3.5.1 What Precautions Should Be Taken When Using Optical Fibers?
Optical Fiber Overview
The connector type of an optical fiber is the same as the interface type of the optical module to which the optical fiber is connected. Connector types of optical fibers include LC, SC, FC, ST, MU, and MPO. LC connectors are the most widely used.
Optical fibers are classified into multimode and single-mode optical fibers:
- Most of multimode optical fibers are orange, but a few multimode optical fibers are other colors. For example, optical fibers with MPO connectors are light green. Multimode optical fibers can be used with multimode optical modules to implement low-cost, short-distance transmission.
- Single-mode optical fibers are yellow. They can be used with single-mode optical modules to implement long-distance transmission.
Precautions for use of Optical Fibers
- The bend radius of optical fibers must be larger than the minimum bend radius allowed by the optical fibers. Otherwise, the optical fibers will be damaged, and quality of optical signals will degrade.
- Do not look into an optical port without eye protection, or the laser may hurt your eyes.
- It is recommended that idle fiber connectors be covered with dust-proof caps to keep the fiber connectors clean. An unclean fiber connector may degrade the quality of optical signals or even cause link failures or error codes on the link.

3.5.4 What Precautions Should Be Taken When 1-to-4 Optical Jumpers Are Routed Through Optical Distribution Frames?
If 1-to-4 optical jumpers are routed to optical distribution frames (ODFs) and connected to four 10GE multimode optical fibers each to transmit data over a certain distance, pay attention to the following points:
- Determine the fiber connector type (LC/FC) supported by the ODF and select appropriate optical jumpers for the supported connector type.
- Optical jumpers on the switches at both ends must be connected to the ODFs at the same sequence.
- Each pair of TX and RX optical fibers between the ODFs must be cross-connected to ensure normal transmission between the optical modules at both ends.
3.5.5 There Are 8-Strand, 12-Strand, and 24-Strand MPO Fibers Available in the Market. What Are Their Differences? Which Type Is More Suitable for the CE Series Switches?
- A 40G optical module uses four channels to transmit laser and four channels to receive laser. That is, a total of eight channels are required for a 40G optical module. 8-strand and 12-strand MPO fibers use the same definition of fiber channels. Therefore, they are equivalent in functionality when connecting to 40G optical modules.
- When 100G optical modules are used, choose MPO fibers according to the following principles:
- Choose 24-strand fibers for CXP, CFP, and CFP2 modules.
- Choose 8-strand or 12-strand fibers for QSFP28 modules.
3.5.6 What Are the Pin Assignments of MPO Fibers?
NOTE: - The MPO-MPO, MPO-2*MPO, and MPO-3*MPO fibers have similar appearances except for the number of MPO connectors at the other end (1, 2, and 3 respectively).
- The MPO-4*DLC, MPO-8*DLC, MPO-10*DLC, and MPO-12*DLC fibers have similar appearances except for the number of DLC connectors at the other end (4, 8, 10, and 12 pairs respectively).

