OP752-MOD Modal Conditioner
This modal conditioner unit ensures correct launch
into 50/125 multimode fiber to meet IEC encircled flux requirement.

|
For multimode insertion loss measurements
the LED sources are either conditioned to meet IEC launch condition
for 50/125 fiber or 62.5/125 fiber. With the OP752-Mod the launch
of a 62.5/125 is converted into the proper lunch for 50/125 fiber
and ensures the correct launch per IEC.
A typical Encircled Flux example for 50um multimode fiber @1300nm is shown below:
| 62.5/125/250 MM GI |
| 50/125/250 MM GI |
| typ. 3dB |
| better than 30dB |
| per IEC draft 14763-3 |
| up to 24 per unit |
