ZonuFx Smart SFC Micro-OTDR Fast Fiber Fault Finder

Single Fiber, Full Duplex, CWDM, SFP Transceivers with Built-In OTDR

The ZonuFx functions as a normal Single Fiber, Full Duplex CWDM Transceiver, but with the ability to switch into operation as a Smart SFC Micro-OTDR capable of detecting and localizing optical fiber faults.

ZonuFx Smart SFC Transceivers transmit and receive at the same wavelength, which allows them be used for Optical Fiber Fault Detection and Localization. The ZonuFx transmitter can be switched to operate in Micro-OTDR mode where it transmits optical pulses of +13 dBm. The receiver will detect any reflected pulses down to -42 dBm optical power.  Total ORL detection range is at least 55dB, enabling detection of fiber break/cut.

Open fiber reflections in a “Blue” UPC Connector Network are about 15 dB in magnitude. The Micro-OTDR Mode (with an optical power detection budget of more than 55 dB) can detect the open fiber fault up to the full reference link distance (including 4-Ch or 8-Ch Mux/Dmux). The ZonuFx monitors the time delay between the transmitted and reflected pulses, such that the position of the fault may be accurately determined.

The fault localization accuracy can be within 20 meters. This location data is instantly reported to the host switch/router via the ZonuFx DDM function. This allows the immediate targeted response necessary to support enhanced Network Security and deliver superior Service Levels.  The distance to fault can be read via SNMP of the switch family OZC supports.

ZonuFx Smart SFC Transceivers

The SFC/P2P Transceivers at the heart of the ZonuFx also provide Full Duplex Transmission of Industry Standard Protocols (IEEE 802 Fast Ethernet, Gigabit Ethernet and CWDM10-Gigabit Ethernet; SONET OC-3/12/48; SDH STM-1/4/16) over a Single Fiber. The ZonuFx comes in the industry standard SFP configuration, compatible with Networking gear from all the major OEMs.

Benefits to the Bottom Line

SFC is the Edge Access Network Solution for delivery of Fiber Optic Commercial Data (IP/MPLS/Ethernet) Services in “Fiber-Starved” HFC and other Telecommunications Networks. OZC provides SFC Technology with a complete line of Products for Business Class Commercial Services. The OZC Value Proposition is that our SFC Technology DOUBLES Optical Fiber Capacity (compared to legacy CWDM implementations) and delivers Operational Benefits to Improve the Service Provider’s ROI, over both the short and long term. The ZonuFx need only occupy one ITU Channel on a CWDM “bundle” of wavelengths. For example, a single BLK 1551 nm ZonuFx monitors the entire CWDM “bundle”, since all of the CWDM “colors” propagate down the same physical optical fiber. Also, the ZonuFx need only be at one end of the link for the Micro-OTDR to do its job. It might be located just in the Headend, Hub or Central Office.
