Description
The 1.0625/2.125 Gbps Small Form Factor (SFF-
PTH-SW-2X5/2X6) is an integrated fiber optic trans-
ceiver that provides a high-speed serial link at a sig-
naling rate up to 2.125 Gb/s. The SFF-PTH-SW-
2X5/2X6 conforms to the American National Stan-
dards Institute’s (ANSI) Fibre Channel, FC-PI speci-
fication for short wavelength operation (200-M5-SN-
I, 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 trans-
ceiver 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 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 or 2 by 6 electrical connector pin
configuration.
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
1.0625 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 differen-
tial PECL signals traverse a PTH connector interfac-
ing 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 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-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.
