Lantronix provides advanced optical solutions through Intelligent Optical Transceivers. The portfolio includes an SFP with integrated Micro-OTDR that automatically detects, locates and reports optical fiber faults when installed in a suitable switch. The SFP is designed in conformance with the Small Form Factor Pluggable 20-pin Multi-Source Agreement (MSA) 2 types of OTDR SFP are available Single fiber and Dual fiber. The Single Fiber Single Frequency transceivers transmit and receive at the same wavelength effectively doubling the optical fiber plant capacity. Upon disruption of data link, or failure to connect, the unit switches into uOTDR Mode, emitting optical power pulses (more than +13 dBm) and detecting the reflected pulses at least down to -42 dBm optical power. Reflection Immune Operation resolves self-reflection from an open connector and / or other reflectors.
