Changes to transmission speeds and expansion in data center
capacities have driven the 100 Gigabit Ethernet.
IHS Infonetics reports that by 2019, 100G Ethernet will make up
more than 50 percent of data center optical transceiver transmissions.
For 100G transceivers,
there are 100GBASE-SR4, SR10 and PSM4 for short-distance transmission
and 100GBASE-CWDM4, LR4 and ER4 for long-distance
transmission
100G Transceivers Transmission
Principles
100GBASE-SR4 QSFP28 transceiver
uses a 12-fiber MMF
strand MTP/MPO cable for 100m connectivity
(4 Tx and 4 Rx, each lane
providing 25 Gbps of throughput over 850nm wavelength).
100GBASE-SR10 CFP optics
use a 2×12-fiber or 24-fiber MMF
strand MPO/MTP cable for 150m connectivity
(10 Tx and 10 Rx, each lane
providing 10 Gbps of throughput over 850nm wavelength).
100GBASE-PSM4 QSFP28 transceiver
uses a 12-fiber SMF strand
MTP/MPO cable for 500m connectivity
(4 Tx and 4 Rx, each lane providing 25
Gbps of throughput over 1310nm wavelength).
100GBASE-CWDM4 QSFP28 transceiver
provides aggregated 100G
data rate over 2 km on SMF.
The four optical signals from the four
wavelengths are multiplexed
and coupled to SMF through an industry-standard
LC connector,
and on the receive side, the demultiplexer splits the four
wavelengths apart
100GBASE-LR4 transceivers
provide 100G data rate over 10 km
on SMF.
The four optical signals from the four wavelengths are multiplexed
and coupled to SMF through an industry-standard LC connector, and on the receive
side,
the demultiplexer splits the four wavelengths apart.
100GBASE-ER4 transceivers
provide 100G data rate over 40 km
on SMF.
The four optical signals from the four wavelengths are multiplexed
and coupled to SMF through an industry-standard LC connector, and on the receive
side, the demultiplexer splits the four wavelengths apart.
