Fiber management system

Fiber diagnosis system


Case 1 NTT-EAST: 20% troubles occurred in OSP Case 2 An EMEA carrier with 1M FTTH subscribers: 20% failures caused by connection mismatch

Case 3 A Chinese carrier: 25 minutes on Avg. spent on connection identification Several hours taken to solve a problem on manual

Cases Prove Fiber Troubles Take Big Share of OPEX in Current FTTH

26% Troubles from mechanical splicing

26% Troubles from underground connectors

48% Damages from third parties, natural disaster and living things, etc.

Fiber Management Technologies in Discussion

Tech. Key Features Industrial Status

Barcode Barcode reader connected with DB Record and verify connection

relationship after operation

Recommendation in ITU-T SG15/L.64

RFID

Using special RFID reader in the fiber plugging tool

Automatic navigation with LED Automatic record every single

operation

Recommendation in ITU-T SG15/L.64

eID

Using contacting of two eIDs toidentify the connections in batch

Connection/Topology awareness Automatic navigation with LED

Proposal in ITU-T SG15 Q17/15


eID Written in Factory eID Definition

Connector ID(64bit)

Connector Info.(72bit)

Information can be uploaded to ODN management system via iField


An eID Tag Based Intelligent ODN

iODF/iFDT/iFAT can be managed by ODN management system via iField.

All the information can be managed by use of eID tech. and shared to systems such as IS,CRM, etc.

High efficiency: test fibers in batch instead of one by one; Reliable acceptance result: bundling test result with each line

and then upload info to database automatically.

ONT

iODN output reliable network topology for fault demarcation Determine fault distance through OLS system iODN output reliable site GIS information for fault location

iODN Can Be Facilitated Also by OLS Solution

OTU


Inefficient fiber management of ODN results in higher FTTH OPEX.

An eID based fiber management approach is under discussion; proposal accepted in ITU-T SG15 Q17/15

In addition to fiber management, iODN can also be leveraged for intelligent line acceptance certification system and OLS.
