Description
The 1.0625/2.125Gbps Serial Optical Converter
(SFF-PTH-2125-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-2125-SW/LW-2X5/2X6 conforms to the
American National Standards Institute’s (ANSI)
Fibre Channel, FC-PI specification for short and
long wavelength operation (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-2125-SW/LW-2X5/2X6 is ideally
suited for Fibre Channel applications which include
point to point links as well as Fibre Channel Arbi-
trated 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 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
1.0625Gb/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-PTH-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 a PTH connector interfac-
ing the SFF-PTH-2125-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-2125-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 shutting off the laser transmitter.
