Description
The 1.0625/2.125 Gbps Small Form Factor (SFFPTH-SW-2X5/2X6) is an integrated fiber optic transceiver that provides a high-speed serial link at a signaling rate up to 2.125 Gb/s. The SFF-PTH-SW2X5/2X6 conforms to the American National Standards Institute’s (ANSI) Fibre Channel, FC-PI specification for short wavelength operation (200-M5-SNI, 200-M6-SN-I,100-M5-SN-I, and 100-M6-SN-I).
The transceiver is insensitive to the data rate of the
incoming electrical and optical signals. The transceiver complies with the 1.0625 Gb/s and 2.125
Gb/s Fibre Channel Standard without an external
control signal.
The SFF-PTH-SW-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 applications where high data rates are required. This specification applies to a pin through hole (PTH) module
which has a 2 by 5 or 2 by 6 electrical connector pin
configuration.
The SFF-PTH-2125-SW uses a short wavelength
(850nm) VCSEL (Vertical Cavity Surface Emitting
03/06/02
Laser) source. This enables low cost data transmission over optical fibers at distances up to 500m at
1.0625 Gb/s and 300 m at 2.125 Gb/s. A 50/125 µm
multimode optical fiber, terminated with an industry
standard LC connector, is the preferred medium. (A
62.5/125 µm multimode fiber can be substituted with
shorter maximum link distances.)
Encoded (8B/10B) [3], [4], gigabit/sec serial differential PECL signals traverse a PTH connector interfacing the SFF-PTH-SW-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 photoreceiver 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” Serializer/Deserializer modules.
The SFF-PTH-SW-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 shutting
off the laser transmitter.

Laser Safety Compliance Requirements
The SFF-PTH-SW-2X5/2X6 is designed and certified as a Class 1 laser product. If the power supply
voltage exceeds 5.0 volts, the transceiver may no
longer remain a Class 1 product. The system using
the SFF-PTH-SW-2X5/2X6 must provide power supply over voltage protection that guarantees the supply does not exceed 5.0 volts under all fault
conditions. If the voltage exceeds 4.0 volts, the reliability of the part may be compromised.
Caution: Operating the power supply above 5.0
volts or otherwise operating the SFF-PTH-SW2X5/2X6 in a manner inconsistent with its design
and function may result in hazardous radiation exposure, and may be considered an act of modifying or
new manufacturing of a laser product under US reg-
Page 2 of 22
ulations contained in 21 CFR(J) or CENELEC regulations contained in EN 60825. The person(s)
performing such an act is required by law to recertify
and reidentify the product in accordance with the
provisions of 21 CFR(J) for distribution within the
United States, and in accordance with provisions of
CENELEC EN 60825 (or successive regulations) for
distribution within the CENELEC countries or countries using the IEC 825 standard.
ESD Notice
It is advised that normal static precautions be taken
in the handling and assembly of the SFF-PTH-SW2X5/2X6 to prevent damage and/or degradation
which may be introduced by electrostatic discharge.

Transmit Section
The input, an AC coupled differential data stream from the host, enters the AC Modulation section of the laser
driver circuitry where it modulates the output optical intensity of a semiconductor laser. The DC Drive maintains the laser at the correct preset power level. In addition, safety circuits in the DC Drive will shut off the
laser if a fault is detected. The transceiver provides the AC coupling for the +Tx/-Tx lines. No AC coupling
capacitors are required on the host card for proper operation.
Receive Section
The incoming modulated optical signal is converted to an electrical signal by the photoreceiver. This electrical
signal is then amplified and converted to a differential serial output data stream and delivered to the host. A
transition detector detects sufficient AC level of modulated light entering the photoreceiver. This signal is provided to the host as a signal detect status line. The transceiver provides the AC coupling for the +Rx/-Rx
lines. No AC coupling capacitors are required on the host card for proper operation.

Input Signal Definitions
Levels for the signals described in this section are listed in Transmit Signal Interface on page 8 and Control
Electrical Interface on page 9.
Tx_DAT
A differential PECL serial data stream is presented to the SFF-PTH-SW-2X5/2X6 for transmission onto an
optical fiber by modulating the optical output intensity of the laser.
Tx_Disable
When high (a logical one), the Tx_Disable signal turns off the power to both the AC and DC laser driver circuits. It will also reset a laser fault if one should happen. When low (a logical zero), the laser will be turned on
within 1 ms if a hard fault is not detected. The transceiver contains a pull-down resistor to enable the laser
when the line is not connected on the host side. If driven, this line should be connected to a push-pull output
driver.

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.

