Overview
The IBM 1063/1250 Mb/s Gigabit Interface Convert-
ers (GBIC-1063N, GBIC-1063NS, GBIC-1063N-LW,
GBIC-1063NS-LW, GBIC-1250NS, and GBIC-
1250NS-LW) are integrated fiber optic transceivers
that provide high-speed serial links at a signaling
rate of 1062.5 to 1250 Mb/s. GBIC-1063N and
GBIC-1063NS conform 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) [1]; GBIC-1250NS con-
forms to IEEE 802.3z 1000Base-SX standard [2].
GBIC-1063N-LW and GBIC-1063NS-LW conform to
ANSI Fibre Channel FC-0 specification for long
wavelength operation (100-SM-LC-L) [3]; GBIC-
1250NS-LW conforms to IEEE 802.3z 1000Base-LX
standard.
with shorter maximum link distances.
IBM GBIC-1063N-LW, GBIC-1063NS-LW, and
GBIC-1250NS-LW use long wavelength (1310nm)
lasers. This enables data transmission over optical
fibers at distances up to 10km on a single mode
(9/125µm) optical fiber, and distances up to 550m
on multimode (50/125µm) optical fiber.
IBM GBIC-1063NS, GBIC-1063NS-LW, GBIC-
1250NS, and GBIC-1250NS-LW feature a serial ID
module. The serial ID module can store up to 128
bytes of vital product data.
Encoded (8B/10B) [5, 6], gigabit/sec, serial, differen-
tial, PECL signals traverse a 20-pin straddle mount
connector interfacing the GBIC to the host card. The
serial data modulates the laser and is sent out over
the outgoing fiber of a duplex cable.
These Gigabit Interface Converters (GBICs) are ide-
ally suited for Fibre Channel Arbitrated Loop (FC-
AL) and Gigabit Ethernet applications, but can be
used for other serial applications where high data
rates are required. These modules are hot-plugga-
ble and permit easy manufacturing and field configu-
ration between shortwave, longwave, and copper
implementations of the various standards.
Incoming, modulated light is detected by a photore-
ceiver mounted in the SC 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 Serial-
izer/Deserializer modules.
The GBIC-1063N, GBIC-1063NS, and GBIC-
1250NS use short wavelength (850nm) VCSEL
lasers. This enables low cost data transmission over
optical fibers at distances up to 550m. A 50/125µm
multimode optical fiber, terminated with an industry
standard SC connector, is the preferred medium. A
62.5/125 mm multimode fiber can be substituted
These IBM 1063/1250 Mb/s Gigabit Interface Con-
verters are Class 1 laser safe products. 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.
