SFP CWDM Transceivers with Digital Diagnostics
TRPE48KE2 CWDM
Product Description
The TRPE48KE2 CWDM SFP series of multi-rate fiber optic transceivers
with digital diagnostics monitoring functionality provide a quick and
reliable interface for extended 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 extended
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 Fiber 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 32dB 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 TRPE48KE2 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 (Commercial
Temp.) or -5°C to +85°C (Extended Temp.). The housing is made of
metal for EMI immunity.
