3.4 CPRI Fiber Optic Cable
CPRI fiber optic cables are classified into multimode fiber optic cables and single-mode fiber
optic cables. They transmit CPRI signals.
The maximum length of a multimode fiber optic cable connecting a BBU and an AAU is 150
m (492.12 ft).
A single-mode fiber optic cable consists of a single-mode pigtail and a trunk single-mode fiber
optic cable, which are connected through an optical distribution frame (ODF). The maximum
length of the single-mode pigtail on the BBU side is 20 m (65.62 ft), and the maximum length
of the single-mode pigtail on the AAU side is 70 m (229.66 ft).
NOTE
l
The ODF and trunk single-mode fiber optic cable are provided by the customer and must comply with
the ITU-T G.652 standard.
l
The ODF is an outdoor transfer box for fiber optic cables, which interconnects the single-mode pigtail
and trunk single-mode fiber optic cable.
l
A multimode fiber optic cable and a single-mode fiber optic cable are connected to a multimode optical
module and a single-mode optical module, respectively.
