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.
Improved text for What is SPECIAL about the Micro-OTDR?
Every telecommunications optical fiber link needs to be monitored, but not every monitored optical fiber link needs a Remote Fiber Test System (RFTS).
In Metro Edge Networks where traffic flows of 20 Km to 100 Km dominate, ISPs, Dark Fiber Providers and Enterprises need a thrifty approach to optical fiber monitoring, without all the
unnecessary “extras”.
This is where the OZC Micro-OTDR™ feature comes into play monitoring the network… keeping it simple:
What is the status?
Where is the problem?
This is what the Network Operations Center (NOC) needs to know, and know immediately. With Micro-OTDR SFP/SFP+ transceivers deployed at every node, the Micro-OTDR™ feature instantaneously detects faults, calculates the distance to the faults, and stores the results in the Micro-OTDR™ SFP/SFP+ EEPROM
With the Micro-OTDR™ Link Birth Certificate as a reference, created at the time of the optical fiber link installation, the nature of the fault can be immediately known:.
Is the fault in the optical fiber link? => Dispatch the field optical fiber Techs.
Is the fault in the remote facility? => Notify the network equipment Techs.
OPEX savings with the Micro-OTDR™ can be inherently better than 25% (only one Truck roll per event required) and the overall CAPEX savings can be significant (the Micro-OTDR™ also transports network revenue data).
In short, the Micro-OTDR™ feature is Fast, Distributed, Pervasive, Low Cost and Revenue Generating.
