Network Switch:
Cisco Module GLC-TE
The Cisco Module GLC-TE is a copper-based Gigabit Ethernet SFP transceiver, not a fiber optic module. It provides 1000BASE-T connectivity over standard twisted-pair copper cables (Cat5e or higher) with an RJ-45 connector, supporting speeds of 10/100/1000Mbps and distances up to 100 meters.
Cisco PVDM3-32 Module
The Cisco PVDM3-32 is a high-density voice and video DSP module that provides digital signal processor (DSP) resources for voice and video applications on Cisco Integrated Services Routers (ISRs). The full name of PVDM3-32 is PVDM = Packet Voice Digital Signal Module, 3 = Third generation and 32 = 32 channels of DSP resources. Here are some key points about the Cisco PVDM3-32 Module:
Cisco QSFP-40G-LR4 Module
Cisco QSFP-40G-LR4 Module is a optic fiber module that connects network devices with 40Gbps speed. This Cisco module uses optical fiber technology for sending and receiving data remotely. Cisco QSFP-40G-LR4 Module uses for long distance and connecting devices such as network router and other network equipment together.
Cisco QSFP-40G-LR4-S Module
Cisco QSFP-40G-LR4-S Module can transmit data at the highest speed of 44.6Gbps up to 10 km over SMF. This network module is fully compliant with QSFP+ MSA, IEEE 802.3ba 40GBASE-LR4, OTU3 C4S1-2D1 standards, and also fully supports OTN OTU3, 40G Ethernet, Infiniband, Fiber Channel, SATA/SAS3, MSA Compliant protocols.

Cisco VIC2-4FXO Voice Interface Card
The Cisco VIC2-4FXO is a Voice Interface Card (VIC) designed for Cisco Integrated Services Routers (ISRs). Every parts of Cisco VIC2-4FXO mean; VIC = Voice Interface Card, FXO = Foreign Exchange Office (a type of analog voice port) and 4FXO = 4 FXO ports on the card. It allows a router to connect to the Public Switched Telephone Network (PSTN) using analog phone lines (like traditional copper telephone lines from your phone company)
