Description
The 1.0625/1.25Gbps Serial Optical Converter
(SFF-PGG-1063/1250-SW/LW) is an integrated
fiber optic transceiver that provides a high-speed
serial link at a signaling rate up to 1.25Gb/s. The
SFF-PGG-1063-SW/LW conforms to the American
National Standards Institute’s (ANSI) Fibre Channel,
FC-PI specification for short and long wavelength
operation (100-M5-SN-I,100-M6-SN-I, and 100-SM-
LC-L). The SFF-PGG-1250-SW conforms to IEEE
802.3z 1000Base-SX standard [3], and the SFF-
PGG-1250-LW conforms to IEEE 802.3z 1000Base-
LX standard [3].
The SFF-PGG-1063/1250-SW/LW is ideally suited
for Gigabit Ethernet, and Fibre Channel applications
which include point to point links as well as Fibre
Channel Arbitrated Loop (FC-AL). It can also be
used for other serial applications where high data
rates are required. This specification applies to a
hot-pluggable (PGG) module which has a 2 by 10
electrical surface mount connector assembly.
The SFF-PGG-1063/1250-SW/LW transceiver fea-
tures a Serial ID module. The Serial ID module can
store up to 128 bytes of vital product data.
The SFF-PGG-1063/1250-SW uses a short wave-
length (850nm) VCSEL (Vertical Cavity Surface
Emitting Laser) source. This enables low cost data
transmission over optical fibers at distances up to
500m at 1.0625Gb/s and 550m at 1.25Gb/s. A
50/125µm multimode optical fiber, terminated with
an industry standard LC connector, is the preferred
medium. (A 62.5/125µm multimode fiber can be
substituted with shorter maximum link distances.)
The SFF-PGG-1063/1250-LW uses a long wave-
length (1310nm) edge-emitting laser. This enables
data transmission at distances up to 10,000m on a
single mode (9/125µm) optical fiber.
Encoded (8B/10B) [4], [5], gigabit serial differential
PECL signals traverse the connector interfacing the
SFF-PGG-1063/1250-SW/LW to the host card. The
incoming serial data modulates the laser and is sent
out over the outgoing fiber of a duplex cable.
Incoming modulated light is detected by a photore-
ceiver mounted in the LC receptacle. The optical
signal is converted to an electrical signal, amplified
and delivered to the host card. This module is
designed to work with industry standard “10b” Seri-
alizer/Deserializer modules.
The SFF-PGG-1063/1250-SW/LW is a Class 1 laser
safe product. The optical power levels under normal
operation are at eye safe levels, and optical fiber
can be connected and disconnected without shut-
ting off the laser transmitter.

Output Signal Definitions
Levels for the signals described in this section are listed in Receive Signal Interface on page 11 and Control
Electrical Interface on page 12.
Rx_DAT
The incoming optical signal is converted and repowered as a differential PECL serial data stream. The
Receive Signal Interface table on page 11 gives the voltage levels and timing characteristics for the Rx_DAT
signals.
Rx_LOS
The Receive Loss of Signal line is high (a logical one) when the incoming modulated light intensity is below
that required to guarantee the correct operation of the link. Normally, this only occurs when either the link is
unplugged or the companion transceiver is turned off. This signal is normally used by the system for diagnos-
tic purposes.
This signal has an open drain TTL driver. A pull up resistor is required on the host side of the SFF connector.
The recommended value for this resistor is 10 kΩ.
Tx_Fault
Upon sensing an improper power level in the laser driver, the SFF sets this signal high and turns off the laser.
The Tx_Fault signal can be reset with the Tx_Disable line.
The laser is turned off within 100 µs as shown in the Transmitter Fault Detection timing diagram below.
This signal has an open drain TTL driver. A pull up resistor is required on the host side of the SFF connector.
The recommended value for this resistor is 10 kΩ.
