Optical modules used in Huawei 5268 equipment

Huawei 5268 equipment supports a variety of optical modules including SFP, SFP+, SFP28, QSFP+, QSFP28, and BIDI modules for flexible network connectivity.

Supported Optical Module Types

Huawei 5268 devices are compatible with multiple pluggable optical transceivers, which differ in form factor, transmission rate, and connector type:

• SFP (Small Form-Factor Pluggable): Supports Gigabit Ethernet (GE) and Fast Ethernet (FE) with LC fiber connectors. Ideal for standard 1 Gbit/s links .
• SFP+ (Small Form-Factor Pluggable Plus): Enhanced SFP supporting 10 Gbit/s transmission, also using LC connectors .
• SFP28: Same interface size as SFP+, designed for 25 Gbit/s links, suitable for high-speed data center connections .
• QSFP+ (Quad Small Form-Factor Pluggable): Supports 40 Gbit/s transmission, uses MPO fiber connectors, and is larger than SFP+ modules .
• QSFP28: Compatible with 100 Gbit/s or 40 Gbit/s transmission, same interface size as QSFP+ .
• BIDI (Bidirectional) Optical Modules: Uses WDM technology to transmit and receive signals over a single fiber, reducing cabling requirements. Requires paired modules with matched wavelengths .

Key Features

• Hot-swappable: All modules can be replaced without powering down the device .
• Monitoring capabilities: eSFP modules provide real-time monitoring of voltage, temperature, bias current, and optical power .
• Flexible deployment: Modules support short-distance, long-distance, and data center applications, allowing plug-and-play installation .
• Connector types: LC connectors for SFP/SFP+/SFP28/XFP, MPO connectors for QSFP/QSFP28 .

Practical Considerations

When selecting an optical module for Huawei 5268:

• Match the transmission rate (1G, 10G, 25G, 40G, 100G) with the network requirement .
• Ensure fiber type compatibility (single-mode or multi-mode) and connector type.
• For BIDI modules, pair modules with complementary wavelengths to enable bidirectional communication over a single fiber .
• Check power consumption and device specifications, especially for high-density QSFP-DD modules in data centers . Huawei 5268's support for a wide range of optical modules provides flexibility for network expansion, high-speed data transmission, and efficient fiber management.
