FAMC-GDSR3S2-20 , 1000M Cascade Fiber Optic Media Converter Optical Ethernet Switch With 3 RJ45 Ports

How much attenuation can't be loaded by Gigabit fiber media converter? -28 dbm.

Attenuation is closely related to ACR, and small attenuation will contribute to the improvement of ACR. The attenuation of the cable depends on many factors like structure, length and environmental temperature. How to reduce the attenuation of the fiber optic media converter? There are several measures to reduce the attenuation:

A) the total length of the horizontal cable and the work area cable is not more than 100 meters. According to the attenuation formula, the longer the cable is, the greater the attenuation is.

B) do not lay long cables in the metal conduit and near the surface of any other conductor, it will reduce 2%/3% of additional attenuation. In addition, the high temperature will also seriously increase attenuation. Among all the characteristics of the cabling system, crosstalk has the biggest impact on the network performance, it affects the following parameters: NEXT, Power sum, ACR, etc., reducing crosstalk value is conducive to the improvement of the above parameters.

Specific measures to reduce crosstalk are:

A) In wire pairing connection, it should be in accordance with the TIA - 568B standard to connect, otherwise, string connection will produce serious crosstalk. If NEXT can not pass the test, not only that, a series of parameters related to NEXT, such as ACR, will also be unable to pass the test because of wires pairing, that is to say, the original high quality of the cable will become very poor performance due to string connection.

B) when the cable is apart to connect or install to the patch panel or frame, make the non twisted part as short as possible, the longest is no more than 13mm.

In addition, besides the above-mentioned methods, when install the cable, the cable shall be treated carefully without too much force, bending radius of the cable shall comply with the provisions of the index of the cable manufacturer, it is the only way to maintain the structure of the cable, which contributes to the improvement of technical indicators. This is also the basic requirements for construction.
