Module 2.7

Question 1

Fiber optic transceiver module type supporting duplex 1 Gbps (SFP) or 10 Gbps (SFP+) links.

Answer 1

SMall Form Factor Pluggable (SFP)

Question 2

____________ uses LC connectors and is also designed for Gigabit Ethernet.

Answer 2

SFP

Question 3

Enhanced ______________ is an updated specification to support 10 GbE but still uses the LC form factor

Answer 3

SFP (SFP+)

Question 4

Fiber optic transceiver module type supporting four individual duplex lanes at 1 Gbps (QSFP) or 10 Gbps (QSFP+) that can be aggregated into a single 4 Gbps or 40 Gbps channel.

Answer 4

Quad Small Form-Factor Pluggable (QSFP)

Question 5

Enhanced quad small form-factor pluggable (QSFP+) is designed to support 40 GbE by provisioning ___x ___ Gbps links

Answer 5

4 and 10

Question 6

QSFP+ can also be used with _____________________ Ethernet standards.

Answer 6

Wavelength Division Multiplexing (WDM)

Question 7

____________________ support transmit and receive signals over the same strand of fiber

Answer 7

Bidirectional (BiDi) transceivers

Question 8

This uses _______________ to transmit the Tx and Rx signals over slightly shifted wavelengths, such as 1310 nm for Tx and 1490 nm for Rx

Answer 8

WDM

Question 9

Technology for multiplexing up to 16 signal channels on a single fiber using different wavelengths.

Answer 9

Coarse Wavelength Division Multiplexing (CWDM)

Question 10

______________________________ supports up to 16 wavelengths and is typically used to deploy four or eight bidirectional channels over a single fiber strand.

Answer 10

Coarse Wavelength Division Multiplexing (CWDM)

Question 11

Dense Wavelength Division Multiplexing (DWDM) provisions greater numbers of channels (20, 40, 80, or 160). This means that there is much less ___________________ each channel and requires more precise and expensive lasers.

Answer 11

spacing between
