4 Pluggable Modules for Interfaces
Description
Uses one Rx single-mode fiber and
one Tx single-mode fiber to transmit
data at 1 Gbit/s over a distance within
40 km.
Uses one Rx single-mode fiber and
one Tx single-mode fiber to transmit
data at 1 Gbit/s over a distance within
100 km.
Uses one single-mode fiber for
bidirectional transmission at 1 Gbit/s
over a distance within 40 km.
Coarse wavelength division
multiplexing, which uses one single-
mode fiber to transmit signals on
multiple channels. It transmits data at
1 Gbit/s over a distance within 80 km.
Dense wavelength division
multiplexing, which uses one single-
mode fiber to transmit signals on
multiple channels. It transmits data at
1 Gbit/s over a distance within 120
km.
Uses one Rx multimode fiber and one
Tx multimode fiber to transmit data at
10 Gbit/s over a distance within 100
m.
Uses one single-mode fiber for
bidirectional transmission at 10 Gbit/
s over a distance within 10 km.
Uses one Rx multimode fiber and one
Tx multimode fiber to transmit data at
10 Gbit/s over a distance within 400
m.
