The Alcatel 7353 ISAM CX (Compact Flexible modular Optical Network Unit) is a hardened, space-efficient broadband access device designed for Fiber-to-the-Building (FTTB) and multi-dwelling unit (MDU) environments. With a slim 1U form factor (44 mm high, 442 mm wide, 245 mm deep), it is well-suited for both wall-mounted and rack-mounted installations, offering configurations with either 16 or 24 VDSL2 ports.
Despite its compact design, the platform supports a variety of access technologies including VDSL2, ADSL2+, and POTS overlay via integrated splitters. It offers uplink flexibility through Gigabit Ethernet, GPON, or point-to-point fiber interfaces, enabling operators to match infrastructure capabilities to local service demands.
The unit operates without internal fans, making it ideal for quiet deployment environments such as residential buildings or office basements. It supports multiple power input types, including AC, DC, and optional battery backup, and is suitable for both indoor and sheltered outdoor locations thanks to its ruggedized build.
The ISAM CX platform is optimized for small-scale deployments that require high reliability and minimal maintenance. With a non-modular chassis design, it simplifies installation and reduces operational complexity while supporting advanced broadband services such as IPTV, VoIP, and high-speed data.
Carritech offers full lifecycle support for the Alcatel 7353 ISAM CX, including spare parts, hardware refurbishment, repair services, and technical consultation—helping network operators extend the life and performance of their infrastructure.

The Alcatel 7353 ISAM CX is a compact, hardened Optical Network Unit (ONU) designed for Fiber‑to‑the‑Building (FTTB) and multi-dwelling unit (MDU) broadband deployments. The device features a slim 1‑rack‑unit chassis (44 mm high × 442 mm wide × 245 mm deep) with available configurations supporting 16 or 24 VDSL2 subscriber ports. Optional modules allow support for ADSL2+ and POTS overlay via splitters, enabling voice and data convergence within a single compact node.
The unit’s fanless, convection-cooled design provides silent operation and increased reliability, with no moving parts and lower risk of mechanical failure. It supports multiple power input types—AC, -48 V DC, or battery backup—and is housed in rugged enclosures suitable for indoor or sheltered outdoor installations. Mounting options include wall-attachment or standard 19-inch rack integration.
Access services are delivered over copper using VDSL2—with vectoring and pair-bonding support where line conditions permit—auggmented by legacy ADSL2+ and SHDSL where needed. Uplinks to aggregation or transport networks are provided via Gigabit Ethernet, GPON, or point-to-point fiber modules, enabling flexible deployment architectures.
The platform supports IP-based triple-play services, including IPTV, VoIP, and high-speed data. Built-in packet management features include VLAN tagging, per-user Quality of Service (QoS) enforcement, multicast replication, and subscriber authentication. The slim form factor and high functionality make it ideal for delivering robust services in tight telecom spaces while maintaining performance parity with larger network nodes.
System reliability is enhanced through support for redundant power, while hot-swappable modules and in-service provisioning facilitate maintenance and expansion without interrupting customer services. Management and provisioning capabilities are available through standard interfaces like CLI and SNMP, and integrate with centralized network management systems. Diagnostic tools and alarm reporting aid effective fault isolation and proactive maintenance.
Designed to meet carrier-grade environmental standards (compliant with ETSI and meeting NEBS Class 3 criteria), the 7353 ISAM CX offers a dependable, scalable access node solution where space, quiet operation, and flexibility are paramount.
