Optical Fiber, Optical Connector, and Fiber Adapter
Optical Fibers
Optical fibers are classified into single-mode fibers and multimode fibers.
lSingle-mode fibers have a diameter of 5-10 μm and transmit laser light in one mode with
a specified wavelength. These fibers support a wide frequency band and a high transmission
capacity, so they are used for long-distance transmission. Most single-mode fibers are
yellow, as shown in Figure 6-4.
lMultimode fibers have a diameter of 50 μm or 62.5 μm and transmit laser light in multiple
modes with a specified wavelength. These fibers have a lower transmission capacity than
single-mode fibers and are used for short-distance transmission. Model dispersion occurs
during transmission over multimode fibers. Most multimode fibers are orange, as shown
in Figure 6-5.

6.3 Network Cable
6 Cables
Types of Network Cables
A network cable connects a maintenance terminal to the console port on the main control board
for local or remote maintenance.
Network cables are classified into straight-through cables and crossover cables.
lStraight-through cable: The twisted pairs in the RJ45 connectors at both ends are crimped
in the same sequence. A straight-through cable connects two devices of different types, for
example, a PC and a switch.
lCrossover cable: The twisted pairs in the RJ45 connectors at two ends are crimped in
different sequences. A crossover cable connects two devices or interfaces of the same type,
for example, two PCs.
Huawei switches support both straight-through and crossover cables and their ports are adaptive
to the cable types.

7 Pluggable Modules for Interfaces
7.1 Important Notes About Using Optical Modules Certified
for Huawei Switches
7.1.1 How to Identify Huawei-Certified Optical Modules
NOTICE
l Huawei switches must use Huawei-certified optical modules. Non-Huawei-certified optical
modules cannot ensure transmission reliability and may affect service stability. Huawei is
not liable for any problem caused by the use of non-Huawei-certified optical modules and
will not fix such problems.
l The methods provided here are only for reference. To confirm whether optical modules you
use have been certified by Huawei, contact Huawei Technical Assistant Center (TAC).
If the optical modules you use are delivered after July 1, 2013, use either of the following methods
to determine whether they have been certified by Huawei.
Method 1: Check for "HUAWEI" on the Label
If an optical module has been certified by Huawei, its label contains "HAUWEI", as shown in
Figure 7-1.
Figure 7-1 "HUAWEI" on the label of a Huawei-certified optical module
Method 2: Run the display transceiver Command
If an optical module meets the following conditions, it has been certified by Huawei. Otherwise,
the optical module is not a Huawei-certified one.
lIn the display elabel command output, the Manufactured field displays a date later than
2013-07-01.
lIn the display version command output, the display version is V200R001C00 or later.
lIn the display transceiver command output, the Manufacturing Date field displays a date
later than 2013-07-01, and the Vendor Name field displays HUAWEI.
7.1.2 Risks of Using Non-Huawei-Certified Optical Modules
During certification of optical modules for Huawei switches, Huawei completes comprehensive
functionality verification to ensure quality of optical modules. The verified items include optical
module plug/unplug, transmit optical power, receive optical power, signal transmission quality,
Issue 12 (2015-07-31)Huawei Proprietary and Confidential

