Huawei OCT Optical Module

Huawei OCT optical modules are high-performance, pluggable devices that convert electrical signals to optical signals, supporting data center and enterprise networks with speeds from GE to 800GE.

Overview

Huawei optical modules are essential components in fiber optic communication systems, performing electrical-to-optical and optical-to-electrical signal conversion for network transmission . They are widely used in data centers, enterprise networks, and AI-driven high-speed networks, ensuring stable, secure, and long-distance connectivity . Huawei provides a full range of pluggable optical modules with flexible plug-and-play options for various interfaces .

Types and Form Factors

Huawei optical modules come in multiple form factors to meet different network requirements :

• SFP (Small Form-factor Pluggable): Supports GE connections with LC fiber connectors.
• eSFP: Enhanced SFP with monitoring for voltage, temperature, bias current, and optical power.
• SFP+: High-speed version of SFP, typically for 10GE.
• SFP28: Supports 25GE with the same interface size as SFP+.
• XFP: 10 Gigabit module, larger than SFP+ with LC connectors.
• QSFP+ (Quad SFP): Supports 40GE with MPO fiber connectors.
• QSFP28: Supports 100GE or 40GE, same interface size as QSFP+.
• CFP (Centum Form-factor Pluggable): Large module for high-speed data communication, dimensions 144.75 mm x 82 mm x 13.6 mm.
• QSFP-DD: Double-density module for higher bandwidth, typically consuming 12–14 watts .
