Product Description
The TRD148xL2/E2/X2-G DWDM SFP series of multi-rate fiber optic
transceivers with digital diagnostics monitoring functionality pro-
vide a quick and reliable interface for long reach applications. Diag-
nostics monitoring functionality (alarm and warning features) is inte-
grated into the design via an I²C serial interface per the Multi-Source
Agreement (MSA) on DWDM SFP transceivers.
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) applications, OC-3/STM-1 (156Mb/s) and OC-12/
STM-4 (622Mb/s) applications; Gigabit Ethernet LX (1.25Gb/s) appli-
cations 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) spac-
ing per ITU-grid. All transceivers are Class I Laser products per U.S.
FDA/CDRH and international IEC-60825 standards.
The TRD148xL2/E2/X2-G 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 internal-
ly. LV-TTL Transmitter Disable control input and Loss of Signal (LOS)
output interfaces are also provided. The transceiver operate from a
single +3.3V power supply over operating case temperature range
of -5°C to +70°C (Commerical), -5°C to +85°C (Extended) or -40°C to
+85°C (Industrial). The housing is made of metal designed for opti-
mum thermal performance and electromagnetic compatibility.
