Transceivers withDigital Diagnostics
TRPA12M CWDM
Product Description
TheTRPA12M CWDM SFP series of multi-rate transceivers with integrated digital
diagnostics monitoring functionality provide a quick and reliable interface
for long reach (LR) applications. The diagnostic functions, alarm and warning
features as described in the Multi-Source Agreement (MSA) document, SFF-
8472 (Rev. 9.3), are provided via an I²C serial interface.
Products under this series are compatible with SONET/SDH standards for OC-
12/STM-4 LR-2/L-4.2 and are capable of operating down to 155Mb/s data rate.
There are eight (8) wavelengths available: 1471nm, 1491nm, 1511nm, 1531nm,
1551nm, 1571nm, 1591nm and 1611nm. Two optical link power budgets are
available, 27dB and 29dB, providing an extra 2dB and 4dB over SONET/SDH
link budgets, respectively, to accommodate the wavelength multiplexing
and de-multiplexing insertion losses. All modules satisfy Class I Laser Safety
requirements in accordance with the U.S. and international standards as
described in the FDA/CDRH and IEC-60825 documents, respectively.
The TRPA12M CWDM multi-rate transceivers connect to standard 20-pad SFP
connectors for hot plug capability. This allows the system designer to make
configuration changes or maintenance by simply plugging in different types
of transceivers without removing the power supply from the host system.
The transceivers have colored bail-type latches, which offer an easy and
convenient way to release the modules. The latch is compliant with the SFP
MSA.
The transmitter and receiver DATA interfaces are AC-coupled internally. LV-TTL
Transmitter Disable control input and loss of Signal output interfaces are also
provided.
The transceivers operate from a single +3.3V power supply over an operating
case temperature range of -5°C to +70°C (“B” option) or -5°C to +85°C (“E”
option). The housing is made of plastic and metal for EMI immunity.
