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 reli-
able interface for long reach applications. Diagnostics monitoring func-
tionality (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 com-
patibility.
