FiberMania offers complete OEM, ODM, and private-label manufacturing services for the 400G QSFP-DD DR4 transceiver. Customization options include EEPROM coding for specific switch vendors, firmware optimization, compatibility validation, private labeling, customized pull-tabs, and branded packaging—ensuring seamless deployment and strong brand differentiation in the market.

Q1: Does this 400G DR4 module support breakout to 100G links?
A1: Yes. The module supports 4 × 100GBASE-DR1 breakout configurations when used with an MPO-12 to LC single-mode breakout cable, provided the host switch supports port splitting.

Q2: What distinguishes this 2km DR4 module from standard 500m DR4 optics?
A2: This version uses higher-performance EML lasers and optimized receiver sensitivity, enabling extended reach up to 2km while maintaining stable PAM4 signal performance.

Q3: How is power consumption kept below 10W?
A3: The module utilizes optimized EML drivers and efficient internal design to minimize power draw, helping reduce cooling requirements and improve overall data center energy efficiency.

Q4: Is the module compatible with major switch vendors?
A4: Yes. In addition to standards compliance, FiberMania provides custom EEPROM coding and firmware tuning to ensure full compatibility with leading networking platforms.

Q5: Can FiberMania support private labeling and branding?
A5: Absolutely. FiberMania specializes in private-label manufacturing, offering custom labels, branded pull-tabs, documentation, and retail packaging to support your brand strategy.
