The Application of Optical Fiber Patch Cord in High-density Data Center

---

Optical fiber patch cords are widely used
in data centers. In recent years, the demand for bandwidth in data center
optical fiber transmission systems has shown a trend of high growth. Therefore,
the use of a new generation of optical fibers and optical modules can continue
to explore the potential of optical fiber network bandwidth growth. Because
multi-mode fiber jumpers have great advantages in cost, they have an absolute
advantage in data center applications.

 

Driven by the continuous application and
promotion of network media in the cloud computing environment, multi-mode fiber
optic patch cords are also constantly developing. From OM1 to OM2, and from OM3
to OM4, the VCSEL laser optimization technology used, and bandwidth
requirements are constantly increasing. The introduction of the new category
OM4 multi-mode patch cord fiber standard EIA/TIA492AAAD provides a better
transmission method for the wide application of multi-mode fiber in the future.
This article will provide an ideal communication solution for your data center,
server, network switch, telecommunication switching center and many other
embedded application systems that require high-speed data transmission.

 

In 40G/100G data transmission applications,
the transmission port connection equipment, such as QSFP optical module, will
be directly connected through MTP/MPO connectors regardless of the number of
optical fiber connections used by the optical fiber channel, and regardless of the
type of optical fiber connection. Because the 40G/100G data transmission
application device and the channel connection between the device need to form a
special mode, so that the channel of the transmitting end and the receiving end
of the device correspond to each other, which requires the MTP/MPO
connector to complete the connection.

 

MPO / MTP fiber optic patch cords can
provide various applications for all networks and devices that require 100G
modules. They adopt the MT series casing design of the high-density multi-mode
fiber optic connector system industry, and the MPO/MTP fiber jumpers use UPC
and APC polished end faces, and support both multi-mode and single-mode
applications. With VCSEL laser and LED light source, 10G OM3/OM4 MPO/MTP fiber
optic patch cords can provide 10Gbps data transmission rate in high bandwidth
applications. They are 5 times faster than standard 50um fiber optic patch
cords.

 

At the same time, multimode MPO / MTP fiber
optic patch cords are also a more economical choice for most of the most common
fiber optic communication systems. Single-mode MPO/MTP fiber jumpers are mainly
used in long-distance data transmission systems. MPO/MTP backbone jumpers are
specially designed for data center applications. Generally, single-mode and
multi-mode MPO/MTP fiber jumpers are designed as round cables with an outer
diameter of 3mm or 4.5mm. The connectors at both ends of the cable are also
called MPO/MTP connectors.

 

At present, MPO/MTP high-density push-pull
optical fiber jumpers are mainly used in three aspects: high-density cabling
data centers, fiber to the home, and connection applications with optical
splitters, 40G/100G QSFP+, SFP+ and other optical modules. Today, there are
already a series of high-density parallel optical interconnection products that
can adapt to the optical fiber transmission of modern data centers, such as
custom MPO/MTP fiber jumpers, multi-mode fiber loopbacks and QSFP+ high-speed
cable assemblies.

 

The development of server virtualization
and cloud computing, as well as the development trend of network integration,
has brought about the development of faster and more efficient data center
networks. At present, the 10G switch composed of 48 10G channels is mainly
limited to use SFP+ modules to realize the connection. In order to meet higher
bandwidth requirements, users can use high-density QSFP+ high-speed cables to
complete the connection, and increase the data transmission rate of each channel
and increase the port density to meet the customer’s high bandwidth
requirements.
