Sfp Modules

• 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.

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.

A hot-pluggable Quad Small Form-factor Pluggable Plus (QSFP+) transceiver module for 40 Gigabit Ethernet (40GbE) over Multi-Mode Fiber (MMF). It utilizes 850nm VCSEL technology and an MPO/MTP connector to achieve a transmission distance of up to 300 meters on OM3 fiber or 400 meters on OM4 fiber. It is designed for high-density, intra-data center links and supports 4x10G breakout connections.

Intel E40GQSFPSR Compatible 40GBASE-SR4 QSFP+ Transceiver (and similar modules like Intel E40GQSFPSR QSFP+ SR4 Optical Transceiver) are 40 Gbps optical transceiver modules used for high-speed fiber-optic networking — commonly in data centers, enterprise switches, routers, and servers.

They are compatible replacements for Intel’s original E40GQSFPSR OEM part, meaning they function like Intel’s branded optical module but are made by third-party manufacturers that pre-program the module to work with Intel networking gear.

An Active Optical Cable (AOC) provides a high-performance, cost-effective, and low-power solution for establishing a 40 Gigabit Ethernet (40GbE) link over short-to-medium distances in data centers. It is a fixed, sealed assembly with QSFP+ connectors on both ends and utilizes embedded optical components (VCSEL and PIN photodiodes) to transmit data over multi-mode fiber (MMF). These cables are typically used for inter-rack and adjacent-rack connectivity.

TR-QQ85X-N00 40GBASE-SR4 QSFP+ Optical Transceiver

The TR-QQ85X-N00 is a high-performance 40Gbps QSFP+ optical transceiver designed for reliable, short-range data transmission over multimode fiber. It is widely used in data centers, enterprise networks, and high-performance computing environments that require fast and stable connectivity.
