Notes:
1. Above data are test results without connectors. The insertion loss of one pair of connector is less than 0.3 dB.
2. For high power operation, it is recommended that pigtails should NOT be terminated with fibre-optic connectors at the COM or 1064nm port.
3. These 635/1550nm and 635/1064nm fused WDM couplers are customizable and above specifications are subject to change without notice.
