Tutorial: Optical Ethernet

From the new textbook Telecom 101 Fifth Edition: 2020

SFP optical transceivers

Figure 111. SFP Optical Transceivers

10.5 Optical Ethernet

Optical Ethernet is signaling MAC frames (Section 4.4) from one device to another by flashing a light on and off; light on represents a 1 and light off represents a 0 in many systems.

The light, called a wavelength or lamda – λ in Greek – is as close to one single pure frequency as possible, in the infra-red, lower frequencies than what our eyes detect.

In sophisticated systems, the wavelength might be modulated with QAM (Section 3.4) to increase the bit rate.

Normally, Optical Ethernet is implemented as point-to-point connections: from a hardware port on one switch or router to a hardware port on another switch or router in a different building. This includes connections between core routers in cities, connections between routers and switches within a city, and connections from carriers to customers.

10.5.1 SFP Modules and Connectors

The light is generated by a laser controlled by pulses of electricity at the transmitter.  The intensity and sometimes phase of the light is modulated, i.e. changed in discrete steps, to represent bits optically based on the pulses of electricity. Up to 80 km (50 miles) away at the other end of a tube of glass thinner than one of your hairs, a photodetector at the receiver measures the received light and decides what bits are being represented, and transmits them onward as pulses of electricity.

As illustrated in Figure 111, most systems use two fibers, one for each direction. A device combining the transmitter and detector functions is called an optical transceiver.

This device has metal connectors on one side to plug into a slot on a router or switch, and optical connectors on the other side, either factory- or field-installed on the fibers plugged into the transceiver.

These transceivers are typically implemented as Small Form-factor Pluggable (SFP) modules, which are hot-swappable in the terminating equipment at each end.

100 Gb/s being communicated through this transceiver is the high end of commercially-deployed technology in 2020.

In some cases, the SFP modules are embedded in the terminating equipment, meaning the fibers are plugged into the terminating equipment. This allows re-use of existing fiber. In other cases, the SFP modules are attached to fiber cables by the fiber cable manufacturer, meaning the SFP module is plugged into the terminating equipment. This ensures the fiber and transceiver technology are matched and the optical connection is a high-quality “factory” connection.

The SFP module format is not the subject of a standard, but rather described in industry Multiple Sourcing Agreements (MSA).

10.5.3 IEEE Standards

There are many technologies for transceivers implemented in the SFP module. Some are proprietary; many are standardized by the IEEE. In practice, the same manufacturer’s product is used at both ends of the fiber to ensure compatibility. The table in Figure 112 lists current IEEE standards. More will be published in the future.

SFP optical transceivers

Figure 112. IEEE Optical Ethernet Standards

Most technologies use one fiber for each direction. Some, like for fiber to the home, use two wavelengths for two directions on one fiber. The bitrate of the standards beginning with 1000 is 1,000 Mb/s, or 1 Gb/s. A G at the beginning means Gigabits/second.  40 and 100 Gb/s technologies split the bitstream into subrates and transmit them in parallel on different wavelengths called paths or lanes.

The reach is the maximum length of fiber between devices.  Single-mode and multimode are designations for different qualities of fiber.  Most if not all builds today use single-mode fiber.

Automatic CTNS Course Updates and Package Upgrades

In the constantly-evolving world of telecom, it is essential to keep training courses up to date.

The reason why so many people appreciate Teracom’s Online Courses and TCO Certification Packages is because they are based on Teracom’s instructor-led courses, with the selection of material, its order, timing and explanations tuned and refined in the classroom over the course of years, and constantly updated.

This also means that updates to instructor-led courses are subsequently reflected in online courses, keeping them up to date.

Following the major update to instructor-led Course 101 Broadband, Telecom, Datacom and Networking for Non-Engineers (Days 1 – 3 of BOOT CAMP) in 2020, updates to many online courses will be rolling out over the next months.

Certified Telecommunications Network Specialist (CTNS) is our most popular package of six online courses plus TCO Certification.

All six CTNS courses are being updated.  Update of Course 2201 The PSTN is complete.  A significant update to Course 2206 Wireless Telecommunications will be published in the next weeks.  Updates to the OSI Layers, Ethernet, IP and MPLS courses will follow.

All customers who have purchased the CTNS package, or any of the courses individually, will automatically receive the updates in their dashboard.

Stay tuned for an exciting announcement of an upgrade to the CTNS package, increasing the package from six courses to eight, with the inclusion of a brand new course #1 in the lineup “Introduction to Broadband Telecommunications” plus “Fundamentals of Voice over IP”.

The price of the CTNS package will increase when the number of courses increases from six to eight. Since all existing customers will automatically get the two new courses at no additional charge, you can beat the price increase by purchasing CTNS before the upgrade and get the two new courses, when they are released, for free!
