What is SPECIAL about the Micro-OTDR™?
Fast Fiber Fault Finder™
- Standard SFP / SFP+ format fits in any networking equipment.
- When link breaks – distance to fault is availabl.
- The configuration is standard: SFP/SFP+ (Small Form-Factor Pluggable). When the fiber is cut, disconnected or broken the distance to the break point is instantly reported
- Data rates are FE, OC3, GbE, OC48, and 10G
- Immediate plug-in replacement of an existing SFP/SFP+
- Automatically generates Link “Birth Certificate”
- Fast Response Time.
- Supports Interactive Mapping Capability.
- OpEx Reduction.
- Reduced Network Down-Time.
Overview:
- Standard SFP (MSA Form Factor) links automatically (like any SFP) with a counterpart at the other end of the optical fiber link
- Upon detecting a link “break”, or fault, the unit transforms into a Micro-OTDR™
- For the single fiber version – patented single wavelength duplex CWDM transport
- High optical power pulses are sent and sensitive circuitry measures all reflections detected
- Internal processing eliminates false detection, and ensures reliable measurement of more
than 10 reflection points (e.g. bad splice, micro crack, dirty connectors, etc.) - All results are available, via IIC bus of the SFP, to the host Switch
- Our S11 media converter enables demonstration and retention of the optical fiber link “birth
certificate” (the initial measurement of the link distance, and any reflections) and SNMP creates “traps” of any change in the optical fiber link status - A special feature called Delta Power Sense (DPS), detects fast optical transients and intrusion
attempts - When a fault is detected (LOS goes High), the Micro-OTDR™ SFP automatically changes over
to Micro-OTDR™ mode. It will return to data transport mode when the fault is resolved (i.e.
LOS goes Low)

Our single fiber (iSFC®) and dual fiber (iDFC™) Micro-OTDR™ SFP Transceivers support all eighteen (18) CWDM Wavelengths, plus the 1625 nm monitor channel for operation above the C-Band and CWDM data channels. The identical part number model is used on both sides of the optical fiber link, that is, there is no requirement for matched pairs, or complementary pairs. This means fewer SKUs to inventory, track and manage, as well as, less splicing in the field, simplified fiber optics inventory and higher Network Reliability. Complete end-to-end optical link ZonuColor Coding simplifies operation, reduces installation time and reduces installation errors. Our unique RIO® feature eliminates reflection problems which plague legacy single fiber, single wavelength (SFSW) SFPs. Reflection Immune Operation – RIO®
The Delta Power Sense (DPS™) function detects instantaneous optical spikes (i.e. fast changes in optical power, up or down). Delta Power Sense (DPS™) The Micro-OTDR™ – μOTDR™ is a new Approach to Optical Fiber Fault Monitoring – SFP and SFP+ Transceivers with a built-in automatic OTDR feature. Micro-OTDR™ – μOTDR™ To improve the reliability of the Access Network, fault detection must be fast, distributed and pervasive.
