Technical Features & Performance

Proactive DDM / DOM Monitoring

Compliant with the SFF-8472 standard, our SFP transceivers support integrated Digital Diagnostic Monitoring (DDM), also known as DOM. This telemetry bus tracks real-time operational parameters directly through your system console to assist in predictive link maintenance:

• Optical Transmitter (TX) Power

• Optical Receiver (RX) Power

• Laser Bias Current

• Internal Module Temperature

• Supply Voltage

Hardened Industrial-Grade Availability

For harsh environments, we also offer industrial-grade SFP modules designed to withstand challenging conditions with specialized shielding and thermal engineering:

• Extended Operational Temperature: Rated for continuous performance from -40°C to 85°C.

• Enhanced Thermal Management: Zinc-alloy housings engineered to maximize heat dissipation and component longevity.

• Electromagnetic Protection: Reinforced internal shielding to mitigate high EMI on automation and factory floors.

Targeted Network Applications

• Enterprise Data Centers: Reliable high-density server-to-switch and switch-to-switch clustering.

• Telecom Backhaul: Long-distance transport links for metropolitan and cross-regional networks.

• Industrial Automation: Hardened network infrastructure for outdoor security, utility grids, and transportation hubs.

• Storage Area Networks (SAN): Low-latency, high-throughput Fibre Channel connectivity for enterprise storage arrays.

FAQ

1.What is an SFP transceiver?

An SFP (Small Form-factor Pluggable) transceiver is a compact, hot-pluggable network interface module used for data communications. It bridges the hardware motherboard of devices like switches and routers with fiber optic or copper networking cables.

2. What is the difference between SFP and SFP+?

The primary difference is the supported data rate. A standard SFP module typically handles speeds up to 1Gbps, while an SFP+ (SFP Plus) transceiver is an enhanced form factor designed to support data rates of 10Gbps and higher.

3.What is the difference between SFP and SFP28?

SFP28 is an evolved version of SFP+, specifically optimized for 25Gbps per channel lanes. While sharing the same structural dimensions, SFP28 transceivers utilize upgraded electrical routing and clocking to handle higher speeds, commonly deployed in 25G ToR switching and 5G mobile fronthaul applications.

4. Can I use an SFP+ module in a standard SFP port?

In most standard networking configurations, an SFP+ transceiver cannot operate in a 1G SFP-only port because the slot lacks the necessary electrical architecture to support 10G speeds. However, a 1G SFP module can often work in a 10G SFP+ port if the host switch software explicitly allows multi-rate down-negotiation.

5. What is a BiDi SFP transceiver?

A BiDi (Bi-Directional) SFP transceiver utilizes Wavelength-Division Multiplexing (WDM) to transmit and receive data simultaneously over a single strand of single-mode fiber. By pairing differing wavelengths (such as TX1310nm/RX1550nm), BiDi modules allow engineers to double fiber capacity using existing cable deployments.

6. How do I choose between single-mode and multimode SFP modules?

Selection is dictated by your fiber cable infrastructure and distance requirements. Multimode SFP modules (typically 850nm) operate over OM3/OM4 cabling and are optimized for short-range deployments under 550 meters. Single-mode SFP modules (typically 1310nm/1550nm) operate over OS2 cabling and are engineered for long-haul distances up to 10km, 40km, or 80km.

7. Which SFP module is best for a 10km transmission distance?

For a standard 10km link budget, an industry-standard 1310nm single-mode transceiver is recommended. For 1G links, this corresponds to a 1000BASE-LX SFP; for 10G links, it corresponds to a 10GBASE-LR SFP+ module.

8. What does DDM mean in SFP modules?

DDM stands for Digital Diagnostic Monitoring, also known as DOM. It is a feature that allows network operators to read real-time diagnostic telemetry, including optical output/input power, operating temperature, and laser bias current, helping to avoid unpredicted link degradation.
