Multiple Select

Select the different types of fiber cable (select 2)

• Fiber Optic Cable
• Multi-Mode Fiber

• Single-Mode Fiber

• Duplex Mode Fiber

Categorize

Options (15)

Small core allowing only one light to pass through

Light travels directly down the fiber with minimal reflection and attenuation

Suitable for long distances

Long-haul networks, high-speed broadband, telecommunications

More expensive

Larger core allowing multiple light modes to pass through 

Light bounces more causing more dispersion and attenuation

Best for shorter distances

Datacenters, LANs

Less expensive

Single Mode

Multimode

What is WDM?

Categorize

Options (14)

Supports Tx and Rx over the same fiber strand

Uses shifted wavelengths (1310 nm for Tx, 1490 nm for Rx)

Requires installation in opposite pairs

Documented in Ethernet standards (1000BASE-BX, 10GBASE-BX)

Supports up to 16 wavelengths

Typically used for 4-8 bidirectional channels on a single strand

Can also be used for unidirectional channels on dual strands

Provisions more channels (20, 40, 80, or 160)

Requires precise lasers due to less spacing between channels

Supports multi-channel
1G, 10G, and 40G Ethernet links

Transceivers installed in opposite pairs for proper function
