The package dimensions are Φ21xL60 mm for 532 nm, Φ21xL75 mm for 635, 650 nm, Φ24xL80 mm for 780, 850 nm, and Φ24xL95 mm for 980, 1030, 1060 nm.
Contact Ascentta with your custom configuration needs, specifying the port, wavelength, fiber type, cable type, fiber length, connector, maximum power, and package. For example, 'VCIR3=3-Port', '532=532nm', 'S=Single-Mode' for fiber type, etc. The given codes such as 'B=250um', 'L=900um' etc., should be used to specify cable type and other options.
