TRPE48KE2 CWDM

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

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.
