Description
The 1063/1250 Mb/s Small Form Factor PTH Trans-
ceiver (SFF-1063/1250N-SW) is an integrated fiber
optic transceiver that provides a high-speed serial
link at a signaling rate of 1062.5 to 1250 Mb/s. The
SFF-1063/1250N-SW conforms to the American
National Standards Institute’s (ANSI) Fibre Channel,
FC-0 specification for short wavelength operation
(100-M5-SN-I and 100-M6-SN-I). It also conforms to
draft 2 of the IEEE 802.3z, 1000Base-SX standard
[2].
The SFF-1063/1250N-SW is ideally suited for Fibre
Channel Arbitrated Loop (FC-AL) and Gigabit Ether-
net applications, but can 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 connec-
tor pin configuration.
The SFF-1063/1250N-SW uses a short wavelength
(850nm) VCSEL (Vertical Cavity Surface Emitter
Laser) source. This enables low cost data transmis-
sion over optical fibers at distances up to 550m. A
50/125µm multimode optical fiber, terminated with
an industry standard LC connector, is the preferred
medium. (A 62.5/125µm multimode fiber can be
substituted with shorter maximum link distances.)
Encoded (8B/10B) [3], [4], gigabit/sec, serial, differ-
ential, PECL signals traverse a connector interfac-
ing the SFF-1063/1250N-SW 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-1063/1250N-SW 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.
