Basics of Fiber Transmission

Fiber Optic Cables- Uses Light Pulses to transmit information along a span



Fiber Optic Cables- Common Connectors, Adapters, and AttenuatorsConnectors

Attenuators• SC UPC• LC PC• ST UPC

Adapters• Dual LC • Dual SC• ST



Fiber Optic Cables- Fiber Types

Single mode fiber• Single path for light • Longer transmission lengths than less expensive Multimode cable• Used with 1310nm, 1550nm, CWDM and DWDM applications

Multimode fiber• Multiple paths for light• Less expensive cable idea for shorterspan lengths.• Used with 850nm and 1310nm wavelengths



Wavelengths- Colors of Light

• The light we are most familiar with is, of course, the light we can see. Our eyes are sensitive to light whose wavelength is in the range of about 400 nanometers (billionths of a meter) to 700 nanometers.

• For fiber optics, we use light in the infrared region which has wavelengths longer than visible light, typically around 850, 1300 and 1550 nm. Why do we use the infrared? Because the attenuation of the fiber is much less there.

• Multimode fiber is designed to operate at 850 and 1300 nm, while single mode fiber is optimized for 1310 and 1550 nm. The difference between 1300 nm and 1310 nm is simply a matter of convention, harking back to the days when AT&T dictated most fiber optic jargon. Lasers at 1310 nm and LEDs at 1300 nm were used in single mode and multimode fiber respectively.


Wavelengths- Colors of Light

Attenuation and Span Lengths• 850nm• 1300/1310nm• 1550nm



Wavelengths- Transmitters

• The most commonly used transmitters LEDs (light emitting diodes) and Laser Diodes

• The transmitter determines the wavelength (color) of the light

Common TransmittersWideband transmitters (850nm, 1310nm, 1490nm,1550nm)

• Transmit with wide bandwidths (50 to 100nm spacing typical)• Most commonly used transmitters in fiber optic communication• Low cost due to high production numbers and looser tolerance requirements than

discrete transmitters

Discrete transmitters• Transmit with narrow bandwidths (20nm spacing CWDM, 50 or 100Ghz spacing

for DWDM)• Used in CWDM, DWDM applications• Cost relative to tolerance requirements




Data Rate- Traffic Speed

• In telecommunications and computing, bitrate (sometimes written bit rate or data rate) is the number of bits that are conveyed or processed per unit of time. Bit rate is often used as synonym to the terms connection speed, transfer rate, channel capacity, maximum throughput and digital bandwidth capacity of a communication system.

• The bit rate is quantified using the 'bit per second' (bit/s or bps) unit, often in conjunction with a SI prefix such as kilo (kbit/s or kbps), Mega (Mbit/s or Mbps), Giga (Gbit/s or Gbps) or Tera (Tbit/s or Tbps).

Reach Extension and 3R Regeneration

Reach Extension: Used when the existing customer equipment does not have enough optical power to cross a span

• RGN cards 3R Regeneration to improve reach distances • Near end, midspan, and far end applications

3R Regeneration: Reshape, Retime, Reamplification

WDM- Wave Division Multiplexing

• Combines two or three wavelengths (1310nm, 1490nm,1550nm) onto a common fiber

• WDM system uses a multiplexer at the transmitter to join the signals together, and a demultiplexer at the receiver to split them apart

• Commonly used with wideband transmitters

CWDM & DWDM Compared


CWDM DWDM Notes:

Cost X

CWDM equipment is a cost effective alternative to DWDM. DWDM offerstighter spacing which requires more precise (>$) filters and cooled (>$)lasers. CWDM with wider channel spacing can utilize less expensive filtersand uncooled (<$) laser technology.

Channels XWith tighter spacing, DWDM technology supports a channel counts up to128. CWDM, with wider spacing offers 16 channels.

Span Length XDue to the DWDM channels being centered on the 1550nm wavelenghts itsuffers less loss over longer spans.

Upgradeable to 10Gbps. X X Both technologies support rates up to 10.3 Gbps and beyond (11.3)

ITU compliant X X Both the CWDM & DWDM networks use ITU compliant wavelengths.

Comparison of CWDM vs. DWDM


Hybrid Wave Division- The mixing of multiple WDM transmitters and Mux/Demux modules to suit a specific application.

• Wideband transmitters over CWDM: Use 1550nm transmission equipment on the 1551nm port of the CWDM Mux/Demux

• Combined DWDM signals over CWDM or WDM: Use a DWDM mux combine up to 8 wavelengths onto a common fiber then connect that common fiber to the 1551nm port on a CWDM to be combined with the other CWDM wavelengths or connect the common fiber to the 1550nm port of a DWDM mux to be combined with a 1310nm signal

Glossary of Terms

SONET/SDH: Synchronous optical networking, is a method for communicating digital information using lasers or light-emitting diodes (LEDs) over optical fiber. The method was developed to replace the Plesiochronous Digital Hierarchy (PDH) system for transporting large amounts of telephone and data traffic and to allow for interoperability between equipment from different vendors.Both SDH and SONET are widely used today; SONET in the U.S. and Canada, SDH in the rest of the world. Although the SONET standards were developed before SDH, their relative global prevalence means that SONET is now considered as the variation.

Attenuation: The decrease in intensity of electromagnetic radiation due to absorption or scattering of photons. Attenuation does not include the decrease in intensity due to inverse-square law geometric spreading. Therefore, calculation of the total change in intensity involves both the inverse-square law and an estimation of attenuation over the path.

Receiver Sensitivity: The sensitivity of an electronic device, e.g., a communications system receiver, or detection device, e.g., PIN diode, is the minimum magnitude of input signal required to produce a specified output signal having a specified signal-to-noise ratio, or other specified criteria.

Insertion Loss: In telecommunications, insertion loss is the decrease in transmitted signal power resulting from the insertion of a device in a transmission line or optical fiber. It is usually expressed relative to the signal power delivered to that same part before insertion. Insertion loss is usually expressed in dB. Insertion loss is sometime referred to as the attenuation of a device.

Protocol: In the field of telecommunications, a communications protocol is the set of standard rules for data representation, signalling, authentication, and error detection required to send information over a communications channel.

Gigabit Ethernet (GigE): A term describing various technologies for transmitting Ethernet packets at a rate of a gigabit per second (nominally 1.25Gbps), as defined by the IEEE 802.3-2005 standard.

IPTV: Internet Protocol Television describes a system where a digital television service is delivered using the Internet Protocol over a network infrastructure, which may include delivery by a broadband connection. For residential users, IPTV is often provided in conjunction with Video on Demand and may be bundled with Internet services such as Web access and VoIP. The commercial bundling of IPTV, VoIP and Internet access is referred to as a Triple Play.

Metro Ethernet: A computer network based on the Ethernet standard covering a metropolitan area. It is commonly used as a metropolitan access network to connect subscribers and businesses to a Wide Area Network, such as the Internet. Large businesses can also use Metro Ethernet to connect branch offices to their Intranets.

FTTx: Fiber to the Premises (FTTP) or Fiber to the Home (FTTH) is a broadband telecommunications system based on fiber-optic cables and associated optical electronics for delivery of multiple advanced services such as the triple play of telephone, broadband Internet and television all the way to the home or business.
