FS (FS.COM / Fiberstore) Hardware Identification & Product Part Numbering

FS (FS.COM Inc., originally founded as Fiberstore; headquartered in Shenzhen, China with international operating subsidiaries in the United States, Germany, the United Kingdom, Singapore, Australia, and Japan) is a globally recognized technology provider of high-speed optical communications, data

center networking switches, and enterprise fiber infrastructure.

To verify equipment compatibility and obtain an official B2B commercial offer, please provide the manufacturer part number (SKU, e.g. S5860-20SQ, S8550-16Q8C, QSFP28-100G-SR4, DAC-100G-1M, FMU-D402160-M).

When inquiring about optical transceivers or DAC cables, specify the target host equipment vendor and model to ensure exact EEPROM firmware compatibility coding.

For replacement power supplies (PSUs), fan tray modules, or expansion line cards, attaching an equipment nameplate photo or CLI hardware inventory output (show inventory) ensures 100% bill-of-materials verification.

FS Data Center & AI Cloud Networking Switches: S5860, S5850, and S8550 Series

FS data center switch families including S5860, S5850, S8050, S8550, NC8200, and NC8400 series leverage industry-standard Broadcom switching silicon architectures to achieve ultra-low port-to-port latency and generous packet buffer headroom.

They provide high-density non-blocking L2+/L3 line-rate performance with 10G/25G Top-of-Rack access ports and 100G/400G/800G Spine uplinks.

Hardware-accelerated EVPN-VXLAN protocol support enables scalable multi-tenant overlay network virtualization across distributed data centers.

For high-performance computing (HPC) and artificial intelligence (AI) training clusters, lossless RoCEv2 (RDMA over Converged Ethernet) with PFC and ECN mechanisms guarantees zero packet loss and predictable transmission latencies.

We supply complete data center switches, redundant hot-swappable AC/DC power supply modules, and variable-speed fan trays with reversible front-to-back or back-to-front airflow.

FS Enterprise Campus Managed & PoE+ Access Switches: S3900 and S3910 Series

The S3900, S3910, S3410, and S3150 enterprise switch series deliver reliable wire-speed connectivity for enterprise campus LANs, office networks, and converged surveillance deployments.

Models support IEEE 802.3af/at/bt PoE, PoE+, and PoE++ standards with power budgets up to 740W to power Wi-Fi 6/7 access points, PTZ cameras, and VoIP phones.

Hardware stacking enables up to 8 switches to operate as a single virtual management entity under one IP address, featuring cross-stack Link Aggregation (LACP) and resilient failover. Enterprise protocols including STP/RSTP/MSTP and ERPS prevent network loops while maintaining rapid convergence.

We supply 8-port, 24-port, and 48-port switch configurations, optical uplink modules, and console management accessories.

FS IES Ruggedized Industrial DIN-Rail Ethernet Switches for Harsh Environments

The FS IES3100 and IES5100 industrial Ethernet switch families are engineered for reliable 24/7 mission-critical operations across extreme temperature swings, transportation systems, utility substations, mining facilities, and outdoor roadside cabinets.

Heavy-duty aluminum IP40 enclosures support standard 35mm DIN-rail or wall mounting.

All models operate across an extended temperature range of -40°C to +75°C utilizing fanless passive convection cooling. Dual redundant 12–48V DC power inputs with reverse polarity protection and an integrated fault relay alarm contact ensure continuous communications uptime.

Support for ITU-T G.8032 ERPS industrial multi-ring topologies guarantees rapid sub-20ms network failover and self-healing.

FS Optical Transceivers: SFP+, SFP28, QSFP28, 400G QSFP-DD & Vendor Compatibility Coding

FS optical transceiver modules cover mainstream transmission speeds and form-factors: 1G SFP, 10G SFP+, 25G SFP28, 40G QSFP+, 100G QSFP28, 400G QSFP-DD, and 800G OSFP. All modules comply with MSA (Multi-Source Agreement) standards and carry international CE, FCC, and RoHS certifications.

A standout capability of FS transceivers is custom EEPROM firmware compatibility coding for all major networking brands: Cisco, Juniper, Arista, HPE, Dell, Extreme, Huawei, and Brocade. This enables seamless plug-and-play operation without host CLI warnings or port shutdown errors.

Integrated Digital Optical Monitoring (DOM/DDM) provides real-time monitoring of transmit/receive optical power, laser bias current, module operating voltage, and internal temperature.

FS Direct Attach Copper (DAC) Cables and Active Optical Cable (AOC) Assemblies

For high-density intra-rack and inter-rack Top-of-Rack server-to-switch interconnects, FS provides Direct Attach Twinax Copper (DAC) cables and Active Optical Cables (AOC) spanning transmission rates from 10G up to 800G.

Passive copper DAC cables from 0.5 to 5 meters offer maximum energy efficiency: zero transceiver power consumption, ultra-low propagation latency (<5 ns), and cost savings compared to optical transceivers. Active AOC cables up to 100 meters deliver lightweight, flexible cabling in tight pathways.

Hybrid breakout cable assemblies (40G QSFP+ to 4x10G SFP+, 100G QSFP28 to 4x25G SFP28, 400G to 4x100G) allow direct connectivity between disparate interface generations.

FS CWDM/DWDM Optical Transport Systems & FMT Modular Wavelength Multiplexing

FS CWDM and DWDM wavelength division multiplexing systems and the FMT (Fiber Multi-Service Transport) modular chassis platform enable multi-terabit capacity scaling over existing dark fiber lines without trenching new fiber routes.

Passive DWDM Mux/Demux panels support 8 to 80 channels over ITU-T 100 GHz and 50 GHz grids. Erbium Doped Fiber Amplifiers (EDFA) across Booster (BA), Line Amplifier (LA), and Pre-Amplifier (PA) configurations enable unrepeatered spans exceeding 120 km.

Optical Line Protection (OLP) modules execute automated sub-5ms path switching to secondary fiber routes during optical link degradation or fiber cuts.
