Fujitsu HM2H-BLSR FLM-2400 Blsr HS Multiplexer

Overview
The Fujitsu HM2H-BLSR, marketed as the FLM-2400 BLSR HS Multiplexer, is a high-performance optical transport solution designed for dense wavelength division multiplexing (DWDM) networks. Engineered for carrier-grade reliability, this multiplexer consolidates multiple optical signals onto a single fiber, maximizing bandwidth while minimizing infrastructure costs. Its compact form factor and low power consumption make it ideal for both metro and long-haul deployments.

Key Features

• Supports up to 40 channels of 100 Gbps each with a total capacity of 4 Tbps
• Hybrid lattice and slab waveguide design for low insertion loss and high channel isolation
• Automatic channel power balancing to maintain optimal signal quality
• Built-in optical performance monitoring (OPM) for real-time OSNR and wavelength tracking
• Redundant power supplies and hot-swap modules for uninterrupted service
• Compact 2U rack mount chassis with front-panel status LEDs

Technical Specifications

• Wavelength range: 1525 nm to 1565 nm (C band)
• Channel spacing: 50 GHz (0.4 nm) or 100 GHz (0.8 nm) selectable
• Insertion loss: < 1.5 dB typical
• Polarization mode dispersion: < 0.1 ps/sqrt(km)
• Operating temperature: 0 to 45 degrees Celsius
• Power consumption: 150 W max (with dual redundant supplies)
• Management interface: SNMP v2c/v3, web GUI, CLI over Ethernet

Applications
The FLM-2400 BLSR HS Multiplexer is suited for a wide range of telecom and data transport scenarios, including:

• Metro ring and mesh networks requiring high density channel aggregation
• Backbone links between data centers where low latency and high capacity are critical
• Carrier Ethernet services such as 100 Gbps Ethernet over DWDM
• Enterprise campus extensions that need scalable bandwidth without laying new fiber
• Network upgrade paths where existing infrastructure can be leveraged with minimal disruption

By integrating the Fujitsu HM2H-BLSR into your optical network, you gain a reliable, scalable, and energy-efficient solution that simplifies network design while delivering the performance demanded by modern high-speed applications.
