Fabless optical modem components maker Enablence Technologies Inc. is angling for up to $50 million in a public offering, its second financing effort in eight months. The Ottawa-based company says it will use the raised net proceeds for working capital and expansion of product lines, among other purposes. Led by Paradigm Capital Inc. and including Haywood Securities Inc., Raymond James Ltd. and Dundee Securities Corp., the offering is expected to close on or around Oct. 25. In March, Enablence raised gross proceeds of $15 million in a private placement.
