The 100G QSFP28 modules have emerged as the industry’s go-to 100G transceivers, thanks to their cost-effective production, compact size, and impressive performance capabilities. This article delves into the specifications, various versions, and key features that have solidified the QSFP28’s position as a market leader in high-speed networking solutions.
Overview of 100G QSFP28 Modules
The 100G QSFP28 transceivers have revolutionized the networking landscape, offering unparalleled data transmission speeds and efficiency. Their popularity can be attributed to several factors, including their low production costs, compact form factor, and high output. In this article, we will explore the specifications, different versions, and the unique details that have made the QSFP28 a market giant.
10Gtek’s 100G QSFP28 Module Offerings
10Gtek specializes in manufacturing a range of 100G QSFP28 modules, including SR4, LR4, CWDM4, and IR4 PSM. Let’s examine the distinct advantages and applications of each module.
QSFP28 SR4
The QSFP28 SR4 module, often considered the entry-level option in the 100G transceiver family, offers remarkable value without compromising on performance. Despite its “short range” designation, the SR4 delivers the same 100Gbps data transfer speed as its counterparts. Utilizing an MTP/MPO interface, it employs multi-mode fiber cables for short-distance connections. Both the IR4 PSM and SR4 rely on a 12-fiber MTP/MPO patch cable. The SR4’s main appeal lies in its cost-effective price point, making it an ideal choice for budget-conscious network administrators seeking high-speed connectivity without breaking the bank. Like all 10Gtek modules, the SR4 undergoes rigorous testing on Cisco and Accton devices to ensure seamless integration and optimal performance. 10Gtek maintains a steady stock of SR4 modules, ensuring prompt delivery to meet customer demands.
QSFP28 LR4
At the pinnacle of the QSFP28 product line, the LR4 module represents the epitome of performance and versatility. As a full-duplex LC module, it combines both transmit and receive functionalities within a single compact unit. On the transmit side, the LR4 boasts four lanes of high-end optical signals, each capable of transmitting data at an astonishing 25Gbps. On the receive side, it features a fully integrated de-multiplexer that efficiently de-multiplexes data streams, converting them into CAUI-4 electrical output. With a maximum link length of 10km, the LR4 operates over a single-mode fiber cable with a duplex LC connector, making it suitable for long-haul data transmission. All 10Gtek LR4 modules are thoroughly tested on Cisco and Accton devices, ensuring compatibility and reliability for your networking infrastructure. As the flagship offering in 100G transceivers, the LR4 is always available in-stock, with lightning-fast delivery times to support your network upgrades and expansions.
QSFP28 CWDM4
Complementing the LR4, the CWDM4 is another full-duplex LC module that delivers exceptional performance. Like the LR4, it transmits data at over 100Gbps through its four lanes of high-end optical transmitters and utilizes a fully integrated de-multiplexer for efficient data reception. A key advantage of both the LR4 and CWDM4 modules is the ease of upgrading existing network infrastructure. They operate on standard single-mode duplex LC patch cables, eliminating the need to replace all existing fiber patch cables, which saves significant costs, reduces headaches associated with cable management, and minimizes downtime during upgrades. The removable “push-pull” tabs also help save space. As with all 10Gtek modules, the CWDM4 undergoes comprehensive testing on Cisco and Accton devices. The primary distinction between the CWDM4 and LR4 is their maximum link length, with the CWDM4 supporting distances up to 2km, making it well-suited for most common networking demands.
QSFP28 IR4 PSM
Shifting from duplex LC modules, we have the IR4 Parallel Single Mode Transceiver. The IR4 features an MTP/MPO interface with four independent full-duplex lanes, offering high-speed data transmission at over 25Gbps per transmit lane. It also incorporates parallel optical receiver lanes to convert input signals. Compatible with Common Mode Logic (CML) levels, the IR4 PSM does not sacrifice distance, providing a range of up to 2km. Utilizing single-mode fiber cables, it is capable of long-distance communication. Like all 10Gtek modules, the IR4 PSM is fully tested on Cisco and Accton devices, ensuring reliable performance. The IR4 PSM is an excellent choice for customers who wish to maintain high-quality speed and distance without upgrading to more expensive LC modules.
Conclusion:
The 100G QSFP28 transceivers from 10Gtek offer a diverse range of options tailored to various networking needs. From the cost-effective SR4 to the high-performance LR4, and the versatile CWDM4 and IR4 PSM, these modules provide the perfect solution for businesses seeking to enhance their network infrastructure. With their advanced technology, reliable performance, and compatibility with leading networking devices, 10Gtek’s 100G QSFP28 modules are the ideal choice for future-proofing your network and ensuring seamless data transmission in today’s fast-paced digital landscape.
