70-km Gigabit Ethernet
GBIC Transceiver
Installation Guide
For 3Com Gigabit Interface Converter (GBIC) Transceivers
Description
The Gigabit Interface Converter (GBIC) ports on your system connect to
Gigabit Ethernet networks through a GBIC transceiver (Figure 1),
providing a high-speed connection over fiber-optic cable. The transceiver
connects to the network using a fiber-optic duplex Subscriber Connector
(SC). You can remove and replace the transceiver with the system on
(which is called hot-swapping).

To ensure optimal performance, compatibility, and regulatory compliance,
use only GBIC transceivers that 3Com supports. For a list of currently
supported GBICs, see this 3Com Web site:

- Page 10 70-km Gigabit Ethernet GBIC Transceiver Installation Guide The budget figures for all three of the sample systems reflect conservative values for fiber attenuation and connector attenuation to assure operation at 70 km under typical to less-than-ideal conditions. Link distances of greater than 70 km can be attained when conditions allow. Fiber attenuation of 0.19 dB per km and lower is possible, allowing link lengths beyond 70 km.