3.5.7 What Types of Power Cables Do CE12800 Series Switches Support?
AC Power Cable
NOTE: The figures provided here are for reference only and may differ from the actually delivered cables.
The AC power cables applicable to the CE12800 series switches depend on the type of power sockets used in your equipment room. Two types of AC power cables are available to suit different power sockets: PDU power cable and country-specific power cable.
- PDU power cables are delivered with a power distribution unit (PDU) with C20 straight sockets. A PDU power cable has a C19 straight female connector at one end and a C20 straight male connector at the other end, as shown in Figure 3-58.
- Country-specific power cables are delivered in compliance with standards of the destination country or region. For example, AC power cables used in China have PI angle male connectors, as shown in Figure 3-59.
If PDUs with C20 straight sockets are available in a cabinet, use PDU power cables complying with local standards.
If there is no PDU with C20 straight sockets in a cabinet, use power cables specific to the country or region where the switch is used.
Connection
An AC power cable transmits AC power to a chassis and allows maximum current of 16 A. It is connected in the following way:
- The C19 straight female connector is connected to a socket on the power distribution unit at the rear of the CE12800 chassis.
- The country-specific connector or C20 straight male connector at the other end is connected to an external power outlet.
DC Power Cable
DC power cables for a CE12800 switch include a -48 V power cable and an RTN ground cable. DC power cables with the following cross-sectional areas are available: 16 mm2, 25 mm2, and 35 mm2.
You need to cut the delivered DC power cables into appropriate lengths according to actual situations in your site and make DC power cables onsite.
Figure 3-60 shows the appearance of a DC power cable.
Figure 3-61 shows the structure of a DC power cable.
Connection
A DC power cable transmits DC power to a chassis and allows maximum current of 62 A. It is connected in the following way:
- The JG2 M6 terminal is connected to power terminals on the power distribution unit at the rear of CE12800 chassis.
- The OT M8 terminal is connected to an external power source.
High-Voltage DC PDU Power Cable
Figure 3-62 shows a high-voltage DC PDU power cable.
Connection
A high-voltage DC PDU power cable transmits 240 V high-voltage DC power to a chassis and allows maximum current of 18.5 A. It is connected in the following way:
- The C19 straight female connector is connected to a socket on the power distribution unit at the rear of the CE12800 chassis.
- The C20 straight male connector is connected as follows:
- If a high-voltage DC PDU is used, directly connect the C20 straight male connector to a socket on the high-voltage DC PDU.
- If a high-voltage DC power distribution box is used, make OT terminals for the cable. Cut the C20 straight male connector off to expose the wires in the cable. Connect the brown wire to a negative terminal on the DC power distribution box, the blue wire to a positive terminal, and the yellow-green wire to protection ground.
3.5.8 What Types of Power Cables Do CE8800&7800&6800&5800 Series Switches Support?
AC Power Cable
NOTE: The AC power cables delivered with a switch must comply with the standards used in the delivery destination. This section uses the AC power cables used in China as an example.
Two types AC power cables are applicable to the CE8800&7800&6800&5800 series switches: C13 straight female to PI straight male AC power cable and C13 straight female to C14 straight male AC power cable. The two types of AC power cables differ in the connector used to connect to power outlets. The AC power outlets must have a current rating of 10 A.
Figure 3-63 shows a C13 straight female to PI straight male AC power cable.
Figure 3-64 shows a C13 straight female to C14 straight male AC power cable.
Connection
An AC power cable transmits power to an AC power module in the chassis. It is connected in the following way:
- The C13 straight female connector is connected to the power socket on the AC power module.
- The PI/C14 male connector is connected to an external power source.
When a 600/1200 W AC&240 V DC power module uses 240 V DC power input, it must be connected to a power supply device using a C13 straight female to C14 straight male AC power cable. This power cable is connected as follows:
- The C13 straight female connector is connected to the power socket on the power module.
- The C14 straight male connector is connected to a high-voltage DC PDU. If a DC power distribution box is used, make OT or cord end terminals for the cable. Cut the C14 straight male connector off and crimp OT or cord end terminals on the bare wires. Connect the blue wire to a positive terminal on the DC power distribution box, the brown wire to a negative terminal, and the yellow-green wire to a protection ground.

3.5.12 What Are the Differences Between Power Entry Modules of CE12800 AC Chassis and DC Chassis?
The power entry module (PEM) for an AC chassis provides C20 sockets for C19 straight female connectors of AC power cables. The PEM for a DC chassis provides double DC power terminals for each power module.
3.5.13 What Types of AC Power Cables Are Applicable to CE8800&CE7800&CE6800&CE5800 Switches?
CE8800&CE7800&CE6800&CE5800 switches can receive AC power from country-specific power sockets or C13 straight female sockets. In the first mode, the switches need to use country-specific AC power cables. In the second mode, the switches need to use AC power cables with a C13 straight female connector at one end and a C14 straight male connector at the other end.
3.5.14 How Do I Identify Different Fibers from Their Appearances?
- Multimode optical fibers can be used with multimode optical modules to implement low-cost, short-distance transmission. Multimode optical fibers are classified into OM1, OM2, OM3, and OM4 types. OM1 and OM2 optical fibers are usually orange, whereas OM3 and OM4 optical fibers are usually light green. For specifications of various optical fibers, see the text printed on optical fibers.
- Single-mode optical fibers, usually G.652 fibers, can be used with single-mode optical modules to implement long-distance transmission. Single-mode optical fibers are yellow.
