In a multi-dwelling FTTH rollout, network operators deploy the WS-X4424-GB-RJ45 Base-X FE linecard in a Catalyst 4500-E switch chassis and populate all 48 SFP slots with GLC-FE-100BX-D48 modules. This architecture delivers 100 Mbps Ethernet to each subscriber over single-mode fiber, centralizes service provisioning, scales to thousands of ports per shelf, and reduces operational costs by up to 30% through simplified fiber aggregation and automated provisioning.
A global enterprise integrates WS-X4424-GB-RJ45 Base-X FE linecards in its core Catalyst switches and uses GLC-FE-100BX-D48 SFP FTTH modules at seven building distribution closets. Each module provides secure fiber uplinks to IP phones, workstations, and Wi-Fi APs across 2 km spans. The result is consistent Fast Ethernet performance, enhanced physical security, streamlined cable management, and centralized QoS enforcement for voice and data traffic.
A regional bank implements a dual-chassis ring using two Catalyst 4500-E switches equipped with WS-X4424-GB-RJ45 Base-X FE linecards and GLC-FE-100BX-D48 FTTH modules over dark fiber. The Fast Ethernet ring runs sub-50 ms protection switching, ensuring uninterrupted connectivity for ATM networks, core transaction servers, and VPN gateways. This design maximizes network uptime, simplifies failover configurations, and supports regulatory compliance for high-availability financial services.

The WS-X4424-GB-RJ45 offers exceptional value. It delivers fast, reliable connections and integrates smoothly into our network infrastructure.
The WS-X4424-GB-RJ45 is a 48-port 100 Mbps SFP access module designed for FTTH deployments. It delivers high-density fiber connectivity and requires the GLC-FE-100BX-D48 Base-X FE line card.
This module provides 48 independent 100 Mbps SFP ports, each supporting hot-swappable FE SFP transceivers for flexible fiber connectivity.
The WS-X4424-GB-RJ45 requires the Cisco GLC-FE-100BX-D48 Base-X FE line card to operate. No other line card is supported.
Use Cisco-certified 100BASE-FX single-mode SFPs such as GLC-FE-100BX-D to ensure full compatibility and optimal performance.
This module supports single-mode fiber (SMF) with LC connectors. Use standard 9/125 µm SMF cables for optimal signal integrity.
With a GLC-FE-100BX-D transceiver, you can reach up to 120 km on single-mode fiber under standard conditions.
The WS-X4424-GB-RJ45 is compatible with Cisco Catalyst 4500 and 4400 E-Series chassis that accept Base-X FE line cards.
Power down the chassis, slide the module into an available slot, secure the captive screws, install the GLC-FE-100BX-D48 line card, and power up. The system auto-detects the module.
Enter global configuration: interface range gigabitEthernet 1/1–1/48, set speed 100, duplex full, and no shutdown. Verify with show interfaces status.
Issue show module and show interface transceiver details. Look for port status 'connected' and optical parameters within Cisco-specified thresholds.
Supports SFP Digital Optical Monitoring (DOM) for real-time metrics on optical power, temperature, voltage and laser bias current via SNMP or CLI.
Typical power draw is 20 W for the fully populated 48-port module, depending on transceiver type and cable length.
The module operates reliably between 0 °C and 40 °C (32 °F to 104 °F) with storage range from –40 °C to 85 °C.
