4.2.4 How to View Optical Module Parameters

Viewing the Hardware Description
If you know the model or type of an optical module, you can view the section "Pluggable Modules
for Interfaces" in the Hardware Description to look up parameters of the optical module,
including the center wavelength, transmission distance, fiber types supported, receive optical
power, and transmit optical power.
Using a Command
If an optical module is installed in a running switch, you can run the display transceiver
command to view parameters of the optical module, including the center wavelength,
transmission distance, fiber types supported, receive optical power, and transmit optical power.

4.3 Understanding Copper Modules

Unlike optical modules, copper modules do not perform electrical-optical conversion. When
two optical interfaces have copper modules installed, the interfaces can be connected using a
copper cable. Currently, Huawei offers only GE copper modules with RJ45 interfaces. GE
copper modules work with Category 5 network cables, comply with 1000BASE-T (IEEE
802.3ab), and support a maximum transmission distance of 100 m.

4.4 Models and Parameters

4.4.1 SFP/eSFP Modules

Issue 07 (2014-10-25)
Maximum 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.
Wavelength measured at the midpoint of the half-amplitude line in the transmit spectrum.
Two connected optical modules must have the same center wavelength.
Multi-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.
