When two power modules are used, they work in 1+1 backup mode to provide power for the device. An AC power module and a DC power module cannot be configured at the same time. Figure 3-3 shows the power supply mode 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.

Encapsulation type Encapsulation type of an optical module. Encapsulation types of optical modules include eSFP, SFP+, as described in Table 7-1. Table 7-1 Encapsulation types of optical modules Encapsul ation Type eSFP Description Optical Module
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, SFP with a higher rate. SFP+ modules are more sensitive to electromagnetic interference (EMI) because they have a higher rate. To reduce EMI, SFP+ modules have more springs than SFP modules and the cages for SFP+ modules on a card are tighter.

Transmission distance
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. The interface rates defined in Ethernet standards include 125 Mbit/s, 1.25 Gbit/s, 10.3125 Gbit/s, and 41.25 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 multimode fibers. Generally, multimode fibers have large core diameters and severe dispersion, so they transmit optical signals over short distances when working with multimode optical modules. Single-mode 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. Pattern bandwidth reflects spectrum characteristics of an optical module.

Fiber diameter
Diameter 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. 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: 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. 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), SC, and MPO (applicable to 150 m QSFP+ and CXP modules).

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 = 10 to 12).
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 to 12). 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 1.
