Teracom Training continues to update the training material for the 2020s.
The CTSME Certification Package includes four TCO Certification Packages: CTNS, CVA, CWA and CTA, with unlimited repeats and no time limits, the distinctive Certified Telecommunications Subject Matter Expert CTSME Certification and a signed, sealed and framed certificate for $1495.
Here’s what you get:
CTA Certification Package Unlimited Plan. 16 courses covering all major topics in telecom, datacom and networking from POTS to MPLS plus the Security module. CVA Certification Package Unlimited Plan. Six courses providing depth on Voice over IP from packetization to SIP trunking. CWA Certification Package Unlimited Plan. Three in-depth courses on wireless including spectrum, propagation, cellular and mobility, Bluetooth, Wi-Fi and more. CTNS Certification Package Unlimited Plan. CTNS is a subset of CTA, six of the sixteen CTA courses and exams – yet recognized as the #1 telecommunications certification worldwide and a valuable credential to add to your résumé.
We are so confident of the quality of the training, it comes with a 30‑day no questions asked 100% money‑back guarantee.
Terms and Conditions: Buy CTNS, CTA, CVA and CWA at the same time and receive the special bundle price OR buy the certifications one by one and the upgrade to the CTSME certification at the special bundled price when you are ready.
New Course 2241 Introduction to Broadband Telecommunications along with existing Course 2221 Fundamentals of Voice over IP will be added to the CTNS Certification Package before year-end.

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
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.
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
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.
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!
