Installation
The ABCU-5700/5710RZ can be installed in or removed
from any MultiSource Agreement (MSA) compliant
Small Form Pluggable port whether the host equipment
is operating or not. The module is simply inserted, small
end first, under finger-pressure. Controlled hot-plugging
is ensured by design and by 3-stage pin sequencing at
the electrical interface to the host board. The module
housing makes initial contact with the host board EMI
shield, mitigating potential damage due to Electro-Static
Discharge (ESD). The module pins sequentially contact
the (1) Ground, (2) Power, and (3) Signal pins of the
host board surface mount connector. This printed circuit
board card-edge connector is depicted in Figure 2.

Serial Identification (EEPROM)
The ABCU-5700/5710RZ complies with an industry
standard MultiSource Agreement that defines the serial
identification protocol. This protocol uses the 2-wire serial
CMOS EEPROM protocol of the ATMEL AT24C01A or
equivalent. The contents of the ABCU-5700/5710RZ serial
ID memory are defined in Table 10 as specified in the SFP
MSA.
Controller and Data I/O
Data I/Os are designed to accept industry standard
differential signals. In order to reduce the number of
passive components required on the customer’s board,
Avago Technologies has included the functionality of the
transmitter bias resistors and coupling capacitors within
the module. The transceiver is compatible with an “ac-
coupled” configuration and is internally terminated. Figure
1 depicts the functional diagram of the ABCU-5700/
5710RZ. 100-ohm resistor shown at RX_LOS in Figure 1
refers to ABCU-5710RZ configuration, not ABCU-5700RZ
configuration.
Caution should be taken into account for the proper
interconnection between the supporting Physical Layer
integrated circuits and the ABCU-5700/5710RZ.
Figure 4 illustrates the recommended interface circuit.
Several control data signals and timing diagrams are
implemented in the module and are depicted in Figure 6.
