Product Details:
What is the optical fiber:
Optical fiber is the fiber that can transmit light, its main
function is to transmit light waves
2, the composition of the optical fiber:
The main component of communication fiber is high purity Shi Ying (
SiO 2 )
Transmission characteristics of optical fiber
1. attenuation of optical fiber
Optical signals travel in optical fibers, and as the distance increases, the energy becomes weaker and weaker. this is called fiber transmission attenuation.
2. dispersion of optical fiber
Different wavelengths of light or different modes of the same wavelength, in the optical fiber with different propagation speed caused by the time delay is different, resulting in interference, resulting in errors.
3. nonlinear effect of optical fiber
All the media are nonlinear, when the optical power increases to a certain extent, the nonlinear effect begins to appear, causing additional loss, crosstalk, etc

Transmission characteristics of optical fiber
1, according to the mode of optical fiber classification
Single - mode ( yellow ): light weight, wide transmission frequency bandwidth, large communication capacity, good confidentiality, no electromagnetic interference, small attenuation, large dispersion distribution, large effective area, short dispersion limited distance.
Multi - mode ( orange ): large attenuation, limited transmission bandwidth, large numerical aperture, high coupling efficiency, thick core, easy connection.

2, according to the form of connector is divided into:
FC-FC,FC-LC,LC-LC,FC-SC,SC-SC
3. according to end face form: PC, APC
Connection method of optical fiber connector
When connecting, ensure that the optical fiber of APC end face uses the optical fiber connector in the form of APC end face, i.e. the color corresponds to that of the optical fiber connector
Optical fiber appearance inspection
1,Optical fiber wire body:Appearance with the naked eye observation, uniform color, no layer feeling, no cracks, no indentation or scratch, no gap, pits or convex hull, no dirt, no surface die marks, not allowed to dye
2. PVC film covering:The surface of the PVC film covered by the optical fiber line shall not be damaged, dented, peeled, scratched, cracked and other bad phenomena.
3. connecting metal end:Optical fiber line and iron connection parts should be firmly bonded, adhesive can not have peeling or bubble bad phenomenon.
Metal port glue to highlight the metal upper edge, and the outer diameter of the glue can not exceed the metal outer diameter, height cannot exceed 1.0 mm.. The glue is required to be in a conical arc shape; The presence of glue is not allowed on the metal end outer surface of the pigtail.
4. connecting head:The ceramic ferrule head on the connector end is clean and dirty. Do not dope any other impurities as qualified. Connector white plastic parts can not have poor dyeing color.
Plastic parts can not have any burr and burr, shrink, fade, crack, uneven, dirt and other bad.
Method for clean end face of optical fiber
1, clean the front of the optical fiber wipe paper wipe clean
ceramic ferrule.
2, the optical fiber wipe paper level on the workbench, mat a few more below.
3, optical fiber wipe paper smooth side up.
4. hold the connector by hand so that the ceramic ferrule of the PC connector is perpendicular to the optical fiber wiping paper, and the APC connector needs to be wiped at an inclined angle of 8 degrees.
5, wipe the grain of the paper along the optical fiber
6, according to a single direction gently wipe 2 - 3 times, can't wipe back and forth, can't wipe the same position in the optical fiber wipe paper repeatedly
7, to check on the detector, until clean. This is the first time I've had a job.
8, pay attention to the light force when wiping. Scratch > = 1cm.
9, after cleaning, temporarily don't use the optical fiber need to jump wire dust cap wear well, jump wire winding is good, there is no winding, twisted phenomenon such as each other

Fiber performance determination method
when taking a new fiber, please use standard module to check the
power size, within the standard value + 0.3 DBM can be used.
Method for operate optical fiber product
Before each operation, check whether the tail fiber tray is neat,
if necessary to disk again. The correct disc placement requirements
are shown in the figure. note: the diameter of the disc after
placement is greater than or equal to 6 cm.
Wear a dust cap when the operation is complete.
Requirements for use of dust caps
A, confirm the use of dust cap must be clean, when using the dust
cap to check whether clean, no dust and foreign bodies, avoid
pollution. If yes, clean it before use.
B, when in use, will remove the dust cap in the specified clean material box. Always wear a dust cap after use.
C, optical fiber when not in use, must wear a dust cap.
D, optical fiber placement process, must first confirm the optical fiber ceramic core wear dust cap.
E, in the production process, pay attention to protect the dust cap or light mouth plug, such as dust cap / light mouth plug found abnormal damage, please replace the new dust cap / light mouth plug in time
F, wear dust cap or light plug in the whole production process / turnover process / aging / TC.
