Description
The 1.0625/2.125Gbps Serial Optical Converter
(SFF-PGG-2125-SW/LW) is an integrated fiber optic
transceiver that provides a high-speed serial link at
a signaling rate up to 2.125Gb/s. The SFF-PGG-
2125-SW/LW 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-PGG-2125-SW/LW 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 hot-pluggable (PGG) module
which has a 2 by 10 electrical surface mount con-
nector assembly.
The SFF-PGG-2125-SW/LW transceiver features a
Serial ID module. The Serial ID module can store up
to 128 bytes of vital product data.
The SFF-PGG-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 550m at
1.0625Gb/s and 300m at 2.125Gb/s. A 50/125
μ
m
multimode optical fiber, terminated with an industry
standard LC connector, is the preferred medium. (A
62.5/125
μ
m multimode fiber can be substituted with
shorter maximum link distances.)
The SFF-PGG-2125-LW uses a long wavelength
(1310nm) edge emitting laser. This enables data
transmission over optical fibers at distances up to
10,000m on a single mode (9/125
μ
m) optical fiber.
Encoded (8B/10B) [3], [4], gigabit/sec serial differen-
tial PECL signals traverse the connector interfacing
the SFF-PGG-2125-SW/LW 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-PGG-2125-SW/LW 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.
