QSFP Cages & Connectors for 40G Optical Transceiver Modules

QSFP cages and QSFP connectors are the mechanical and electrical foundation for 40 Gigabit optical transceivers. A QSFP cage secures the QSFP module, provides EMI shielding, and supports thermal requirements, while a QSFP connector ensures accurate alignment and low-loss mating for 40G signal paths.

In 40G switches, aggregation routers, and storage arrays, properly designed 40G QSFP cages help maintain signal integrity and offer robust mechanical life. Complementary 40G QSFP connectors enable repeated hot-plug cycles with minimal performance degradation.

Trxcom offers single- and multi-port QSFP cages with optimized airflow and EMI springs, plus precision QSFP connectors with configurable plating and shielding options. All components are validated for mechanical durability and MSA footprint compatibility.

Whether for spine switches or high-density line cards, our QSFP cages and QSFP connectors deliver the mechanical reliability and EMI protection required for stable 40G deployments.

Frequently Asked Questions about QSFP Cages & Connectors

Q: What is a QSFP cage used for?
A: A QSFP cage mounts and shields QSFP transceivers, helping with alignment, EMI control, and thermal management.

Q: Are QSFP connectors compatible with QSFP+ modules?
A: QSFP and QSFP+ have related footprints; compatibility depends on form factor and MSA specifications—Trxcom can advise per model.

Q: Do you provide multi-port QSFP cage assemblies?
A: Yes, we supply multi-port cages and integrated EMI solutions for high-density applications.
