• Model: 100GBASE-LR4 QSFP28 Receive-Only

• Speed & Reach: $100$ Gbps over Single-Mode Fiber (SMF) up to 10 kilometers ($10$ km).

• Function: It is installed in a network device port that only needs to listen for incoming $100$ Gbps traffic and does not need to send any return data.

• Primary Purpose: Optical Monitoring, Troubleshooting, and Traffic Capture. It is used for passive, non-intrusive monitoring of a live fiber link, often in conjunction with fiber tapping or splitting devices.

A hot-pluggable CFP2 (C Form-factor Pluggable 2) transceiver module designed for 100 Gigabit Ethernet (100GbE) and OTU4 applications. It operates over Single-Mode Fiber (SMF) using CWDM (Coarse Wavelength Division Multiplexing) technology in the 1310 nm band to achieve a reliable transmission distance of up to 10 kilometers (10KM). This module is half the size of the original CFP, offering higher port density and lower power consumption.

This is a high-performance, hot-pluggable Quad Small Form-factor Pluggable Plus (QSFP+) transceiver designed for 40 Gigabit Ethernet (40GbE) and high-speed enterprise backbone and Data Center Interconnect (DCI) applications. The 40GBASE-LR4 specification enables transmission up to 10 kilometers (6.2 miles) over standard Single-Mode Fiber (SMF) using Duplex LC connectors

A hot-pluggable Quad Small Form-factor Pluggable Plus (QSFP+) transceiver module designed for 40 Gigabit Ethernet (40GbE) over Multi-Mode Fiber (MMF). It uses 850nm VCSEL technology to deliver short-range, high-speed connectivity, typically reaching 300 meters over OM3 fiber. It is often used for high-density, intra-data center links and supports 4x10G breakout applications.
