TOSA

Product overview

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℃。

Key features

  • Up to 16 channels at 100 GHz spacing or up to 32 channels at 50GHz spacing
  • C- or L-band
  • Simple tuning algorithm
  • 2.5 -10 Gbps direct modulation
