DS3-11444-K405EMSCN 405nm Semiconductor Laser System

激光二极管 — 尾纤辐射输出功率 Ppeak [极限值 / CQF938/400]: max:100 mW 激光二极管 — 反向电压 VR [极限值 / CQF938/400]: max:2.0 V 激光二极管 — 正向电流 IF [极限值 / CQF938/400]: max:600 mA

In modern hybrid fiber coax (HFC) and cable television (CATV) systems, 1550nm externally modulated laser sources are used for super trunking and distribution.Due to the availability of the erbium-doped fiber amplifier (EDFA), which allows re-amplification of the optical signal without conversion into radio frequency (RF), such systems are very flexible in providing custom-made solutions with good carrier-to-noise ratios (CNR). In short haul metro links, the high power of the JDSU CQF938 eliminates the need for additional amplifiers. The CQF938 high power 1550 nm continuous wave (CW) distributed feedback (DFB) laser is available in a standard 14-pin butterfly package equipped with a polarization maintaining fiber (PMF) to facilitate coupling to a modulator. It shows superb thermal stability, high side-mode suppression ratios (SMSR), very low relative intensity noise (RIN), and small linewidths. The modulation bandwidth is in excess of 1 GHz, and permits various techniques for stimulated Brillouin scattering (SBS) suppression. SBS is a detrimental effect that can occur at very high power levels into the fiber, and which leads to noise bursts.
