Product Overview
CS Fiber Patch Cords are high-performance fiber optic assemblies designed for next-generation 200G and 400G data center networks. Built around the miniature CS connector, these patch cords offer compact size, low insertion loss, and high return loss comparable to standard LC connectors, making them ideal for high-density environments.
The CS connector features a 1.25 mm duo cylindrical spring-loaded ferrule with a push-pull coupling mechanism, ensuring easy insertion and removal in dense patch panels. Its optical alignment mechanism uses either a rigid or resilient sleeve for precise connection. CS Fiber Patch Cords are fully compatible with QSFP-DD and OSFP transceivers, supporting 2x100G or 200G CWDM4 links.
Widely adopted in hyperscale data centers, cloud computing infrastructure, and AI/HPC clusters, CS Fiber Patch Cords optimize fiber routing, minimize footprint, and improve port density. Spring Optical manufactures these assemblies under strict quality control and in compliance with TIA, IEC, and YD/T standards. They support multiple fiber types including OS2, OM1, OM2, OM3, OM4, and OM5, meeting the requirements of high-speed Ethernet and Fiber Channel applications.

How to Choose the Right Fiber for Your Optical Network
Selecting the appropriate fiber type is critical for achieving optimal performance in 200G/400G data center networks. Spring Optical CS Fiber Patch Cords are compatible with multiple fiber types, each suited for specific applications and transmission distances:
OS2 Single-Mode Fiber (9/125 μm) – Ideal for 1G, 10G, 40G, 100G, and 400G Ethernet connections. Supports up to 10 km at 1310 nm or 40 km at 1550 nm.
OM1 Multimode Fiber (62.5/125 μm) – Suitable for 100/1000BASE-SX transceivers in Fast Ethernet, Gigabit Ethernet, and Fiber Channel applications.
OM2 Multimode Fiber (50/125 μm) – Supports 1000BASE-SX and SFP transceivers for Gigabit Ethernet and Fiber Channel.
OM3 Multimode Fiber (50/125 μm, Laser Optimized) – Preferred for 10G SR, 10G LRM, SFP+ transceivers, supporting 10G, 40G, and 100G Ethernet connections.
OM4 Multimode Fiber (50/125 μm, Laser Optimized) – Ideal for 40G BIDI SR, 10G SR, QSFP+, and SFP+ transceivers, preferred for 40G/100G Ethernet.
OM5 Wideband Multimode Fiber (50/125 μm) – Optimized for multi-wavelength SWDM applications (850–950 nm), reducing fiber count by four times for 40G and 100G links while remaining fully backward compatible with OM4 networks. RoHS compliant, optically tested for insertion loss.
