Brazilian quote for transimpedance amplifier QSFP-DD

For a Brazilian quote on a QSFP-DD compatible transimpedance amplifier, you can contact local suppliers like Padtec or international vendors such as fJscaler, who provide high-speed TIAs suitable for 400G optical modules.

Local Supplier Options in Brazil

• Padtec offers QSFP-DD 400G modules and coherent optical solutions compatible with major switches and routers. While they primarily provide complete transceivers, they can advise on compatible TIAs or integrate them into high-density optical modules for regional and long-haul networks .
• Cisco Brazil distributes QSFP-DD 400G Digital Coherent Optics modules, including ZR and ZR+ variants. Cisco partners in Brazil can provide pricing and technical support for modules that include integrated TIAs .

International Vendors with Brazilian Support

• fJscaler Inc. manufactures high-frequency, low-power linear TIAs and drivers suitable for QSFP-DD and OSFP form factors. Their dual-channel 64GBd differential linear TIA includes variable gain amplifiers and output buffers, with low power dissipation (~495mW), making it ideal for 100G–400G coherent optics applications . Brazilian distributors or local representatives can provide quotes and shipping options.
• MACOM offers the MATA-40734/36 Quad Linear TIA, supporting 227Gbps PAM4 optical links. This TIA features low power consumption (~300mW) and I2C control for gain, bandwidth, and signal monitoring, suitable for integration into QSFP-DD modules .

How to Obtain a Quote in Brazil

1. Contact Padtec Brazil via their website or sales team to request a quote for QSFP-DD modules or compatible TIAs.
2. Reach out to Cisco Brazil partners for pricing on QSFP-DD 400G ZR/ZR+ modules, which include integrated TIAs.
3. Request a quote from fJscaler through their website or authorized Brazilian distributors for standalone TIAs suitable for QSFP-DD modules.
4. Specify technical requirements such as data rate (100G–400G), modulation format (PAM4 or coherent), and power constraints to ensure the quote matches your application.

By contacting these suppliers, you can obtain official Brazilian pricing, lead times, and technical support for transimpedance amplifiers compatible with QSFP-DD 400G optical modules.