Hardware Description
data reading, error tolerance, compatibility, electromagnetic compatibility (EMC), and
environmental parameters.
Non-Huawei-certified optical modules may cause the following problems:
lNon-standard structure and size cause failures to install optical modules on adjacent optical
interfaces.
Structures or sizes of some non-Huawei-certified optical modules do not comply with the
Multi-Source Agreement (MSA). When such an optical module is installed on an optical
interface, the size of this optical module hinders optical module installation on adjacent
optical interfaces.
lData bus defects cause suspension of a switch's data bus.
Some non-Huawei-certified optical modules have defects in data bus designs. Using such
an optical module on a switch causes suspension of the connected data bus on the switch.
As a result, data on the suspended bus cannot be read.
lImproper edge connector size damages electronic devices of optical interfaces.
If a non-Huawei-certified optical module with improper edge connector size is used on an
optical interface, electronic devices of the optical interface will be damaged by short
circuits.
7 Pluggable Modules for Interfaces
lUnnormalized temperature monitoring causes incorrect alarms.
The temperature monitoring systems of some non-Huawei-certified optical modules do not
comply with industry standards and report temperature values higher than the real
temperature. When such optical modules are used on a switch, the system will report
incorrect temperature alarms.
lImproper register settings cause errors or failures in reading parameters or diagnostic
information.
Some non-Huawei-certified optical modules have improper register values on page A0,
which can cause errors or failures when the system attempts to read parameters or diagnostic
information from a data bus.
lSome non-Huawei-certified optical modules are not designed in compliance with EMC
standards and have low anti-interference capability. Additionally, they bring
electromagnetic interference to nearby devices.
lThe operating temperature ranges of non-Huawei-certified optical modules cannot meet
service requirements. When they are used under relatively high temperature, the optical
power decreases, resulting in service interruption.
7.2 Understanding Optical Modules
7.2.1 What Is an Optical Module
On an optical network, a sender needs to convert electrical signals into optical signals before
sending them to a receiver, and the receiver needs to convert received optical signals into
electrical signals. An optical module is a component that completes electrical/optical conversion
on an optical network. Figure 7-2 shows the structure of an optical module.

7.2.2 Types of Optical Modules
Optical modules are available in various types to meet diversified requirements.
lClassified by transmission rates
Depending on transmission rates, optical modules are classified into 40GE, 10GE and GE
optical modules.
lClassified by encapsulation types
The higher transmission rate an optical module provides, the more complex structure it has.
Optical modules are encapsulated in different modes to provide different structures. Huawei
switches support optical modules of the following encapsulation types: QSFP+, SFP, eSFP,
and SFP+.
– SFP: small form-factor pluggable. SFP optical modules support LC fiber connectors
and are hot swappable.
– eSFP: enhanced small form-factor pluggable. An eSFP module is an SFP module that
supports monitoring of voltage, temperature, bias current, transmit optical power, and
Issue 12 (2015-07-31)Huawei Proprietary and Confidential
receive optical power. Therefore, eSFP is also called SFP sometimes.
– SFP+: small form-factor pluggable plus, SFP with a higher rate. SFP+ optical modules
are more sensitive to electromagnetic interference (EMI) because they have a higher
S6700 Series Ethernet Switches
Hardware Description7 Pluggable Modules for Interfaces
rate. To reduce EMI, SFP+ optical modules have more springs than SFP optical modules
and the cages for SFP+ modules on a card are tighter.
– QSFP+: quad small form-factor pluggable. QSFP+ optical modules support MPO fiber
connectors and are larger than SFP+ optical modules.
lClassified by physical layer standards
Different physical layer standards are defined to allow data transmission in different modes.
Therefore, different types of optical modules are produced to comply with these standards.
The Standard column of Table 7-1 lists the physical layer standards.
lClassified by modes
Optical fibers are classified into single-mode and multimode fibers. Therefore, optical
modules are also classified into single-mode and multimode modules to support different
optical fibers.
– Single-mode optical modules are used with single-mode fibers. Single-mode fibers
support a wide band and large transmission capacity, and are used for long-distance
transmission.
– Multimode optical modules are used with multimode fibers. Multimode fibers have
lower transmission performance than single-mode fibers because of modal dispersion,
but their costs are also lower. They are used for small-capacity, short-distance
transmission.
Table 7-1 provides optical module classification based on different factors.

