Description
The 1.0625/1.25 Gb/s 1X9 Transceiver (1X9-
1063/1250-SW) is an integrated fiber optic trans-
ceiver that provides a high-speed serial link at a sig-
naling rate up to 1.25 Gb/s. The 1X9-1063-SW
conforms to the American National Standards Insti-
tute’s (ANSI) Fibre Channel, FC-PI specification for
short wavelength operation (100-M5-SN-I and 100-
M6-SN-I). The 1X9-1250-SW conforms to IEEE
802.3z 1000Base-SX standard [3].
The 1X9-1063/1250-SW 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.
The1X9-1063/1250-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 500 m at
1.0625 Gb/s and 550 m at 1.25 Gb/s. A 50/125 µm
multimode optical fiber, terminated with an industry
standard SC connector, is the preferred medium. (A
62.5/125 µm multimode fiber can be substituted with
shorter maximum link distances.)
Encoded (8B/10B) [4], [5], gigabit serial differential
PECL signals traverse a PTH connector interfacing
the 1X9-1063/1250-SW to the host card. The incom-
ing 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 SC 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 1X9-1063/1250-SW 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.

Gigabit Ethernet/Fibre Channel 1X9 Transceiver
Input Signal Definitions
Levels for the signals described in this section are listed in Transmit Signal Interface on page 6 and Control
Electrical Interface on page 7.
Tx_DAT
A differential PECL serial data stream is presented to the 1X9-1063/1250-SW for transmission onto an optical
fiber by modulating the optical output intensity of the laser. The transceiver provides the AC coupling for the
+Tx/-Tx lines.
Output Signal Definitions
Levels for the signals described in this section are listed in Receive Signal Interface on page 6 and Control
Electrical Interface on page 7.
Rx_DAT
The incoming optical signal is converted and repowered as a differential PECL serial data stream. The
Receive Signal Interface table on page 6 gives the voltage levels and timing characteristics for the Rx_DAT
signals. The transceiver provides the AC coupling for the +Rx/-Rx lines.
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 the incoming
modulated light intensity is below that required to guarantee the correct operation of the link. Normally, this
condition 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 .

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 OMA 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, 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 ratio of 9 dB. At 1.0625 Gb/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 1X9-1063/1250-SW, however, presents a 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.
