self-supervision functionality. The light that meets the point
sensor is captured and fed into a plastic optical fiber (POF). The
self-supervision functionality is achieved by an in-built
coupling between two fibers. AFBR-S10PS011Z is a miniature
connector used to connect a duplex POF cable to the point
sensor. The special POF-based sensor design allows the system
engineer to avoid any galvanic contact between the arc flash
area and the detection electronics.
Both AFBR-S10PS010Z and AFBR-S10PS011Z are part of the
Broadcom’s comprehensive arc flash detection portfolio. In
combination with Broadcom’s sensor transceiver
AFBR-S10TR001Z, they are intended to be used for the
detection of arc flash events in electrical power grids.

Data Sheet
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. Limits apply to each parameter in
isolation, all other parameters having values within the recommended operation conditions. It should not be assumed that limiting
values of more than one parameter can be applied to the products at the same time. Exposure to the absolute maximum ratings for
extended periods can adversely affect device reliability.

Notes
Storage and operating temperatures refer to the ranges over which the connectors can be used when not subjected to mechanical stress. Installation
temperature refers to the ranges over which connectors may be installed onto the fiber and over which connectors can be connected and disconnected from
the transceiver.

Notes
Valuesmeasured with 10 m of POF duplex cable (1.0-mm core diameter, 2.2-mm jacket diameter, NA 0.5).
Cp definition: The capturing properties of a point sensor are characterized by Cp, called "Capturing Constant" of the point sensor, which is defined as follows:
The optical power P at the photo detector can be calculated as P = Cp × E / K
P: Optical power on photo detector (W).
Cp: Capturing constant (m
2
)
E: Optical power density in illuminated area (W / m
2
), halogen lamp used as a light source.
K: Correction factor for transmission losses, calculated as: K = 10
(A × L2 / 10)
.
A: Fiber transmission loss 0.34 dB/m.
L2: Length of fiber between illuminated area and photo detector (m).
For heartbeat signal at 650 nm coupled from one fiber to the other fiber in a duplex cable.
