Thank you for your attention and here is the video….

Hello.  I am Dylan, and I am here to talk about the Optical Zonu Micro-OTDR SFP/SFP+ fiber optic transceivers today.

Optical Zonu provides a wide range of MSA Standard transceivers, in various configurations, including Single-Fiber, and Dual-Fiber models, as well as models with Micro-OTDR feature for detecting, locating, and reporting optical fiber faults, a first in the industry.

Our SFPs contain a fully functional Micro-OTDR feature, in MSA standard SFP/SFP+ configurations, which are compatible with any switch in the networking industry for data transport.  What is unique about this, is that we are actually able to provide compatibility a “work-around” Micro-OTDR functionality in third-party equipment by utilizing the Vendor Name field in the EEPROM Page A0 page, so if this equipment is not upgraded to be fully compatible with our Micro-OTDR system, we can replace the Vendor Name in the A0 page, to get that Micro-OTDR functionality, and actually read the optical fiber fault distance.  This provides not only the distance to the faults but also the number of reflections.

In the event of a loss of optical signal (LOS), with one of our Micro-OTDR SFP/SFP+ models installed in your networking equipment, the Micro-OTDR automatically switches over to OTDR mode, the Laser transmitter will emit a pulse a pulse train, while the high sensitivity photodiode receiver (edge-detector) will watch for reflections, and calculate the time in between the outbound pulse, and the received signal, so this measurement can be used to calculate the fault distance, in meters, and count the number of reflections (up to 15).  This can indicate whether there are problems network patch panels, or anything like that, along the optical fiber span.

These SFP/SFP+ models are compatible with our Digital, and RFoF system products, including our S-11 mini-switch, and media converter. This is a managed SNMP device which is capable of interfacing with our other system equipment products, such as our BTS Transport equipment, available in our J-Chassis configuration.

The Micro-OTDR data is available to the host network equipment in several ways.  It can be accessed via command line interface (CLI).  It can be viewed, and controlled, via SNMP.  With a modest firmware/software upgrade of the host equipment, the full capability of the Micro-OTDR feature becomes available.

Optical Zonu provides a wide range of digital, and analog, fiber optic transport solutions.  Please contact us today for more information.
