This makes network testing a lot easier, especially when it comes to structured single-mode cabling in data centers, as well as the testing of MPO cables for FTTH/access networks and mobile phone front pods (FTTA/C-RAN).
Multipath push-on (MPO) connectors are used when many optical fibres have to be connected in very small spaces. An MPO connector usually contains twelve fibres. This not only saves space and weight but also saves installation time and costs.
