AFBR-5978Z
Digital Diagnostic 650nm Transceiver for Fast Ethernet
(10/100 Mbps) with SC-RJ connector
Data Sheet
www.DataSheet4U.com
Description
The AFBR-5978Z transceiver provides the system
designer with the ability to implement Fast Ethernet
(100 Mbps) or Ethernet (10 Mbps) over 50 meter
standard bandwidth 0.5±0.05 NA POF and 100 meter
standard bandwidth 0.37±0.04 NA HCS fiber. The
connectivity available for the transceiver is SC-RJ. This
product is lead free and compliant with RoHS.
Transmitter
The transmitter contains a 650nm LED with an
integrated driver. The LED driver operates at 3.3 V. It
receives a LVPECL compatible electrical input, and
converts it into a modulated current driving the LED.
The LED is packaged in an optical subassembly, part
of the transmitter section. The optical subassembly
couples the output optical power efficiently into POF
or HCS fiber.
Receiver
The receiver utilizes a Si PIN photodiode. The PIN
photodiode is packaged in an optical sub-assembly,
part of the receiver section. This optical subassembly
couples the optical power efficiently from POF or HCS
fiber to the receiving PIN. The integrated IC operates
at 3.3 V and converts the photocurrent into LVPECL
compatible electrical output.
Package
The transceiver package consist of four basic elements;
two optical subassemblies, an electrical subassembly
and the housing as illustrated in the block diagrams in
Figure 1. The package outline drawing and pin out are
shown in Figures 2 and 3.
Features
• Compatible with electrical and optical performance
of the POFAC recommendations for the Fast
Ethernet over Plastic Optical Fiber (POF).
• Compatible with the Electrical and Optical
performance of the ProfiNet recommendations the
Fast Ethernet over POF and Hard-Clad Silica Fiber
(HCS).
• Manufactured in an ISO 9001 certified facility
• DMI [Digital Diagnostics Monitoring Interface,
SFF-8472 Rev 9.3], provides real-time monitoring of:
- Temperature
- Supply voltage
- Received Optical Power (Alarm/Warning flag)
• LVPECL Signal Detect Output
• Temperature range –25 to +85 °C
Applications
• Factory automation at Fast Ethernet speeds
• Fast Ethernet networking over POF and HCS
• Link Distance up to 50 m POF or 100 m HCS
(See application note 5290 for details)

Digital Diagnostics Monitoring Interface
The AFBR-5978Z transceiver features an enhanced
digital diagnostic interface, compliant to the “Digital
Diagnostic Monitoring Interface for Optical
Transceivers” SFF-8472 Multi-source Agreement (MSA).
Please refer to the MSA document to access
information on the range of options, both hardware
and software, available to the host system for exploiting
the available digital diagnostic features.
The enhanced digital interface allows real-time access
to device operating parameters, and includes optional
digital features such as soft control and monitoring of
I/O signals. In addition, it fully incorporates the
functionality needed to implement digital alarms and
warnings, as defined by the SFF-8472 MSA. With the
digital diagnostic monitoring interface, the user has
capability of performing component monitoring, fault
isolation and failure prediction in their transceiver-
based applications.

The diagnostic monitoring interface (DMI) has two 256
byte memory maps in EEPROM which are accessible
over a two wire interface: the serial ID memory map at
address 1010000X (0xA0) and the digital diagnostic
memory map at address 1010001X (0xA2).
The serial ID memory map contains a serial
identification and vendor specific information and is
read only.
The digital diagnostic memory map contains device
operating parameters and alarm and warning flags. The
operating parameters are to be retrieved through a
sequential read command ensuring that the MSB and
LSB of each parameter are “coherent”. Furthermore, it
contains 120 bytes that can be written by the user as
well as a writable soft control byte.

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.
