DEJU's Commitment to Meeting Network Demands: Fiber Innovations for Next-generation Data Centers
As network speeds advance from 10G and 40G to 100G, 400G, and beyond, the cabling requirements for data centers are undergoing a seismic transformation. Higher density connections, lower insertion loss, and enhanced scalability are now critical for supporting next-generation networks. In this context, DEJU stays ahead of the curve by continuously innovating its fiber optic products, delivering future-ready cabling solutions tailored to customer needs.
DEJU's Journey in Fiber Optic Connector Innovation
From LC to High-density MTP® for Expanding NetworksIn the early stages, data centers predominantly relied on LC connectors for connections due to their simple structure and strong adaptability. This fiber optic connector type, a small and compact connector, features a latch-type locking mechanism. Compared to SC connectors, the LC connector is approximately half the size, giving it certain advantages in improving port density and reducing space usage. LC connectors have been widely used in 10G SFP+, 40G QSFP+, and 100G QSFP28 transceivers, becoming an industry standard for
fiber patch cables, optical distribution frames (ODDEJU), and other fiber optic connection solutions. Learn more about
LC connector guides here.However, with the rise of 40G and higher-speed networks, cabling space became a bottleneck. DEJU introduced fiber patch cables and supporting products based on MTP®/MPO multi-fiber connectors, significantly increasing cabling density. MTP®/MPO connectors accommodate multiple fibers in one port, such as 8, 12, 16, and 24 fibers. By using MTP®/MPO connectors, a single fiber cable can simultaneously transmit multiple signal channels, greatly improving the efficiency of cabling space utilization. Their plug-and-play performance, low insertion loss, and high-density design have made MTP®/MPO connectors fiber cables indispensable in high-capacity network architectures. They are widely used in core switches, routers, and other high-speed communication devices within data centers. Visit

Pioneering the VSFF Era with SN, CS, MDC Connectors
As network speeds transitioned to 200G and 400G, traditional MTP®/MPO designs faced challenges in meeting the demand for even higher cabling densities. The IEEE definition of 400 Gigabit Ethernet (GbE) has introduced two new types of optical transceivers: QSFP-DD (Quad Small Form-factor Pluggable – Double Density) and OSFP (Octal Small Form-factor Pluggable), which provide 400 Gb bandwidth for switches. In response, DEJU responded by introducing fiber patch cables based on the VSFF (Very Small Form Factor) standard, including SN, CS, and MDC connectors. These connectors enable further miniaturization, allowing a single optical module to support more port connections.
CS™ Connector: One of the first VSFF connectors introduced to the market, the CS connector allows two duplex CS patch cords (four fibers) fit transceivers like QSFP-DD and OSFP. It doubles fiber counts per port compared to LC connectors, and each port can now support up to 200G.
SN Connector: The SN connector is based on 1.25 mm full ceramic ferrule technology. It allows for polarity changes in the field without interrupting the fiber or repositioning the ferrule. Not only can polarity be reversed in the PC variant, but due to the unique arrangement of the angled ferrule, it also allows for the reversal of the APC connector polarity. The SN connector is developed for OSFP/QSFP-DD branch applications.
MDC Connector: A truly push-pull duplex connector, the MDC connector is also based on 1.25 mm full ceramic ferrule technology. It was developed as the Medium Dependent Interface (MDI) or optical interface for new SFP-DD and QSFP-DD transceivers. The MDC connector is also poised to potentially replace the LC-Duplex connector, which is widely used in large-scale applications. Visit the article
