TRPA48L2MCWDM

Multi-rate OC-48/STM-16 LR-2/L-16.2 SFP CWDM Transceivers with Digital Diagnostics TRPA48L2M CWDM Product Description The TRPA48L2M CWDM SFP series of multi-rate fiber optic transceivers with digital diagnostics monitoring functionality provide a quick and reliable interface for long reach (LR-2) 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) LR-2/L-16.2 long 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. The higher optical link power budget of 28dB is to accommodate the wavelength multiplexing and de-multiplexing insertion losses. All transceivers are Class I Laser products per U.S. FDA/CDRH and international IEC-60825 standards. The TRPA48L2M 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 metal for EMI immunity.
