This signal is an open collector output (pull-up required provides an AC-coupled, internally terminated data

for Low VCC. The transmitter fault condition can also

be monitored via the two-wire serial interface (address

A2h, byte 110, bit 2).

The AFCT-571xZ family complies with the SFF-8074i

speciﬁcation, which deﬁnes the module’s serial identiﬁ-

cation protocol to use the 2-wire serial CMOS EEPROM

protocol of the ATMEL AT24C01A or similar. Standard

deﬁned in SFF-8074i, the AFCT-5715Z is also compliant

to SFF-8472 (the digital diagnostic interface for SFP).

This enhancement adds digital diagnostic monitoring

Receiver Section

The receiver section for the AFCT-571xZ contains an

InGaAs/InP photo detector and a preampliﬁer mounted

in an optical subassembly. This optical subassembly is

coupled to a post ampliﬁer/decision circuit on a circuit

board. The design of the optical subassembly provides

to standard SFP functionality, enabling failure predic-

tion, fault isolation, and component monitoring capa-

bilities.

Using the 2-wire serial interface, the AFCT-5715Z

provides real time access to transceiver internal supply

voltage and temperature, transmitter output power,

laser bias current and receiver average input power,

allowing a host to predict system compliance issues.

These ﬁve parameters are internally calibrated, per the

MSA. New digital diagnostic information is accessed

per SFF-8472 using EEPROM bytes 0-255 at memory

address 0xA2 (A2h).

Connection to the receiver is provided via a LC optical

connector.

RX_LOS

The receiver section contains a loss of signal (RX_LOS)

circuit to indicate when the optical input signal power

is insuﬃcient for Gigabit Ethernet compliance. A high

signal indicates loss of modulated signal, indicating link

failure such as a broken ﬁber or a failed transmitter. RX_

LOS can be also be monitored via the two-wire serial

(address A2h, byte 110, bit 1).

The digital diagnostic interface also adds the ability to

disable the transmitter (TX_DISABLE), monitor for Trans-

mitter Faults (TX_FAULT) and monitor for Receiver Loss

of Signal (RX_LOS).

Contents of the MSA-compliant serial ID memory are

shown in Tables 10 through 14. The SFF-8074i and

SFF-8472 speciﬁcations are available from the SFF

Committee at http://www.sﬀcommittee.org.
