Product details
LEMO's RMA.2S.302.CLL sets new benchmarks in the Circular Connectors - Adapters industry with its revolutionary contact technology. Designed for hyperscale data centers, this adapter reduces signal path loss by 30% compared to conventional designs while supporting 56G PAM4 signaling.The Standard configuration implements novel air dielectric spacing that reduces dielectric loss tangent. When compared to PTFE-based designs, this achieves 0.2dB lower insertion loss at 28GHz.Supporting Female Sockets and Male Pins interfaces, this adapter enables seamless migration from QSFP to OSFP form factors. The embedded retimer circuitry compensates for up to 20dB of channel loss.With Female Sockets and Male Pins capability, the adapter supports breakout configurations to four SFP28 interfaces. Each output includes independent signal conditioning with programmable equalization.The 302 interface incorporates heat pipe technology that reduces thermal resistance by 40%. Continuous monitoring points allow real-time temperature tracking.Featuring 302 outputs, the adapter supports direct attach copper cables up to 3 meters. Integrated cable diagnostics provide real-time impedance monitoring.The 2 configuration was optimized for 112G SerDes applications. Skew matching between lanes is maintained below 0.5ps/mm across the entire adapter.Designed for high-density applications, the 2 output supports crosstalk cancellation technology. Near-end crosstalk (NEXT) is reduced by 15dB compared to conventional designs.The Free Hanging (In-Line) option implements cold plate compatibility for liquid cooling systems. The thermal interface maintains less than 0.05 C/W resistance to cooling surfaces.Utilizing Push-Pull technology, the adapter achieves tool-less hot-swap capability. The sequenced mating ensures ground-first connection during live insertion.Selected for its dielectric constant stability, Brass maintains r within 0.02 from 1-40GHz. The material's moisture absorption rate is less than 0.01% by weight.The Silver housing incorporates ESD-dissipative materials with surface resistance of 10^6-10^9 ohms. Color-coding follows TIA-598-D standards for fiber optic identification.While rated for IP50 - Dust Protected, the adapter focuses on particulate protection with >99.97% efficiency at 0.3 microns. This meets ISO 14644-1 Class 5 cleanroom requirements.The Shielded design uses frequency-selective surface technology that provides 60dB attenuation at 28GHz while being transparent to heat dissipation. Shield effectiveness was verified using GTEM cell testing.
