Description
The 1.0625/2.125Gbps Small Form Factor (SFF-
PTH-SW/LW-2X5/2X6) is an integrated fiber optic
transceiver that provides a high-speed serial link at
a signaling rate up to 2.125Gb/s. The SFF-PTH-
SW/LW-2X5/2X6 conforms to the American National
Standards Institute’s (ANSI) Fibre Channel, FC-PI
specification for short and long wavelength opera-
tion (200-M5-SN-I, 200-M6-SN-I,100-M5-SN-I,100-
M6-SN-I, 200-SM-LC-L, and 100-SM-LC-L).
The transceiver is insensitive to the data rate of the
incoming electrical and optical signals. The trans-
ceiver complies with the 1.0625Gb/s Fibre Channel
specification and 2.125Gb/s FC Standard without an
external control signal.
The SFF-PTH-SW/LW-2X5/2X6 is ideally suited for
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 applica-
tions where high data rates are required. This speci-
fication applies to a pin through hole (PTH) module
which has a 2 by 5 electrical connector pin configu-
ration.
The SFF-PTH-2125-SW uses a short wavelength
(850nm) VCSEL (Vertical Cavity Surface Emitting
Laser) source. This enables low cost data transmis-
sion over optical fibers at distances up to 500m at
1.0625Gb/s and 300m at 2.125Gb/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-PTH-LW uses a long wavelength
(1310nm) edge emitting laser. This enables data
transmission over optical fibers at distances up to
10,000 m on a single mode (9/125µm) optical fiber.
Encoded (8B/10B) [3], [4], gigabit/sec serial differen-
tial PECL signals traverse a PTH connector interfac-
ing the SFF-PTH-SW/LW-2X5/2X6 to the host card.
The 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 one, amplified
and delivered to the host card. This module is
designed to work with industry standard “10b” Seri-
alizer/Deserializer modules.
The SFF-PTH-SW/LW-2X5/2X6 is a Class 1 laser
safe product. The optical power levels, under normal
operation, are at eye safe levels. Optical fiber cables
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 8 and Control
Electrical Interface on page 9.
Rx_DAT
The incoming optical signal is converted and repowered as a differential PECL serial data stream. The
Receive Signal Interface table on page 8 gives the voltage levels and timing characteristics for the Rx_DAT
signals.
Rx_SD
The Receive Signal Detect line is high (a logical one) when the incoming modulated light intensity is sufficient
for reliable operation. This is the state for normal operation. The line is low (a logical zero) when incoming
modulated light intensity is the 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 diagnostic purposes.
This signal has a push-pull output driver.
Tx_Fault (Only available on 2 X 6)
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.
