Winsonic WSFP-C8-S35-20Di-F Gigabit Ethernet SFP Transceiver
Overview
Winsonic WSFP-C8-S35-20Di-F is an industrial-grade Small Form-Factor Pluggable transceiver engineered by Winsonic for Gigabit Ethernet networks that must keep running in harsh electrical, thermal and vibration environments. Built around a uncooled 1310nm FP transmitter paired with a high sensitivity PIN receiver, the Winsonic WSFP-C8-S35-20Di-F converts electrical Ethernet signals into optical pulses carried over SMF fibre, supporting the 1000BASE-BX10 and Fibre Channel 1GFC standard over links of up to 20km. As a hot-swappable module it drops directly into any SFP-compatible cage on a Winsonic router, industrial switch or third-party network equipment, letting network designers mix copper and fibre ports on a port-by-port, pay-as-you-populate basis.
As the official authorized partner and exclusive regional representative for Winsonic, Seven Star LLC proudly supplies the Winsonic WSFP-C8-S35-20Di-F to system integrators, data centre operators and industrial network builders across Oman, Muscat and the wider GCC, backed by local technical support. Seven Star LLC deploys the WSFP-C8-S35-20Di-F in fibre backbones, ring-topology industrial networks and remote monitoring links throughout the Sultanate of Oman, from the Sohar and Salalah free zones to Muscat metro-area utility networks.
Operating Principle
Inside the WSFP-C8-S35-20Di-F, the uncooled 1310nm FP laser diode is directly modulated by the incoming electrical Ethernet or SONET/SDH bitstream and launches the corresponding optical pulses into the fibre through a Simplex LC (BiDi) interface. On the receive path, the high sensitivity PIN receiver converts the arriving light back into an electrical signal with enough sensitivity margin to close the full 20km link budget over SMF fibre without external amplification, making the Winsonic WSFP-C8-S35-20Di-F engineered as a bidirectional (BiDi) transceiver that carries both transmit and receive signals over a single fibre strand, halving fibre-core requirements on long single-mode runs.
Because the conversion is entirely optical, the link carries no electrical continuity between the two connected sites, which removes ground-loop risk and gives complete immunity to electromagnetic interference from nearby VFDs, motors and switchgear — a critical property in the industrial and petrochemical facilities Seven Star LLC serves across the GCC. Digital Optical Monitoring (DOM) circuitry continuously reports transmit power, receive power, laser bias current, supply voltage and module temperature back to the host device, giving network engineers real-time visibility into fibre-link health long before a failure occurs.
Engineering Design of the Winsonic WSFP-C8-S35-20Di-F
The Winsonic WSFP-C8-S35-20Di-F is housed in a metal SFP shell with an integrated latch/bail-clip release mechanism, EMI shielding fingers and a die-cast body that dissipates heat from the laser and receiver ICs even in enclosed, fan-cooled switch chassis. The Simplex LC (BiDi) optical interface is factory-aligned and dust-capped, and the module is qualified to operate reliably across the extended temperature range expected of Winsonic’s industrial networking line, well beyond the 0–70°C rating of commercial-grade optics.
Electrically the WSFP-C8-S35-20Di-F follows the MSA-compliant SFP/SFP+ pinout, so it is recognised automatically by the host device’s I2C-based module-identification interface with no manual configuration, and it can be swapped in the field in seconds without powering down the entire chassis. This plug-and-play design, combined with DOM diagnostics exposed over the same I2C bus, means field technicians can verify a suspect optical link with a laptop and the switch’s management interface rather than dispatching a technician with an optical power meter.
Key Features
The Winsonic WSFP-C8-S35-20Di-F combines optical performance with the mechanical and diagnostic robustness industrial buyers expect from an authorized-partner-supplied module. Key characteristics include:
- uncooled 1310nm FP transmitter paired with a high sensitivity PIN receiver for a stable, temperature-tolerant optical budget.
- Supports 1000BASE-BX10 and Fibre Channel 1GFC over SMF fibre up to 20km.
- Simplex LC (BiDi) optical connector for straightforward patching into existing fibre infrastructure.
- Hot-swappable MSA-compliant SFP form factor, recognised automatically with no driver installation.
- Digital Optical Monitoring (DOM) for real-time transmit/receive power, bias current and temperature reporting.
- Metal shielded housing for EMI immunity and mechanical durability in panel-mounted switches and routers.
- Interoperable across Winsonic’s router, gateway and industrial switch product lines for mixed copper/fibre deployments.
- Supplied through Seven Star LLC, the authorized partner for Oman and the GCC.
Industrial Applications
Network designers specify the Winsonic WSFP-C8-S35-20Di-F wherever a Gigabit Ethernet link must run further than copper allows, or must be immune to the electrical noise typical of an industrial plant. Typical deployments include fibre backbones between control rooms and remote I/O cabinets in oil and gas facilities, ring-topology Ethernet networks for water and wastewater treatment plants, CCTV and access-control backhaul for large commercial and hospitality campuses, and inter-building links on district cooling and desalination sites where copper runs would exceed the 100m Ethernet limit.
As the officially authorized partner for Winsonic, Seven Star LLC distributes the WSFP-C8-S35-20Di-F to system integrators building fibre-based industrial Ethernet, smart building and utility SCADA networks throughout Oman and the GCC, including projects in the Sohar and Salalah economic zones, Muscat’s hospital and hotel developments, and oilfield telemetry networks that depend on long-haul fibre for reliability.
