| Polarization Maintaining Filter Wavelength Division Multiplexer | |||
| 1310/1550nm or 1480/1550nm | |||
| The polarization maintaining filter WDM series provide wavelength division multiplexing while maintaining signal polarization. PM FWDM is based on environmentally stable thin film filters technology and are characterized with high extinction ratio, low insertion loss, and high return loss. They are ideal for high speed WDM network systems. |