Resetting a Laser Fault
Resetting a laser fault by toggling the Tx_Disable input will permit the SFF-PTH-SW-2X5/2X6 to attempt to
power on the laser following a fault condition. Continuous resetting and re-powering of the laser under a hard
fault condition could cause a series of optical pulses with sufficient energy to violate laser safety standards.
To alleviate the possibility of violating laser safety standards, the SFF-PTH-SW-2X5/2X6 will turn off the laser
if a second fault is detected within 25 ms of the laser powering on. This lock is cleared during each power on
cycle. Please refer to the timing diagrams below.

1. The minimum and maximum values of the average received power in dBm give the input power range to maintain a
BER < 10-12 when the data is sampled in the center of the receiver eye. These values take into account power penalties caused by
the use of a laser transmitter with a worst-case combination of spectral width, extinction ratio and pulse shape characteristics.
2. Optical Modulation Amplitude (OMA) is defined as the difference in optical power between a logic level one and a logic level zero.
The Optical Modulation Amplitude is defined in terms of average optical power (P AVG in µW) and extinction ratio (ER) as given by
OMA=2PAVG((ER-1)/(ER+1)). The extinction ratio, defined as the ratio of the average optical power (in µW) in a logic level one to
the average optical power in a logic level zero measured under fully modulated conditions in the presence of worst case reflections, must be the absolute (unitless linear) ratio and not expressed in dB.The specified Optical Modulation Amplitude at 2.125Gb/s
is equivalent to an average power of -15 dBm at an extinction ratio of 9 dB. At 1.0625Gb/s, the specified OMA is equivalent to an
average power of -17 dBm at an ER of 9 dB.
3. The Rx_SD has hysteresis to minimize “chatter” on the output line. In principle, hysteresis alone does not guarantee chatter-free
operation. The SFF-PTH-SW-2X5/2X6, however, presents an Rx_SD line without chatter, where chatter is defined as a transient
response having a voltage level of greater than 0.5 volts (in the case of going from the negate level to the assert level) and of any
duration that can be sensed by the host logic.

1. Launched optical power is measured at the end of a two meter section of a 50/125µm fiber (N.A.=0.20). The maximum and minimum of the allowed range of average transmitter power coupled into the fiber are worst case values to account for manufacturing
variances, drift due to temperature variations, and aging effects. The minimum launched optical power specified assumes an infinite extinction ratio at the minimum specified OMA.
2. Optical transition time is the time interval required for the rising or falling edge of an optical pulse to transition between the 20% and
80% amplitudes relative to the logical 1 and 0 levels. This is measured through a 4th order Bessel -Thompson filter with 0.75 *
Data Rate 3-dB bandwidth and corrected to the full bandwidth value.
3. Optical Modulation Amplitude (OMA) is defined as the difference in optical power between a logic level one and a logic level zero.
The Optical Modulation Amplitude is defined in terms of average optical power (PAVG in µW) and extinction ratio (ER) as given by
OMA=2PAVG((ER-1)/(ER+1)). In this expression, the extinction ratio, the ratio of the average optical power (in µW) in a logic level
one to the average optical power in a logic level zero measured under fully modulated conditions in the presence of worst case
reflections, must be the absolute (unitless linear) ratio and not expressed in dB. The specified Optical Modulation Amplitude is
equivalent to an average power of -9 dBm at an extinction ratio of 9 dB.
4. RIN 12 is the laser noise, integrated over a specified bandwidth, measured relative to average optical power with 12dB return loss.
See ANSI Fibre Channel Specification Annex A.
5. Eye opening is the portion of the bit time where the bit error rate (BER) ≤ 10-12. 1.0625Gb/s values meet the criteria listed in Ref
[1].
6. Deterministic Jitter is measured as the peak-to-peak timing variation of the 50% optical signal crossings when transmitting repetitive K28.5 characters. It is defined in FC-PH, version 4.3, clause 3.1.87 as:
Timing distortions caused by normal circuit effects in the transmission system. Deterministic jitter is often subdivided into
duty cycle distortion (DCD) caused by propagation differences between the two transitions of a signal and data dependent jitter (DDJ) caused by the interaction of the limited bandwidth of the transmission system components and the symbol sequence. 1.0625Gb/s values meet the criteria listed in Ref [1].
7. Coupled Power Ratio is the ratio of the average power coupled into a multimode fiber to the average power coupled into a single
mode fiber. This measurement is defined in EIA/TIA-526-14A.

Soldering Information
The SFF transceiver comes with a process/dust plug. When the plug is in place the transceiver can withstand
normal wave soldering and aqueous spray cleaning processes. While the transceiver is able to withstand an
aqueous cleaning process, it is not hermetically sealed; it was not designed to be immersed in cleaning solvents. An opening in the back of the top lid is to allow compressed air to be blown into the module to aid in the
removal of trapped water. This process should be performed after aqueous cleaning with the plug still
inserted. If the plug was not contaminated during the wave soldering and aqueous spray cleaning process it
can be reused as a dust plug.
