A compact TFF-based tri-port device (IN/ADD/DROP) tailored for O-band (1260-1360nm) DWDM systems. Pre-configured with SC/APC or LC/UPC connectors or other specified connector typies, this O_Band DWMD device can be widely used in PON system, FTTx network, DWDM system and Add/drop channel applications. The device is available in two encapsulation types: stainsteel tube or glass tube.
