Multi-rate Gigabit Ethernet & Fibre Channel
SFP Transceivers with Digital DiaGnostics
TRPEG1-E2 Single Mode
Produ c t D es c rip tion
The TRPEG 1-E2 SFP series of multi-rate fiber optic transceivers w ith
integrated digital diagnostics monitoring functionality provide a quick
and reliable interface for 1000BA SE-LX G igabit Ethernet and 1.062G Bd
Fibre Channel applications. The transceivers are designed to support
data rates ranging from 1.25G b/s dow n to 125M b/s. The diagnostic
functions,alarm and w arning features as described in the M ulti-Source
A greement (M SA )document,SFF-8472 (Rev. 9.4),are provided via an I²C
serial interface.
Four options are offered w ith minimum optical linkpow er budgets of11dB,
18dB,22dB and 24dB to support 10km to 80km link applications. Option
“LX”uses a 1310nm Fabry Perot laser and provides a minimum optical
link budget of 11dB, corresponding to a minimum distance of 10km,
assuming fiber loss of0.45dB/km. Option “EX”uses a 1310nm D FB laser
and provides a minimum optical link budget of18dB,corresponding to
a minimum distance of40km,assuming fiber loss of0.35dB/km. Options
“YX”and “ZX”use 1550nm D FB lasers and provide a minimum optical link
budgets of22dB and 24dB respectively,w hich correspond to minimum
distances of 70km and 80km, assuming fiber loss of 0.25dB/km. A ll
modules satisfy Class I Laser Safety requirements in accordance w ith the
U .S. FD A /CD RH and international IEC-60825 standards.
The transceivers connect to standard 20-pad SFP connectors for hot plug
capability. This allow s the system designer to make configuration changes
or maintenance by simply plugging in different types of transceivers
w ithout removing the pow er supply from the host system.
The transceivers have colored bail-type latches,w hich offer an easy and
convenient w ay to release the modules. The latch is compliant w ith the
SFP M SA .
The transmitter and receiver D ATA interfaces are AC-coupled internally.
LV-TTL Transmitter D isable control input and Loss of Signal output
interfaces are also provided.
The transceivers operate from a single +3.3V pow er supply over operating
case temperature ranges of-5°C to +70°C or -40°C to +85°C. The housing
is made ofmetal for EM I immunity.
