Alcatel/Nokia 3HE06151AA A8-1GB-SFP

The Alcatel/Nokia 3HE06151AA A8-1GB-SFP is a specific type of networking module. 

  Overview  

This product is an 8-port Gigabit Ethernet Service Interface Module designed for use in larger Alcatel-Lucent (now Nokia) carrier-grade routers and switches, such as the 7750 Service Router (SR) and 7450 Ethernet Service Switch (ESS) families.

• Manufacturer: Originally Alcatel-Lucent, now part of Nokia.
• Part Number: 3HE06151AA
• Model Name: A8-1GB-SFP
• A8: Indicates an "Adapter" module with 8 ports.
• 1GB: Indicates each port is a 1 Gigabit Ethernet port.
• SFP: Indicates the physical interface type. The ports are SFP cages (slots), which require separate SFP transceivers (optical or copper) to actually connect to a fiber or network cable.

  Key Features and Functionality  

Purpose: It is a service module or interface card. Its primary job is to provide network connectivity for delivering advanced carrier Ethernet services like:

• E-Line (Point-to-Point Ethernet Virtual Leased Lines)
• E-LAN (Multipoint-to-Multipoint Ethernet LAN Service)
• Business Internet Access
• Mobile Backhaul (3G, 4G/LTE, 5G)

Ports: 8 x Gigabit Ethernet ports. Each port is an SFP cage, offering flexibility.

Flexibility via SFPs: The use of SFP cages is a critical feature. It allows a network operator to choose the appropriate SFP transceiver for each port based on the required distance and cable type, for example:

SFP, SFP+: 1G/10G Transceivers

1000BASE-T SFP: For copper/RJ-45 connections up to 100 meters.

1000BASE-SX SFP: For multi-mode fiber (short reach).

1000BASE-LX/LH SFP: For single-mode fiber (long reach).

Advanced Services: This module supports Nokia's full suite of advanced IP/MPLS features, including:

Quality of Service (QoS) for traffic prioritization.

VLAN tagging (802.1Q).

Security and ACLs (Access Control Lists).

Detailed statistics and monitoring.

  Typical Use Cases  

This module is found in the core of service provider networks (telecom companies, ISPs) and large enterprise networks, specifically:

Internet Service Providers (ISPs): To connect business customers to the internet or to provide point-to-point private lines between offices.

Mobile Network Operators: In cell site aggregation routers to backhaul traffic from many cell towers to the core network.

Data Centers: For network interconnection and providing services to tenants.

  Compatibility 

This card is designed to be installed into a slot on a Nokia chassis, such as:

Nokia 7750 SR series (e.g., 7750 SR-1, SR-7, SR-12, SR-14)

Nokia 7450 ESS series

Nokia 7950 XRS series (though newer platforms may use more advanced modules)

In short, the Nokia 3HE06151AA A8-1GB-SFP is not a standalone device but a critical component that slots into a high-end Nokia router. It provides eight flexible Gigabit Ethernet ports that carriers use to deliver reliable and feature-rich Ethernet services to their customers. Its value lies in its flexibility (thanks to SFP slots) and its support for carrier-class features and reliability.
