QSFP+ Module
=================
Introduktion
——————
The QSFP+ (Quad Small Form-factor Pluggable Plus) module is a high-speed transceiver used for data communication applications. It is widely deployed in data centers and networking equipment to enable the transmission of large volumes of data over short distances. This article will provide an in-depth explanation of the QSFP+ module and its various aspects.
Types of QSFP+ Modules
——————-
There are several variations of QSFP+ modules available in the market, catering to different data communication requirements. These include:
1. QSFP+ SR (Short-Reach): This module is designed for short-distance data transmission up to 100 meters using multi-mode fiber-optic cables. It operates at a data rate of up to 40 Gbps per channel.
2. QSFP+ LR (Long-Reach): The LR module is used for long-distance data transmission of up to 10 kilometers using single-mode fiber-optic cables. It supports data rates of up to 40 Gbps per channel.
3. QSFP+ ER (Extended-Reach): The ER module is capable of transmitting data over extended distances up to 30 kilometers using single-mode fiber-optic cables. It also operates at a data rate of 40 Gbps per channel.
4. QSFP+ AOC (Active Optical Cable): An AOC is a QSFP+ module integrated with fiber-optic cables. It provides a cost-effective solution for short-range data transmission up to 100 meters without the need for separate cables.
Features and Specifications
—————————-
The QSFP+ module offers several features and specifications that make it an ideal choice for high-speed data transmission:
