Toronto, ON - GAO Tek Inc. has released a series of 3Com compatible GBICs. It is
100% compatible with 3Com's original products. We offer high quality products at
competitive prices, provide on-time delivery and great customer services.
GBICs are input/output transceivers designed to transform signals between
Ethernet and fiber optic networks. One end of the transceiver plugs into a
Gigabit Ethernet port at the switch and the other connects to fiber optic patch
cords linking to the network. GBIC classifications are based on their working
wavelengths, data transmission rates, working power, and working distance. In
general, an SC type interface is located at the fiber optic end of transceiver.
The laser unit in a GBIC module can be 850nm VCSEL, 1310nm FP, 1310nm DFB, and
1550nm DFB.
GBIC transceivers are hot pluggable; this feature allows a suitably designed
enclosure to be changed from one type of external interface to another simply by
plugging in a GBIC with the alternative external interface. GBIC transceivers
are suitable for interconnections in Gigabit Ethernet hubs and convenient for
switching environment. The converters are practically designed for high
performance, point-to-point communicationand fiber channel interconnections.

Features for typical types GBIC modules:
. Compliant with Gigabit Interface Converter (GBIC) Revision 5.5
. Compliant with proposed specifications for IEEE 802.3z/Gigabit Ethernet
. Up to 1.25Gb/s bi-directional data link
. Various kinds of wavelength and working distances optional
. Extended power supply +3.3/5.0V compatible
. Hot pluggable
. Low EMI
. Low power dissipation
. Class 1 Laser Product Compliant with the Requirements of IEC 60825-1 and IEC 60825-2

We offer compatible 3Com transceiver models now:
