FIBER SOLUTIONS

Fiber Solutions
With the introduction of HDTV, 1.5Gbit, and 3Gbit
bandwidth signals, the need to adopt ?ber interfaces
is a requirement. Fiber offers many bene?ts compared
to copper interfaces, with the greatest advantage
being distance with no degredation of signal quality.
The other bene?ts of ?ber include: sending and
receiving multiple bi-directional signals over a single
?ber link, zero noise or interference, and signi?cantly
less bulk. LYNX Technik has fully embraced ?ber
technology and offers a wide range of solutions to
address ?ber infrastructure design.

LYNX Technik offers a full range of SFP ?ber
sub-modules, which range from basic nonCWDM ?xed wavelength transmitters to a full
range of CWDM transmitters with 18 selectable
wavelengths. The solutions are ideal for
simple point-to-point applications or complex
multiplexed applications.
Our basic SFP modules support distances up
to 10km, and our CWDM solutions support
distances up to 40km or 80km.

Module and Backplane Connected

CWDM

LYNX Technik offers comprehensive support for CWDM (Coarse Wavelength Division Multiplexing) with 18
selectable laser wavelengths as speci?ed by ITU-T G692.2. CWDM is a process used to optically multiplex
signals into a single ?ber link. By selecting different wavelength ?ber transmitters and using the LYNX OCM
passive optical multiplexers, it is easy to con?gure a bi-directional CWDM ?ber transmission system. Our
CWDM solutions service distances up to 40km, and our long-haul transmitters and receivers are suitable
for applications up to 80km.

Fiber Implementation
A host of Series | 5000 modules now provide ?ber optic I/O
capability. While ?ber I/O is not unique for terminal equipment,
the LYNX Technik implementation is extremely well engineered.
LYNX Technik uses small and modular SFP sub-modules for ?ber
I/O. Adding ?ber capability or changing system con?gurations
(wavelengths) is straightforward and simple.

Non-CWDM
SFP Fiber Sub Module

CWDM Fiber modules use precision narrow band lasers and therefore cost more. For simple applications
that only require single point to point ?ber connections, a “non CWDM” or basic ?ber SFP module is a more
cost-effective solution.

Passive Fiber System Components

Working with light vs. electricity allows for us to use passive optical building blocks for a ?ber optic system
design. Passive = no power requirements. Our solutions for ?ber include optical CWDM multiplexers,
splitters, and combiners. We adhere to the highest standards of superior technical performance and all of
our products are designed and manufactured in Germany.

Fiber Option Selection Tables

We offer a wide range of SFP ?ber options for our modules which include ?ber support in this section
of the catalog. The module listings will refer to the tables show on the next page for the selection of the
appropriate SFP ?ber option.
Fiber Backplane Sockets on Module

Backplane with Integrated Fiber

LLYNX Technik ?ber solutions are unique in that the ?ber I/O is integrated into the backplane assembly.
This means the module can be removed the rack for ease of service and without disconnecting the
?ber cables from the module. Other solutions on the market often have the ?ber I/O directly ?xed to
the module and fed through the rear of the rack. When a module is removed, the delicate ?ber cables
are pulled, which can result in damage. There is also no requirement for ?ber “service loops” on the
modules.