Transmit optical power
Output optical power of an optical module when it is working properly. When two optical
modules are connected, the transmit optical power of one end must be within the range
of receive optical power on the other end.
Receive optical powerAverage input optical power that the receiver of an optical module can receive within a
range of bit error rate (BER = 10
-12
). The upper limit of this parameter is the overload
optical power and the lower limit is the maximum receiver sensitivity. When two optical
modules are connected, the receive optical power on one end determines the range of
transmit optical power on the other end.
Maximum receiver
sensitivity
Minimum average input optical power that the receiver of an optical module can receive
within a range of bit error rate (BER = 10
-12
). When two optical modules are connected,
the maximum receiver sensitivity on one end determines the minimum value of transmit
optical power on the other end.
Overload optical power Maximum average input optical power that the receiver of an optical module can receive
within a range of bit error rate (BER = 10
-12
). When two optical modules are connected,
the overload optical power on one end determines the maximum transmit optical power
on the other end.
Extinction ratioMinimum ratio of the average optical power with signals transmitted against the average
optical power without signals transmitted in complete modulation mode. The extinction
ratio indicates the capability of an optical module to identify signal 0 and signal 1. This
parameter is a quality indicator for optical modules. Optical modules with a large
extinction ratio may not have good quality. Qualified optical modules should have an
extinction ratio complying with IEEE 802.3.
Issue 12 (2015-07-31)Huawei Proprietary and Confidential
S6700 Series Ethernet Switches
Hardware Description
Fiber modeMode of optical fibers defined based on core diameters and features of optical fibers.
Optical fibers are classified into single-mode and multimode fibers. Generally,
multimode fibers have large core diameters and severe dispersion, so they are used to
transmit optical signals over short distances. Single-mode fibers have smaller diameters
and small dispersion, so they can transmit optical signals over long distances.
Modal bandwidthBandwidth measured at a point with transmit power several dB lower than that of the
point with the peak center wavelength. Modal bandwidth reflects spectrum
characteristics of multimode fibers. The higher modal bandwidth a multimode fiber has,
the longer transmission distance the fiber supports.
Fiber diameterDiameter of the core of a fiber. According to international standards for optical fibers,
the diameter of a multimode fiber is 62.5 um or 50 um, and the diameter of a singlemode fiber is 9 um. Select optical fibers with diameters supported by the optical modules.
Fiber classOptical signals with different wavelengths have their best working windows in different
optical fibers. To help efficiently adjust wavelengths or dispersion features of optical
fibers and change their refractive indexes, the following fiber classes are defined:
multimode fiber (G.651), common single-mode fiber (G.652), shifted dispersion fiber
(G.653), and non-zero shifted dispersion fiber (G.655). G.651 and G.652 are commonly
used fiber classes. Optical fibers of higher classes support longer transmission distances.
When selecting optical fibers for optical modules, determine the classes of fibers based
on the required transmission distances.
7 Pluggable Modules for Interfaces
Connector typeType of the interface on an optical module to accommodate a fiber. Commonly used
connector types are LC (applicable to all the SFP, SFP+, and XFP modules), SC, and
MPO (applicable to 150 m QSFP+ and CXP modules). Select optical fibers with
connectors supported the optical modules.
Transmission distanceMaximum distance over which optical signals can transmit. Optical signals sent from
different types of sources can transmit over different distances due to negative effects of
optical fibers, such as dispersion and attenuation. When connecting optical interfaces,
select optical modules and fibers based on the maximum signal transmission distance.
Interface rateMaximum rate of electrical signals that an optical component can transmit without bit
errors. The interface rates defined in Ethernet standards include 125 Mbit/s, 1.25 Gbit/
s, 10.3125 Gbit/s, and 41.25 Gbit/s. When connecting optical interfaces, select optical
modules and fibers based on the maximum signal transmission rate.
Center wavelengthWavelength measured at the midpoint of the half-amplitude line in the transmit spectrum.
Two connected optical modules must have the same center wavelength.
MSAMulti-Source Agreement, a non-profit organization jointly established by optical module
manufacturers. This agreement defines the structure and dimensions of optical
transceivers by referring to Optical Internetworking Forum (OIF) and International
Telecommunication Union (ITU) standards.
