About This Part
The Alcatel-Lucent STM1-2M IR (SKU 90-4909-16/A) is a crucial interface module designed for Synchronous Digital Hierarchy (SDH) networks. This card facilitates the aggregation and transport of multiple 2 Mbps (E1) or 1.5 Mbps (T1) tributary signals over a high-capacity STM-1 optical link, which operates at 155.52 Mbps. The "IR" designation signifies its suitability for Intermediate Reach optical applications, typically supporting distances up to 15-40 km, depending on specific fiber characteristics and system configuration. It serves as an essential component for bridging legacy E1/T1 infrastructure with modern optical transport networks. In telecom and data centre environments, the STM1-2M IR module is commonly deployed in access and metro networks. Its primary use case involves enabling service providers to consolidate numerous lower-speed voice and data circuits from customer premises equipment or older network elements onto a single, efficient optical stream. This capability is vital for the cost-effective backhaul of services such as traditional telephony (PSTN), leased lines, and early-generation data services, ensuring seamless interoperability and optimal utilization of network resources, particularly where E1/T1 services remain prevalent. Revo Distribution Limited proudly offers the Alcatel-Lucent STM1-2M IR (90-4909-16/A) as part of our extensive inventory of used and refurbished telecom equipment. By providing rigorously tested and refurbished units of this proven component, Revo supports network operators in maintaining and expanding their existing SDH infrastructure without the prohibitive costs associated with new hardware.
