How to distinguish the quality of MTP/MPO cable?

---

 

Generally,
if you want to buy high-quality MTP/MPO fiber optic patch cords, you need to consider
many factors, such as fiber core brand, connector, insertion loss, etc. The
following is a list of five characteristics that high-quality MTP/MPO wires
should have.

 

1.
Branded Fiber Optic Core

MTP/MPO
fiber optic patch cords are usually deployed in relatively small
spaces, such as telecommunications distribution boxes, data center cabinets,
etc. In these cases, the fiber core needs to have a curved arc. Inferior fiber
core bending usually results in loss of signal, resulting in interruption of transmission.
But brand optical fiber is different. For example, Corning optical fiber can
greatly improve bending performance, minimize signal loss, and achieve faster
and more efficient optical fiber wiring and installation. Therefore, brand
fiber cores are very important for MTP/MPO fiber jumpers.

 

2.
MTP/MPO connector that meets industry standards

MTP/MPO
fiber optic connectors can encapsulate 12, 24 or 72 fibers into one fiber to
increase fiber density, so it is very popular in data centers with limited space.
Industry-approved MTP/MPO connectors (such as US Conec or Senko connectors) can
ensure the polarity of MTP/MPO cables and reduce insertion loss and return
loss. The MTP/MPO connector conforming to industry standards is sturdy and
durable, and can be recycled hundreds of times. The interface between the
connector and the fiber jumper is round, so the fiber jumper can be carried out
from any direction of the MTP/MPO connector port Wiring simplifies the wiring
structure. Therefore, it is also very important to buy high-quality MTP/MPO
fiber optic patch cords and industry-approved MTP/MPO connectors.

 

3.
Insertion loss

Insert
Loss (Insert Loss) refers to the loss of the effective optical power of the
link caused by the insertion of a connector or plug. It is one of the key
factors affecting the performance of the optical fiber network. The smaller the
insertion loss, the better the network performance. In general, the insertion
loss of MTP/MPO multi-mode fiber patch cords should not exceed 0.6 dB, and the insertion
loss of single-mode MTP/MPO fiber patch cords should not exceed 0.75 dB. For
single-mode and multi-mode MTP/MPO fiber jumpers with low insertion loss (high
quality), the insertion loss is usually required to not exceed 0.35 dB. When
choosing MTP/MPO fiber optic patch cords, you can choose the supplier that
provides the insertion loss test report.

 

4.
Flame retardant grade

The
shell of MTP/MPO fiber jumper can be made of different materials, these
materials have different fire resistance, can be divided into polyethylene
(Polyethylene), polyvinyl chloride (PVC), low-smoke halogen-free (LSZH), etc.,
Most of them have good flame retardant properties. If there are higher
requirements for the installation environment, such as suspended ceilings and
raised floors, it is best to choose MTP/MPO fiber jumpers with a higher flame
retardant rating, so that it is not easy to burn or smoke in the event of a
fire.

 

When
purchasing MTP/MPO fiber optic patch cords, you can check the flame retardant
rating directly on the protective jacket, and then choose the appropriate
MTP/MPO fiber patch cord according to the actual applicable environment of the
protective jacket and flame retardant rating of the fiber optic patch cord. For
more information about the protective sleeve and flame retardant grade of
optical fiber jumper, please refer to the following: Optical fiber jumper

5.
Fiber patch cord test

MTP/MPO
fiber optic patch cord connector end face inspection: In order to ensure that
the fiber optic connector has qualified or higher performance, the
International Electrotechnical Commission (IEC) has developed the IEC
61300-3-35 standard to define whether the connector end face is qualified. The
end face of the MTP/MPO jumper connector is divided into four areas: core area,
cladding area, glue edge area and ferrule surface. It has requirements for
scratches and blemishes in each area of ​​the connection. Scratches represent
permanent linear surface features. Defects include all detectable non-linear
features on the fiber, including particles, other debris, pits, debris, edge
chipping, etc. The cleaner the end face, the better the cable quality.
Therefore, if you want to buy the best MTP/MPO cable, you should choose fiber
optic patch cords that pass end-face inspection, such as fast (FS) MTP/MPO
fiber optic patch cords.

 

If
the connector size of the MTP/MPO cable cannot meet the requirements, problems
such as system connection failure will occur. Therefore, it is very important
to choose MTP/MPO fiber patch cords that have passed the 3D interferometer
test.

 

 

 

In
summary, before buying MTP/MPO fiber optic patch cords, we need to consider
many factors. Nowadays, many suppliers can provide MTP/MPO fiber optic patch
cords, but not all patch cords are quality guaranteed. In order to choose
high-quality MTP/MPO fiber optic patch cords, please choose a MTP/MPO fiber
optic patch cord that can meet all the above standards.
