added when required, and infrastructure upgrades or transceiver repairs can be done easily by just replacing the transceiver instead of the whole device.No extra cabling cost to upgrade the fiber plantTraditional fiber optic networking requires two strands of fiber for sending and receiving signals to accomplish communications.The bi-directional, dual-wavelength transceivers can establish communications over just one strand of fiber. Transmission capacity can be expanded immediately without additional cost laying new fiber.Supports digital diagnostics monitoring interface (DDMI)DDMI enables the switch to access operating parameters within the fiber link. This includes digital features such as soft control and monitoring of SFP I/O signals. In addition, the DDMI functionality enables the capability to implement digital alarms and warnings.
