Which connector should I use for the H3C optical module

Optical access and telecom site reference Published 09 Jan 2025

Use this reference to prepare product questions for CGWEB NETWORKS. Check interfaces, capacity, protection and installation requirements against the current product documentation.

H3C optical transceiver modules use LC, SC, or MPO connectors depending on the module type and application. Connector Types by ModuleLC (Lucent Connector): Commonly used for SFP and QSFP-100G-LR4 modules, especially for single-mode fiber connections up to 10 km.

Duplex L

C connectors are standard for modules like the H3C QSFP-100G-LR4-WDM1300.

S

C (Subscriber Connector): Supported on some H3C modules, typically for legacy or specific fiber applications.

MP

O (Multi-fiber Push On): Used for high-density, multi-fiber modules such as QSFP-100G-SR4 or other 100G SR modules.

H3

C modules use female MPO connectors with guide holes, available in 12, 16, or 24 fibers, and with either PC (Physical Contact) or APC (Angle-polished Contact) polish types.

MP

O connectors are often used with breakout cables to connect to multiple LC duplex fibers. Practical GuidanceSingle-mode fiber (SMF): Use duplex LC connectors for long-distance links (e.g., 10 km for 100G LR4 modules),. Multi-mode fiber (MMF): Use MPO/MTP connectors for short-distance, high-bandwidth links (e.g., 100G SR4 modules up to 100 m on OM4 fiber),.

Hybrid or Po

E ports: Some H3C APs require LC connectors with SFP modules or hybrid copper-fiber cables for photoelectric hybrid ports.

Installation Tips

Always cover unused connectors with dust caps to prevent contamination. Align the fiber connector carefully with the transceiver optical bore; H3C modules have disorientation rejection designs to prevent incorrect insertion.

For MP

O modules, ensure the correct polish type (PC or APC) and fiber count match the network design. By selecting the correct connector type based on the module and fiber type, you ensure optimal signal quality and network reliability for H3C optical transceivers.
