OC-12/STM-4 SFP Multimode
Transceivers with Digital Diagnostics
TRPA12MM
Product Description
The TRPA12MM SFP fiber optic transceivers with integrated digital diag-
nostics monitoring functionality provide a quick and reliable interface for
OC-12/STM-4 multimode applications. The diagnostic monitoring func-
tions, alarm and warning features are provided via an I²C serial interface.
The transceivers are designed to be compatible with the ATM require-
ments at OC-12/STM-4 (622Mb/s) data rate.
The TRPA12MM transceivers connect to standard 20-pad SFP connectors
for hot plug capability. This allows the system designer to make configu-
ration changes or maintenance by simply plugging in different types of
transceivers without removing the power supply from the host system.
The transmitter design incorporates a highly reliable 1310nm LED and an
integrated 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 three
operating case temperature ranges of -5°C to +70°C (“B” option), -5°C to
+85°C (“E” option), or -40°C to +85°C (“A” option). The housing is made of
plastic and metal for EMI enhancement.
