Functional Description

Receiver Section Design

The receiver section for the AFCT-5745Z contains an In-

GaAs/InP photo detector and a preampliﬁer mounted in an

optical subassembly. This optical subassembly is coupled

to a postampliﬁer/decision circuit on a circuit board. The

postampliﬁer is ac coupled to the preampliﬁer. The cou-

pling capacitors are chosen to pass the SONET/SDH test

TX_FAULT

The AFCT-5745Z modules feature a transmit fault control

signal output which when high indicates a laser transmit

fault has occurred and when low indicates normal laser

operation. A transmitter fault condition can be caused

by deviations from the recommended module operating

conditions or by violation of eye safety conditions. A fault

is cleared by cycling the TX_DISABLE control input.

ization of the module.

Loss of Signal

Digital Diagnostic Interface and Serial Identiﬁcation

(EEPROM)

The Loss of Signal (LOS) output indicates that the optical

input signal to the receiver does not meet the minimum

detectable level for compliant signals. When LOS is high it

indicates loss of signal. When LOS is low it indicates normal

operation. The Loss of Signal thresholds are set to indicate

a deﬁnite optical fault has occurred (eg., disconnected or

broken ﬁber connection to receiver, failed transmitter).

The AFCT-5745Z complies with both SFF-8074i (SFP) and

SFF-8472 (Digital Diagnostic SFP) speciﬁcations available

from the SFF Committee at http://www.sﬀcommittee.

to standard SFP functionality, enabling failure prediction,

fault islolation, and component monitoring capabilities.

serial interface. Standard SFP EEPROM bytes 0-255 are ad-

dressed per SFF-8074i at memory address 0xA0 (A0h). New

digital diagnostic information is accessed per SFF-8472 us-

ing EEPROM bytes 0-255 at memory address 0xA2 (A2h).

A schematic diagram for the transmitter is shown in Figure

1. The AFCT-5745NPZ incorporates a 1310nm DFB laser

as its optical source, the AFCT-5745UPZ incorporates a

1550nm DFB laser as its optical source. All part numbers

have been designed to be compliant with IEC 825 and

CDRH eye safety requirements. The optical output is

controlled by a custom IC that detects the laser output

via the monitor photodiode. This IC provides both dc and

ac current drive to the laser to ensure correct modulation,

eye diagram and extinction ratio over temperature, supply

voltage and operating life.

The AFCT-5745Z provides real time access to transceiver in-

ternal supply voltage and temperature, transmitter output

power, laser bias current and receiver average input power,

allowing a host to predict system compliance issues.

These 5 parameters are reported “internally” calibrated as

described in SFF-8472.
