The customer should consider the cost performance of china laser pointer

It brings together the different wavelengths of light signals (wave) to an optical fiber transmission to the receiving end, again by the multiplexed optical signal to the optical fiber transmission separation (partial wave) out. Can be divided into branches mirror type, according to the spectrophotometric principle, WDM interference model and the diffraction grating are three products on the market most of the diffraction grating. The main indicators of the WDM insertion loss, crosstalk loss, wavelength interval and mpx. The insertion loss of the use of WDM and optical power loss is generally about-5dB. Crosstalk loss represents the WDM separated on the wavelength. The bigger the better, should be greater than 20dB crosstalk attenuation. The manufacturer can producechina laser pointer for the customer.
Since the cable length per disk mostly 5KM below, so in the long-distance fiber optic cables need to connect fiber optic cable in order to ensure the connection strength and used in a variety of environmental conditions, should be mounted connector box. Optical connector box to seal and waterproof, it can be cross-mounted, and can also be vertical installation. In order to ensure the connection strength, first with a connect fiber optic cable between the steel wire reinforcement, and then each weld good fiber flapper arranged hierarchically. The output of a fiber optic cable, 1 * 1 connector box, if it is a fiber optic input, N-root of the fiber optic cable output, select 1 * N connector box. Is the number of fibers cable when the cable core over 16 pairs, ordering, so that the internal increase the fiber heat-shrinkable tubing and fiber pallet. china laser pointer will be produced according to the specific requirements of the customer.
When more than 16 core fiber optic cable into the interior, and assigned to different devices mounted light wiring box light wiring box on the active joints, flanges, optical splitter, both fixed fiber optic cable, but also for the light equipment matching. 16 core cable into the interior and assigned to different devices can be installed optical terminal box, optical terminal box at one end and outdoor fiber optic cable to connect the other end of the separation of a number of root pigtail connected to the optical equipment. Used in the CATV optical network system is closely related to the quality and stability of a large number of passive devices, optical systems and optical passive devices, active devices using well-known brands in the world, and passive components do not carefully choose will resulting in poor quality system. And at the same time, the customer can ask the manufacturer to producechina laser pointerwith the material they want or need.
Speaking in front of the principle and characteristics of a variety of different lasers, in fact, to be made a practical semiconductor laser is first necessary to die welding on a heat sink, heat sink is gold-plated copper block, the main role is to enhance the cooling, if the laser cooling efficiency can not be continuous generation of laser, in addition to the laser tube core, but also a series of subsidiary function devices and good packaging. CATV optical transmitter laser is a laser chip, optical isolators, pigtail, thermoelectric cooling, thermal resistance, a photodetector, where the most appropriate name should be referred to as laser components should not be called lasers, laser components of the chart as shown below. Especially, the customer should consider the cost performance of china laser pointer.
The following are examples of laser components Laser Module 14PIN butterfly shell and tube metal package, the internal integration of light at 1310 nm directly modulated DFB laser chip thermistor cooling, backlight detectors and optical isolator its block diagram and pin functions are as follows: In fact, the above example, the structure of the laser assembly is a universal structure, laser whether domestic or imported laser, pin function and the above structure is consistent, that is, that all components of the laser can replace each other without changing the circuit structure of the optical transmitter. Part of the principle characteristics of a deep understanding of laser components, described in detail below it. And at the same time, the lower the price of green laser pointer is, the higher the cost performance of the laser pointer is.
