ALCATEL LUCENT 3EA73007ACJE Circuit Card

ALCATEL LUCENT 3EA73007ACJE Circuit Card

Product Details Introduction

The 3EA73007ACJE Circuit Card from Alcatel Lucent (now part of Nokia) is a critical hardware component in its communication equipment, typically used for signal processing, interface expansion, or system control in high-performance network devices. The following are typical application areas and functional analysis:

1. Core application areas

(1) Optical Transmission Network (OTN/DWDM)

May be used for 1830 Photonic Service Switch (PSS) series optical transmission equipment, undertaking the following functions:

Optical signal multiplexing/demultiplexing (such as DWDM wavelength management).

Cross connection of electrical layers (such as OTN switching).

Performance monitoring (such as optical power and bit error rate detection).

(2) IP/MPLS backbone network equipment

Integrated into high-end routers such as 7750 SR/7450 ESS, it may serve as:

High speed interface card (such as 100G/400G Ethernet or OTN interface).

Control plane coprocessor to assist the main control board in completing routing calculations or traffic engineering.

(3) Mobile backhaul and edge networks

In 4G/5G Mobile Backhaul devices, it may be used for:

Protocol conversion (such as adaptation from IP to optical layer).

Time synchronization (supported by 1588v2 precise time protocol).

2. Specific functional speculation

Interface type: May support high-speed optical modules (such as SFP+/QSFP28) or electrical interfaces (such as 10G/40G/100G Ethernet).

Signal processing: may include FPGA or ASIC chips for packet processing, traffic shaping, or forward error correction (FEC).

Redundant design: Supports hot swapping and meets carrier grade high reliability (such as 99.999% availability).

3. Typical industry applications

Telecom operator: used for backbone network expansion or data center interconnection (DCI).

Cloud service provider: supporting high-speed connections between ultra large scale data centers.

Key infrastructure: dedicated communication networks for industries such as energy and transportation.
