*Operation Scheme-1650nm Reflector


 
Description

 

OTDR reflector is located at the Optical Network Unit (ONU) side of a Passive Optical Network (PON), which will reflect the test signal from the OTDR at the Optical Line Terminal (OLT) side, while the traffic signal of the PON system will pass through the reflector with very little loss. OTDR reflector is used to help to increase the sensitivity of the OTDR for checking the optical continuity of a subscriber, and troubleshooting (The reflector has a high reflection ratio and stable reflection, so the OTDR at the CO can obtain a stable peak, and it is possible to calculate the loss of an optical link on a PON network based on the reflection peak). The reflector can be installed at any responsible demarcation point to demarcate faults.

OTDR reflector is based on FBG technology to reflect the OTDR test signal. With wide bandwidth and low insertion loss, FBG reflectors are ideal to create high reflectance of their own intrinsic reflection wavelength at 1645~1655nm at the termination of a PON without disturbing traffic.

 


Features

 

* Fiber Bragg Grating (FBG) Technology

* Low insertion loss and reflectance at traffic wavelength

* High reflective power at a testing wavelength

* SC, LC, FC, or MU plug/jack, Pigtail types are optional, Easy to install

* Space-saving installation on patch panels and/or equipment interface

* Exceptional reliability and environmental stability

* Compatible with EPON, GEPON, GPON, 10G-PON, NG-PON2

* Bidirectional type is optional


 
Applications

 

* Smart ODN

* Create high reflectance at the termination of a PON without disturbing traffic

* Test reflectance from the central office

* Check optical continuity of a subscriber when adding them or troubleshooting

***To measure the Return Loss of the reflecting band, the light of 1650nm should be injected from the female side of the reflector and for the BiDi type, the light of 1650nm can be injected from both sides.

ODN Planning Requirements

 

The length difference between two links must be greater than 1.5 times the split ratio of the second-level optical splitter on the shorter link. This ensures that the distance between any two reflectors is longer than 1.5 m so that reflection events on an OTDR test curve will not overlap.

*If L1 is less than L2, the difference between L1 and L2 must be greater than 1.5 x N1.

 

 

 

Application Scenario

 

* During project engineering, optical fiber carriers use a reflector and the Field Assistant to check the installation by phase, thereby implementing comprehensive ODN quality acceptance.

* CO engineers confirm acceptance results and create a data file of the optical fiber network project and maintain the file, which supports fast fault demarcation and location during a follow-up operation.

B: Output port on a second-level optical splitter

C: Drop Terminal port or ONU port

 

 

Main Flow of an ODN Acceptance Test

 

1. Deploy a feeder fiber and install a first-level optical splitter.

2. Install a reflector at point A and perform acceptance tests on the first-level optical splitter.

3. Remove the reflector at point A.

4. Deploy distribution fibers and install second-level optical splitters.

5. Install a reflector at point B and perform acceptance tests on the second-level optical splitter.

6. Remove the reflector at point B.

7. Deploy drop fibers and a Drop Terminal.

8. Install a reflector at point C and perform reflector loss tests.

9. (Optional) Retain the reflector at point C for follow-up line tests.
