Fibertsore Launched DFB(distributed feedback) Laser Module

Fibertsore Launched DFB(distributed feedback) Laser Module

By FS.COMApril 8, 2015

Apr. 10th, Shenzhen, FS.COM News – FS.COM introduced new DFB(distributed feedback) laser modules for LAN, WAN, CATV and long distance DWDM transmission systems applications.

This week, FS.COM launched new DFB laser modules. DFB laser modules, also called DFB butterfly laser modules depending on their 14-pin shapes, are specialized for adopting the high-quality MQW-DFB chip to meet the requirement of a high-speed, specific-wavelength light transmission system. It can be used for continuous-wave and pulsed applications such as sensing, frequency doubling, light detection & ranging, and injection seeding for fiber amplifiers or lasers. These products have a wide range of applications in the LAN, WAN, MAN and CATV transmission system, as well as long distance DMDW transmission system. In addition, they can be used in the stabilized light source, modulated light source, or other communication equipment such as the CATV transmitter.

These DFB butterfly laser modules are constructed of hermetically sealed 14 pin butterfly package, a built-in optical isolator, a monitor photodiode, a thermoelectric cooler, single mode pigtails and FC/APC connector. In general, DFB laser modules with different wavelengths are used for different applications. At present, FS.COM offers DFB laser modules with there types of wavelengths, i.e. 1310 nm, 1550 nm and 1490nm. In general, a 1310nm DFB laser module is used for CATV applications while 1490nm or 1550nm DFB laser modules are mostly used for DWDM applications. The 1310nm DFB laser module also delivers superior linearity and supports fiber lengths up to 10 km without dispersion issues. And 1550nm C-Band DWDM laser module features low adiabatic chirp to maximize signal quality over both short and long fiber lengths. The laser's superior linearity minimizes degradation of the broadcast signals caused by distortions and non-linear effects. Additionally, In order to enhance the application situation, several options for Output Power, such as 5, 10, 15, 16, 20, 24, 30 mW are available with us.
