Multi-rate OC-48/STM-16 LR-2/L-16.2 SFP DWDM Transceivers with Digital Diagnostics TRPW48L2/E2 DWDM Product Description The TRPW48L2/E2 DWDM SFP series of multi-rate fiber optic transceivers with digital diagnostics monitoring functionality provide a quick and reliable interface for long reach applications. Diagnostics monitoring functionality (alarm and warning features) is integrated into the design via an I2C serial interface per the Multi-Source Agreement (MSA) on DWDM SFP transceivers (Rev. 1.0, October 2005). Products under this series are compatible with SONET/SDH standards for OC-48/STM-16 (2.67Gb/s) Forward Error Correction and 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-SMLC-L (1.062Gb/s) applications per FC-PI standards. The transmitter incorporates a highly reliable 1550nm DFB laser with an operating wavelength in full compliance with 100GHz (0.8nm) spacing per ITU-grid. All transceivers are Class I Laser products per U.S. FDA/CDRH and international IEC-60825 standards. The TRPW48L2/E2 DWDM 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 blue 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 (Commercial) or -5°C to +85°C (Extended). The housing is made of metal designed for optimum thermal performance and electromagnetic compatibility.
