Datacom and Telecom Connectors
Remke’s RJ45 Ethernet Connectors and Cabling Solutions for Cat 5 and Cat 6A applications enable quick and easy in-field installation without the need for any special tools, which makes them ideally suited for extending data networks, repairing cable links, and incorporating new peripheral devices into existing networks. The field-wireable RJ45 Ethernet connectors are German engineered for extreme performance and quality and feature a zinc die-cast housing with a hardened and tempered finish to prevent outside electrical interference, a long release latch for easy insertion and withdrawal in tight spaces, a standardized plug interface according to the EN 60603-7-51 standard, 360° shielding to ensure secure data transmissions in noisy environments, and integrated strain relief. They also have a four-chamber wire manager with color coding to easily identify T568A, T568B, and PROFINET cables, piercing IDC contacts compatible with 27/7–22/7AWG, 26/1–22/AWG, and 29/19–24/19AWG wire and rugged enough for up for four reuse cycles, and a cap that prevents contacts from dirt and damage during transit and assembly, and are rated for a minimum of 750 mating cycles in operating temperatures extending from -40°C to +85°C. Ideal application areas include office networks, data centers, and industrial automation cabling.
TE Connectivity’s new STRADA Whisper R backplane connectors are designed to make future data center system upgrades easier and more cost effective. They have a newly optimized footprint that helps ensure low crosstalk noise and enables the migration path from 56G PAM4 to 112G PAM4, the same mating interface and excellent electrical performance as the existing STRADA Whisper connectors, with which they’re backwards compatible, and — thanks to the new design and a fully automated assembly process — are more cost-effective than the previous design. The connectors are available in four-pair configurations with 92Ω impedance for traditional backplane applications but can support both 85Ω and 100Ω impedance system requirements. Ideal applications for the series include data centers, servers, storage devices, and wireless infrastructure. Datacom and Telecom Connectors

Rosenberger’s Identification Patch Cord (IDP) makes it quicker and easier to accurately identify patch cord ends in data center, information technology (IT), and building cabling applications, which frequently require the reconfiguration of data cables and generally enact that process by manually patching cables within distributors. Designed to prevent the disruption of active data transmissions caused by unplugging the wrong patch cord, which often happens even if technicians proactively consult and double-check the cabling documentation, the IDP features an external light source that can be placed at the connector on one end of a patch cord to securely identify the other end. The IDP solution also eliminates the need for active electrical or optical components, which enables easier and most cost-effective retrofits of existing fiber optic cabling in data centers, and is kink and crush resistant, rated for operating temperatures extending from -10°C to +60°C, and compatible with cable lengths up to 35m.
