A Volume Holographic Grating Diplexer (VHGD) is an optical element that diffracts the downstream 1490nm signal while allowing the 1310nm upstream signal to go through.
Compared to thin film interference filter, the VHGD enables the 1310nm transmitter laser (TX) and the receiver (RX) to be on the same side, either on the same plane or at different heights, thus enabling low cost packaging.

Applications |
- Highly stable and reliable with over 12,000 hours of testing at 150 degree C
- 0.1 dB transmission loss
- Custom size and angles between the two beams

A Volume Holographic Grating Triplexer (VHGT) is an optical element that diffracts the 1550nm and 1490nm signals into separate directions while transmitting the 1310nm upstream signal.
Compared to thin film interference filter, the VHGT enables the 1310nm transmitter laser (TX) and the receivers (RX) to be on the same side, either on the same plane or at different heights, thus enabling low cost packaging.
