Description
The 1063 / 1250 Mb/s Serial Optical Converter
(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.

Laser Safety Compliance Requirements
The SFF-1063/1250N-SW is designed and certified
as a Class 1 laser product. If the power supply volt-
age exceeds 4.0 volts, this may no longer remain a
Class 1 product. The system using the SFF-
1063/1250N-SW must provide power supply over
voltage protection that guarantees the supply does
not exceed 4.0 volts under all fault conditions.
Caution: Operating the power supply above 4.0V or
otherwise operating the SFF-1063/1250N-SW in a
manner inconsistent with its design and function
may result in hazardous radiation exposure, and
may be considered an act of modifying or new man-
ufacturing of a laser product under US regulations
contained in 21 CFR(J) or CENELEC regulations
contained in EN 60825. The person(s) performing
such an act is required by law to recertify and
reidentify the product in accordance with the provi-
sions of 21 CFR(J) for distribution within the United
States, and in accordance with provisions of CEN-
ELEC EN 60825 (or successive regulations) for dis-
tribution within the CENELEC countries or countries
using the IEC 825 standard.
ESD Handling
Take normal static precautions during handling and
assembly of the SFF-1063/1250N-SW to prevent
damage and/or degradation that can be induced by
electrostatic discharge.
