10G / 40G / 100G optical fiber link test technology

In this era of information industrialization, whether it's the use of emerging technologies or the construction of smart cities, the application is definitely inseparable from the essential network. The construction of the basic network is principally based on the website, active terminals and interconnection gear, and the essential interconnection channel-wiring system for the construction of the network. The wiring system must be installed and installed on site.It is vunerable to factors like the environment, product quality, and installation process. It's the most essential link in identifying the standard of network transmission. The reliability of the wiring system depends not merely on the product quality supervision in the project.But it addittionally on the ultimate check and on-site acceptance testing. Now introduces you to the optical fiber link test.

10G fiber link test

The MPO connector can support at least 12-core optical fiber, and the MPO connector is mainly used for pre-connected optical cables. Because there are 12-core channels for MPO fiber, for duplex transmission, there are mainly three types of connection ways of A, B, and C (MPO fiber link polarity. The three methods are for the transmission end to connect to the reception end. The compatibility and consistency of the links. In the 10G Fibre Channel, the polarity of the MPO backbone link is principally in the sort B mode. Both ends are changed into the LC interface through the MPO to LC transceiver box, and then connected to these devices through the LC jumper. This example is mainly found in high-density wiring systems in data centers.

Link under test:

1 MPO-MPO fiber jumper, with MPO-LC transceiver backbone links at both ends
Step:

1) Place the benchmark:

Two FC-LC test jumpers connect the light source and optical power meter.

2) Disconnect the jumper and the adapter

3) Connect the optical fiber under test (MPO-LC transceiver box at both ends, MPO-MPO pre-connected optical cable in the centre), and connect the LC test jumper to both ports of the transceiver at both ends.

4) Record and save losing value of the existing tested fiber channel, and replace the source of light end LC jumper to the transceiver 2-12 port record and save before loss test of 12 channels is completed.

400G / 100G MPO fiber link test

A typical MPO / MTP link is composed of two MPO jumpers at both ends, two MPO adapters and MPO's pre-connected backbone optical cable. In TIA- 568-C.0-2009B.4, for parallel multi-channel transmission, A and B receive.

To be able to make sure the compatibility and unity of the link, construction and maintenance are far more convenient, especially MPO patch cords that are frequently plugged and replaced. In the 40G / 100G wiring system, Mode B is additionally used. The amount of channels of 40G and 100G are different, however the transmission link model may be the same, both make use of MPO / MTP interface for end-to-end transmission. Therefore, we consider 40G single- channel transmission for example. When testing, we have to focus on the types of ports that are pre-connected with optical cables and jumpers-with and without guide pins (male).

The next is the most typical MPO fiber link model without guide pin (female) at both ends.

Tools: MPO light source and MPO optical power meter (MPO dedicated test source of light and optical power meter, the instrument's MPO port contains 12 light source outlets and optical power meter inlets).

1) Set the benchmark:

Use MPO-MPO (male-male) jumper to short-circuit the MPO source of light and MPO optical power meter, first choose the polarity corresponding to the jumper on the instrument, and then press the reference value (setting reference) setting button, then your optical power meter Record the original optical power value received.

2) Join MPO-MPO (male-male)

Keep carefully the jumper connection at the light source end unchanged, just unplug the jumper plug of the optical power meter, and add an MPO-MPO (male-male) test jumper of qualified quality and correct polarity to the optical power meter (ought to be beforehand Test passed).

3) Test

Place the instrument on the primary test interface, insert the test jumpers on the source of light and the optical power meter in to the two ends of the link under test, press the test button, and the instrument gives a pass / fail result (or provide a similar prompt after a couple of seconds) (Picture), press the storage button, name and conserve the test outcomes. Continue steadily to test another MPO fiber.
Because fiber links have great advantages in meeting people's demand for high bandwidth, the usage of optical fibers is becomer wider. Whether wiring construction personnel or network maintenance personnel.It's important to master the abilities of fiber link testing.Read more:https://www.oemfibers.com
