Key features

Fully optimized for SONET and SDH optical fiber transmission systems, ensuring stable high-speed clock and data link communication.

Exceptionally low interwinding capacitance of only 6.0 pF max minimizes high-frequency noise coupling and boosts EMI immunity.

Ultra-low leakage inductance of 0.10 uH max guarantees outstanding signal integrity and prevents narrow pulse distortion.

Offers precise primary inductance options (36 uH for CL7301X, 42 uH for CL7302X) tailored for high-frequency signal shaping.

Features a highly precise 1:1 turns ratio (plus or minus 5 percent) for perfectly balanced input and output signal matching.

Built with 1500Vrms isolation voltage to protect downstream high-speed transceivers and logic circuits from line surges.

Super compact 12.80x6.90x6.50 mm miniature SMT package saves valuable board space for high-density telecom line cards.

100% Lead-Free (Pb-Free) and fully RoHS compliant, making it easy for overseas buyers to clear green environmental audits.

Ideal for optical transceivers, core routers, telecom multiplexers, and high-speed digital carrier systems.

Produced under strict original factory conditions with reliable long-term supply capacity guaranteed by CoreLogic infrastructure.

Supplier typeThe supplier is identified as Beijing Corelogic Communication Co., Ltd., a limited company with 32 employees and an associated company. Its business scope covers technology services and the sale or production of communication equipment, electronic products, instruments, electronic components, and related software; its listed primary products are GNSS timing synchronizers, GNSS antennas, alarm extension modules, and splitters.

After-Sales capabilityThe supplier has documented procedures and records for service assessment, corrective and preventive actions, and customer complaint handling, and it reports in-stock capability. However, it has no overseas warehouse, showroom, overseas agents, or branches, and reports service coverage in zero countries, limiting evidence of international after-sales infrastructure.

R&D capabilityThe supplier reports that it had new products during the past year and provides ODM services, indicating product-development activity. It also reports no available SDK, so the evidence supports some innovation capability but does not establish broader software-development or platform capability.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM service availability, providing direct evidence of broad customization support.
