It is W rod tW, strong and T. For long-distance transmission, even if a low-loss original fiber is used, the nine-wavelength at the receiving end will be small. The wave analogy is lo

At the end of the transmission source), it becomes a parallel beam of several grains of rice,
Light enters optical lens 1L+NB K (part B). Optical lens LN8 The source incident parallel to K is concentrated at the lens focal point at the opposite gA+1, or the core n section of the other source fiber OFF is placed at the 8mugi focal point at 11. It is synthesized into 1 and the core of 1P OPF is transmitted through the bamboo <, a also has a laser diode LDO
) It is impossible to obtain a light source whose output is approximately the initial number times the output of one light source. Note that when the output # of the laser diode LD is #-[, and a reflective film is provided on the end face of the multi-source fiber aopQ+cH+ (reduction ratio of 0.5 to 5), the output of the laser diode becomes a valley and returns to the diode (. The origin is a mixture of elements with different wavelengths in JM Genga's C = total angstroms,
When mode-locking occurs in a laser diode, laser oscillation always occurs.

With w = x, about xa, Atsumata sword 1 also has a core comrade, so the original weight 1C was small, but in the C part, the Wcv becomes large to 2a ~ loa, and the core comrades are falling. Unfortunately, the elements of each fiber are close together, and the core of each fiber is almost a heavy T (with the end of the eccentricity of the core being very close to each other. Therefore, when aligned by an optical lens,
Nines from each core can be combined equally with low loss.

With the core as the center 1ull, several fibers are taken as 1,
Unify the cladding by fusing the late X. (Part B in Fig. 1) When the gauze has been inserted, the cladding is stretched and the diameter of both the cladding and core is reduced by one diameter.
