Multi-rate OC-48/STM-16 IR-2/S-16.2 SFP
CWDM Transceivers with Digital Diagnostics
TRPA48I2M CWDM
Product Description
The TRPA48I2M CWDM SFP series of multi-rate fiber optic transceivers with digital
diagnostics monitoring functionality provide a quick and reliable interface for
intermediate reach (IR) applications. Diagnostics monitoring functionality (alarm
and warning features) is integrated into the design via an I²C serial interface per
the Multi-Source Agreement (MSA) SFF-8472, Rev. 9.4.
Products under this series are compatible with SONET/SDH standards for OC-
48/STM-16 (2.488Gb/s) IR-2/S-16.2 intermediate reach applications, OC-3/STM-1
(156Mb/s), and OC-12/STM-4 (622Mb/s) SR/I-1 and I-4 short reach applications;
Gigabit Ethernet LX (1.25Gb/s) applications per IEEE 802.3; and Fibre Channel
200-SM-LC-L (2.125Gb/s) and 100-SM-LC-L (1.062Gb/s) applications per FC-PI
standards. The transceivers support data rates ranging from 2.67Gb/s down to
125Mb/s, and are available in eight (8) wavelengths: 1471nm, 1491nm, 1511nm,
1531nm, 1551nm, 1571nm, 1591nm, and 1611nm. Two optical link budgets are
available, 17dB and 19dB, providing an extra 3dB and 5dB (compared to OC-48/
STM-16 IR-2/S-16.2), 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. FDA/CDRH and international IEC-60825
standards.
The TRPA48I2M CWDM 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 (LOS) 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.
