2.5 Gb/s CWDM SFP Transceiver (Multirate)
CT2 Series
Key Features
• SFP MSA compatible
• 2.5 Gb/s compliant CWDM performance for short haul
and long haul
• Microprocessor-based design fully implements the Digital
Diagnostic Monitoring Interface
• Automatic output power and extinction ratio control over
temperature and lifetime to compensate for laser efficiency
degradation
• Both PIN and APD versions meet -27 dB receiver reflectance
• Optical parameters tuned and optimized over temperature
in production test
Applications
The JDSU CT2 Series 2.5 Gb/s Coarse Wavelength Division Multiplexing
(CWDM) transceiver integrates optics and electronics in a Small Form Factor
Pluggable (SFP) package. It is Multisource Agreement (MSA) compatible and
designed for CWDM operation per ITU-T G.695 for unidirectional 8 channel
black-link transmission (S-C8S1-1DX and S-C8L1-1DX). Although optimized
for 2.5 Gb/s, the CT2 provides multi-rate capabilities and can be used for various
protocols ranging from OC-3 (155 Mb/s) up to 2.7 Gb/s including 622 Mb/s,
1x/2x FC, GbE and 2x GbE.
• Metro access
• Metro core
• Wide area networks
• Optical crossconnects
Compliance
The CT2 Series CWDM SFP transceiver provides a fully G.695 8 channel black-
link compliant interface between the optical Mux/Demux photonic layer and the
electrical layer. Its microprocessor-based modular design implements all features
specified in the SFP MSA compatible 2-wire Serial Digital Diagnostic Monitoring
Interface for Optical Transceivers.
• GR-253-CORE
• ITU-T G.957
• SFF-8472 Revision 9.3
• ITU-T G.695
The major components in this module include an uncooled distributed feedback
(DFB) based optical transmitter, a PIN or APD based optical receiver with
integrated transimpedence amplifier (TIA), an APD high voltage circuit (if
required), a microprocessor, a limiting post amplifier, and a laser driver. This
CWDM transceiver design offers a "hot-pluggable" interface and is available in
short haul (40 km, PIN) and long haul (80 km, APD) configurations.

Description
TD
TDb
Un-clocked, multirate, differential serial bit stream (155 Mb/s to 2.7 Gb/s) used to drive the optical transmitter.
Internally AC coupled and terminated via internal 100 Ω differential impedence.
RD
RDb
Rate_select
TxDIS
Differential received electrical signal capable of detecting 155 Mb/s to 2.7 Gb/s bit patterns.
The differential pair is internally biased and AC coupled. This signal requires 100 Ω external differential termination.
Internally monitored and available for future use. Can be customized for specific applications.
Transmitter Disable Input. A logic HIGH on this input pin disables the transmitter's laser so that there is no optical
output. If left open the transmitter will be disabled.
LOS
Loss of Signal (Open Collector). A logic HIGH on this output indicates an incoming signal level that is less than -25 dBm
but no greater than -31 dBm for the 40 km configuration and less than -34 dBm but no greater than -40 dBm for the
80 km configuration. LOS shall deassert (logic LOW) when a 3 dB (maximum), 0.5 dB (minimum) hysteresis is obtained.
Transmitter fault (Open collector). A logic HIGH indicates that the transmitter is in a fault condition.
MOD_DEF(0) is internally grounded to indicate the presence of the module. Must be pulled-up on host board with
10 KΩ resistor.

6. Formatted OC-48 pattern with scrambled PRBS 23 payload using Agilent Omni BER as the optical source driving an external OC-48 optical receiver with CDR. The
differential data outputs of this optical receiver with CDR. The differential dataoutputs of this optical receiver are used as the electrical inputs for the CT2 transmitter which
optically drives the Omni BER receiver input.
