Description

Our tunable Laser had assembled with pigtail as Transmitter Optical Sub-Assembly (TOSA) , and which is based on an 8-pin TO-CAN package，that provide the competitive cost to customers. Our Tunable laser comprises a V-cavity edge-emitting tunable laser, a power monitoring photodiode, an isolator, and a TEC controller, with an LC connector. Currently it can provide up to 16 channels at 100GHz spacing or 32 channels at 50GHz spacing in C- or L- band (other wavelength bands available on request), with a customer specified starting wavelength. The laser chip can be operated in semi-cooled condition at 40-60℃ while the ambient operating temperature is between 0 and 70℃。
