QSFP-100G-LR4 Transceiver Modules

QSFP LR4 is a type of hot-pluggable optical transceiver for 100Gbps Ethernet. 'QSFP' stands for Quad Small Form-factor Pluggable, indicating its compact size. 'LR4' signifies 'Long Reach' using four wavelengths, capable of transmitting data up to 10 kilometers over single-mode fiber, ideal for data center interconnects.

100GBASE-LR4 is the official IEEE standard for 100 Gigabit Ethernet transmission over single-mode fiber. It specifies using four separate 25Gbps wavelengths multiplexed together to achieve a total of 100Gbps. The standard defines a maximum transmission distance of 10 kilometers, making it a popular choice for campus and metro networks.

Yes, when sourced from a reputable vendor like Terabit Systems. Every module undergoes a rigorous 5-step quality assurance and testing process to ensure it meets or exceeds original manufacturer specifications. We back our refurbished transceivers with a comprehensive warranty for your peace of mind and network stability.

QSFP-100G-LR4 transceivers are designed exclusively for use with single-mode fiber (SMF) optic cables. They typically use a duplex LC connector to interface with the SMF patch cords. This setup is essential for achieving the maximum reliable transmission distance of up to 10 kilometers specified by the LR4 standard.

It is not recommended. Network equipment manufacturers often code their transceivers to work only with their own hardware. A Juniper-branded module is designed and tested for optimal performance in Juniper devices like the QFX Series. Using it in other brands may lead to compatibility issues or a complete failure to function.

The '100G' signifies the module's data rate, which is an impressive 100 Gigabits per second (Gbps). This high-bandwidth capacity is critical for modern network backbones, data centers, and service providers to handle the massive data traffic generated by cloud computing, video streaming, and other demanding applications.
