In generic cabling, MTP / MPO components have strong flexibility, which can realize 72 core optical fiber cabling at most, and 12 core optical fiber distribution box is mainly used for 40G / 100G data center. In 40G data center, 12 core optical fiber distribution box can be used to connect 40G QSFP + SR4 optical module and 10G SFP+ SR optical module; In 100G data center, 12 core optical fiber distribution box can be used to connect 100G QSFP28 SR4 optical module and 25G SFP28 SR optical module.

What is a 12 core optical fiber distribution box?

12 core optical fiber distribution box is a modular pre terminated optical fiber distribution box. Its front end is equipped with 6 / 12 LC duplex adapter connectors or SC and other types of connectors, and its rear end is equipped with 1 MPO / MTP adapter connector. MPO / MTP to LC / SC branch optical fiber jumper is placed in the box. 12 core optical fiber distribution box is mainly used to realize the safe conversion between MPO / MTP connector and LC or SC connector. It is generally used for optical fiber backbone connection and distribution management in Internet Data Center (IDC), Main Distribution Area (MDA) or Equipment Distribution Area (EDA).

How to connect 12 core optical fiber distribution box with the 40G 100G optical module?

Since the interface type of 40G / 100G SR4 optical module is MPO, we only need to connect the 40G / 100G SR4 optical module with 12 core optical fiber distribution box with one MPO multimode jumper, then place four 12 core optical fiber distribution boxes in 1U optical fiber distribution box, and finally use LC optical fiber jumper to connect 12 core optical fiber distribution box or other equipment. (The connection diagram as below:)

The arrival of 40G / 100G network makes 12 core optical fiber distribution box more and more important in optical fibernetwork. Now it has become a necessity for high-density cabling environment such as telecom network, WDM application, data center cabling and so on.
