Carritech works with network operators, service providers, and resellers to secure Coriant hardware that can be difficult to obtain through traditional channels—particularly where platforms are discontinued, lead times are extended, or new supply is no longer viable.
From optical modules and line cards to full systems and essential spare parts, we deliver fully tested equipment with clear provenance and dependable aftersales support. Whether you require a single urgent replacement or a structured supply strategy for ongoing maintenance, we help ensure continuity, budget control, and network resilience.
Carritech helps organisations realise value from excess, idle, or end-of-life Coriant assets. We purchase a broad range of equipment—including optical transceivers, line cards, shelves, and system spares—providing a secure and efficient route to market.
By converting unused inventory into immediate revenue, we help reduce storage overheads while supporting sustainable reuse within the telecoms supply chain. If you’re looking to release capital tied up in Coriant stock and simplify your asset footprint, we’re ready to help.
Carritech provides specialist repair services for Coriant network hardware, supporting both legacy platforms and live operational networks. Our repair capability helps minimise disruption while avoiding the cost and delay associated with sourcing replacement units.
We offer component-level repairs across a wide range of equipment, including optical modules, line cards, control boards, and system components. Every repair is fully tested and quality-assured, delivering a reliable, cost-effective alternative to new hardware and helping keep critical infrastructure in service for longer.
Carritech delivers L3 remote technical support for Coriant platforms, helping operators and service providers maintain stable, high-performing networks long after OEM support has ended.
Our engineers assist with fault isolation, configuration challenges, software issues, and ongoing operational support across live and legacy environments. By extending platform viability and filling skills gaps, we help reduce operational risk, control support costs, and maintain network continuity where in-house resources are stretched.
Coriant was incorporated as an independent company in 2013 as a spin-out from Siemens Optical Networks (NSN ON). The launch of the company was announced for the OFC/NFOEC in March 2013 and on May 6, 2013 Coriant became independent from Nokia Siemens Networks under the ownership of Marlin Equity Partners.
Coriant merged with Sycamore Networks (acquired by Marlin Equity in January 2013 and headquartered in Chelmsford, Massachusetts), which continued operating as Coriant America Inc.
Marlin Equity merged Coriant and Tellabs (acquired by Marlin Equity in December 2013 Naperville, Illinois), which continued as Coriant. Later, the telco and GPON related components of the company were spun back out as a new company, also called Tellabs.
Coriant was acquired by Infinera in 2018.
