Question 1

Q:

What module should be used with the M4MPOA2x4F fiber patch cable?

Answer

A:

It is typically used for branching applications, connecting modules such as OSFP-800G-2xSR4H and four OSFP-400G-SR4H modules.

Question 2

Q:

Why is the polished type of multimode patch cable used in the NDR module MPO/APC (Angled Polished Connector)?

Answer

A:

High-speed products have significant losses, and the connector end face is usually polished with an APC angle of 8 degrees. This minimizes back reflections of light entering the laser source, reducing signal loss and improving overall transmission performance.

Question 3

Q:

Can an APC-terminated module be used with a UPC-terminated patch cable?

Answer

A:

It is not recommended to do so. APC and UPC connectors have different end face geometries (APC with an angled end face and UPC with a flat end face), making them incompatible for complete coupling. This mismatch can result in signal attenuation, distortion, and compromised signal transmission quality and stability along the entire link.

Question 4

Q:

What is the difference between the female and male connectors of MTP/MPO patch cords?

Answer

A:

Patch cord connectors can be either female or male, referring to the gender type of the connector. Male connectors have pins, while female connectors do not. When connecting two cables using an adapter, they must have opposite genders (one male and one female). When connecting with a module, a female connector is typically used.

Question 5

Q:

What is the difference between APC and UPC connectors in fiber patch cables?

Answer

A:

APC connectors have an 8-degree angled end face, which significantly reduces back reflections, minimizing signal distortion and improving transmission performance. They are commonly used in single-mode fiber links or with APC interface multimode modules for high-speed applications. UPC connectors have a flat end face angle and offer lower return loss compared to APC. They are commonly used in multimode fiber links.

Question 6

Q:

What is the difference between OM2, OM3, OM4, and OM5 patch cords?

Answer

A:

These four types of patch cords are all multimode fiber patch cords. OM2 has the lowest transmission rate and distance. OM3 offers improved transmission rates and distances and is commonly used for 10G/25G low-speed links. OM4 and OM5 fibers support longer transmission distances and are typically used for 40G/100G and higher-speed links, such as 200G/400G/800G.

Question 7

Q:

What should I consider when using patch cords?

Answer

A:

When using patch cords, ensure that they are compatible with the module and connector types. Avoid excessive bending or pulling. Regularly clean the patch cord end faces to prevent contamination and maintain signal transmission quality.
