When two power modules are used, they work in 1+1 backup mode to provide power for the device. In the versions earlier than V200R005C00, the AC and DC power modules cannot be configured on the same device, while in V200R005C00 version, they can be configured on the same device. Figure 2-6 shows the power supply connections of dual DC power modules. After DC power is transmitted to the PWR module, the PWR module provides -53 V output voltage, and the motherboard provides power for the entire device. 18

43 5 Cables Figure 5-5 Appearance of a single-mode SC/PC fiber jumper Select fiber jumpers according to the following rules: 1. Determine the length of fiber jumpers based on the actual cabling distance. 2. Determine the fiber type based on the optical module type. Use a multimode fiber jumper for a multimode optical module. Use a single-mode fiber jumper for a single-mode optical module. 3. Determine the optical connector type based on the interface type. Ensure that the optical connector at each end of a fiber jumper is the same type as the interface connected. Fiber Pigtail A fiber pigtail is an optical fiber that has an optical connector on one end and a length of exposed fiber at the other end. The exposed fiber can be fused to another optical fiber. Fiber pigtails are commonly used to connect optical fibers to optical fiber modules in fiber terminal boxes. (Couplers and jumpers are also used.) Figure 5-6 shows the structure of a fiber pigtail. 36

44 5 Cables Figure 5-6 Structure of a fiber pigtail Fiber pigtails are classified into single-mode and multimode fiber pigtails and are used for shortdistance connections. Optical Fiber, Optical Connector, and Fiber Adapter Optical Fibers Optical fibers are classified into single-mode fibers and multimode fibers. Single-mode fibers have a diameter of 5-10 um 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 5-3. Multimode fibers have a diameter of 50 um or 62.5 um 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. Most multimode fibers are orange, as shown in Figure 5-4. Optical Connector Optical connectors are used to connect optical fibers of the same type. Table 5-2 lists common optical connectors.

45 5 Cables NOTICE When connecting or removing a square connector, align the connector with the optical interface and do not rotate the fiber. Pay attention to the following points: To connect a fiber, align the head of the fiber jumper with the optical interface and insert the optical fiber into the interface gently. To remove a fiber, press the latch on the connector and pull the fiber out. Fiber Adapter A fiber adapter (also called a flange) is a fiber connection component. Fiber adapters are widely used in optical distribution frames (ODF), fiber transmission equipment, or optical instruments. 5.3 Network Cable Types of Network Cables Appearance and Structure 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. A straight-through cable connects a terminal, such as a computer or switch, to the network. The straight-through cable uses two RJ45 connectors, which have the same pinout. A crossover cable connects two terminals, such as computers or switches. The crossover cable uses two RJ45 connectors, which have different pinouts. NOTE Generally, a network cable is a standard unshielded network cable that uses RJ45 connectors.

56 6 Optical Modules Terms Encapsulation type Encapsulation types of optical modules include SFP, esfp, SFP+, QSFP+, XFP, as described in Table 6-1. Table 6-1 Encapsulation types of optical modules Encapsulation Type SFP esfp SFP+ QSFP+ XFP Description Small form-factor pluggable. Enhanced small form-factor pluggable. An esfp module is an SFP module that supports monitoring of voltage, temperature, bias current, transmit optical power, and receive optical power. Sometimes, esfp is called SFP. Small form-factor pluggable plus, which is SFP with a higher rate. SFP+ modules are more sensitive to electromagnetic interference (EMI) because of their higher rate. To reduce EMI, SFP+ modules have more springs than SFP modules and the cages for SFP+ modules on a card are tighter. Quad SFP+, four-channel SFP+. 10-GB small form-factor pluggable transceiver, 10GE optical module. X is the Roman numeral 10, indicating 10G. All XFP modules are 10G optical modules. Transmission distance Interface rate Center wavelength Fiber mode Modal bandwidth Maximum 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. Maximum rate of electrical signals that an optical device can transmit without bit errors. Various interface rates are defined in Ethernet standards, such as 125 Mbit/s, 1.25 Gbit/ s, Gbit/s, and Gbit/s. Wavelength measured at the midpoint of the half-amplitude line in the transmit spectrum. Mode of fibers defining based on core diameters and features of optical fibers. Optical fibers are classified into single-mode fibers and multi-mode fibers. Generally, multimode fibers have large core diameters and severe dispersion, so they transmit optical signals over short distances when working with multi-mode optical modules. Singlemode fibers have small dispersion and can transmit optical signals over long distances when working with single-mode optical modules. Bandwidth 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 an optical module. 49

57 6 Optical Modules Fiber diameter Fiber class Connector type Diameter of the core of a fiber. According to international standards for optical fibers, the diameter of a multi-mode fiber is 62.5 um or 50 um, and the diameter of a singlemode fiber is 9 um. Optical 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 classes are defined: multi-mode 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. Type 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), MPO (applicable to some of QSFP+ modules), and SC. Transmit optical power Output optical power of an optical module when it is working properly. 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 = ). 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 = ). Extinction ratio Minimum 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 SFP/eSFP Modules Appearance Figure 6-2 shows an SFP/eSFP optical module. 50
