Transceivers with Digital Diagnostics
TRPAFESM
Product Description
The TRPAFESM SFP series of fiber optic transceivers with integrated digital
diagnostics monitoring functionality provide a quick and reliable inter-
face for 100BASE-FX Fast Ethernet single mode applications. The diagnos-
tic functions, alarm and warning features as described in the Multi-Source
Agreement (MSA) document, SFF-8472 (Rev. 9.4), are provided via an I²C
serial interface.
The transmitter optical output power is compliant with ANSI X3.184-1993
standard for FDDI SMF-PMD category I. All modules satisfy Class I Laser
Safety requirements in accordance with the U.S. FDA/CDRH and interna-
tional IEC-60825 standards.
The transceivers connect to standard 20-pad SFP connectors for hot plug
capability. This allows the system designer to make configuration chang-
es or maintenance by simply plugging in different types of transceivers
without removing the power supply from the host system.
The transceivers have bail-type latches, which offer an easy and conve-
nient way to release the modules. The latch is compliant with the SFP
MSA.
The transmitter design incorporates a highly reliable 1310nm InGaAsP la-
ser and a driver circuit. The receiver features a transimpedance amplifier
IC for high sensitivity and wide dynamic range. The transmitter and re-
ceiver DATA interfaces are AC-coupled internally. LV-TTL Transmitter Dis-
able control input and Loss of Signal output interfaces are also provided.
The transceivers operate from a single +3.3V power supply over an op-
erating case temperature range of -5°C to +70°C (“B” option) or -40°C to
+85°C (“A” option). The housing is made of plastic and metal for EMI im-
munity.
