CIF prices for DML-based optical receivers vary widely depending on wavelength, data rate, and supplier, typically ranging from a few hundred to over a thousand USD per module.

Overview of DML Optical Receivers

Directly Modulated Lasers (DMLs) are commonly used in short-reach optical links due to their low cost, small form factor, and low power consumption . Optical receivers paired with DMLs are designed to detect the modulated optical signal and convert it into electrical signals for further processing. Key specifications affecting price include:

• Wavelength: Common options are 1270–1550 nm, with 1310 nm and 1550 nm widely used in telecom and data center applications .
• Data Rate: Modules support rates from 10G to 25G or higher, with higher-speed modules generally costing more .
• Form Factor: QSFP28, SFP28, and OSFP modules are standard; smaller or specialized modules may have higher unit costs .
• Modulation Bandwidth: DMLs typically operate up to 4 GHz for low-speed modules, while high-speed modules require advanced driver electronics .

Typical Pricing

While exact CIF prices depend on supplier, order volume, and shipping terms, general ranges are:

• Low-speed DML modules (10G, 1270–1550 nm): $200–$500 per unit .
• High-speed DML modules (25G, 1310–1550 nm, QSFP28/OSFP): $800–$1,200 per unit .
• Custom or high-power modules: Prices can exceed $1,500 depending on temperature range, polarization-maintaining fiber, or integrated TEC stabilization .

Suppliers and References

• Optilab: Offers DML modules with polarization-maintaining fiber output, TEC stabilization, and remote control via RS485. Pricing is available upon request .
• Lumentum: Manufactures InP DMLs with multiple wavelengths and data rates, including bare die and packaged modules for 10G and 25G applications .

Recommendation

To obtain an accurate CIF price, it is best to contact suppliers directly with your required specifications (wavelength, data rate, form factor, and quantity). This ensures the quote includes shipping, insurance, and any applicable import duties. For bulk orders, suppliers may offer volume discounts or customized modules tailored to your system requirements.
