The WDM Lite
(TM) Optical
Return Loss Meter Adapter is the industry's first ORL adapter of its kind. This completely passive
and rugged field unit allows technicians to measure
the optical return loss (ORL) of an optical fiber.
This unit can also be used to measure the ORL of
a WDM or DWDM fiber or channel.
The ORL Adapter allows a standard
optical power meter and source to be used to measure
the optical return loss (ORL) in a fiber. The test
set connects to its appropriate ports on the adapter,
and the fiber to be tested connects to the Fiber
Under Test (FUT) port of the ORL Meter Adapter.

| Features: |
|
- Converts existing optical power meter and source
to measure optical return powe
- Completely passive, no batteries required
- Rugged, designed for field use
- Can measure ORL in WDM and DWDM systems
- Can measure absolute reflected power values
- Easy to use, no adjustments required
|
|
| Applications: |
- Application includes testing SONET, DWDM, Video,
AM, ATM systems
|
| |
| The fiber’s optical return loss is calculated
using the below formula from the readings that are
recorded on the power meter. |
| [ORL]dB
= [Optical Source]dBm - [Optical Power Meter]dBm
- 1 dB |
| For measuring absolute ORL or ORL in a WDM/DWDM
channel, the laser transmitter of the communication
system is used as the Optical Source. The Absolute
Returned Optical Power is calculated as: |
|
[Absolute
Returned Optical Power]dBm = [Optical Power Meter]dBm
+ 1 dB |
| DWDM/WDM ORL is: |
|
[WDM ORL]dB
= [Optical Power of DWDM Laser]dBm - [Optical Power
Meter]dBm - 1 dB |
