Senko CS Fiber Optic Patch Cables

With the ever-increasing demand for network bandwidth, data centers are rapidly embracing 100Gb backbones and scaling up to even higher speeds like 200Gb and 400Gb for hyper-scale data centers. In response to this trend, a standards organization spearheaded by SENKO introduced a novel CS connector specification, aimed at augmenting the number of duplex optical links to support data rates of up to 400Gb/s. This article serves as a beginner’s guide to comprehending CS connectors and their applications in fiber patch cables.

The CS connector represents a cutting-edge advancement in high-density, very small form factor (VSFF) optical connectors, tailored for compact, high-density solutions. Offering approximately 40% space savings compared to LC and other optical connectors, CS connectors double the patch panel density achievable with LC duplex connectors. This enhanced density translates into superior cable management and performance capabilities. Featuring a user-friendly Push/Pull tab, CS connectors enhance usability in high-density applications and are available in both single-mode (SM) and multimode (MM) variants.

While traditional optical transceiver modules typically employ LC connectors, CS connector-based transceivers offer comparable functionality but with significantly higher density and lower total cost of ownership (TCO). Various high-speed optical transceivers now utilize CS connectors, including:
– 200G QSFP-DD Transceiver with 2x CS connector (2x100G)
– 400G OSFP Transceiver with 2x CS connector (2x200G)
– 800G QSFP-DD Transceiver with 2x CS connector (2x400G)
Additionally, some other 200G/400G transceivers leverage traditional LC connectors for single-mode type, MPO/MTP connectors for multimode, and parallel single-mode fiber type.

CS Connector Fiber Patch Cable Variants
– CS-CS Single Mode Fiber Patch Cable: Equipped with Senko CS connectors on both ends, this cable suits next-generation 200/400G transceiver QSFP-DD and OSFP configurations utilizing CS connectors like CWDM4, FR4, LR4, and SR2.
– LC-CS Single Mode Fiber Patch Cable: Featuring a Senko CS connector on one end and an LC connector on the other, this cable facilitates connections between CS connectors and standard LC-based patch panels, enabling versatile cabling systems with these single-mode hybrid cables.

FAQs About CS Connectors
Q1: What Are the Advantages of CS Connectors?
A: CS connectors boast higher density and durability compared to LC and SC connectors, making them an ideal choice for rugged, space-saving optical fiber connections.
Q2: What is the difference between the CS connector and SN connector?
A: The SN connector, an advanced iteration of the CS connector, offers double the density of CS and features a more compact design.
