QSFP-100G-BIDI-G2 100G QSFP28 BiDi Transceiver Module 70m-100m

The Huawei QSFP-100G-BIDI-G2 is a cutting-edge, hot-pluggable QSFP28 bi-directional (BiDi) optical transceiver designed for high-density 100 Gigabit Ethernet applications. As enterprise networks and hyperscale data centers migrate from legacy 10G and 40G infrastructures to 100G architectures, optimizing existing fiber plants becomes a primary cost-saving strategy.

By utilizing BiDi (Bi-Directional) technology, this module allows the simultaneous transmission and reception of data over a single strain of duplex LC multimode fiber (MMF). It operates on dual wavelengths (850nm and 910nm) over two 50Gbps channels via PAM4 modulation. This breakthrough engineering allows network operators to fully reuse their existing 10G/40G OM3 or OM4 duplex LC cabling infrastructure, eliminating the massive expenses of laying new multi-fiber MPO patch panels and trunk cables.

Review the complete optical, electrical, and environmental parameters below to ensure precise deployment within your hardware ecosystem:

A: The primary difference lies in the fiber cabling infrastructure required and migration costs.

• Standard 100G SR4 Modules: Operate over 8-fiber or 12-fiber MPO/MTP multimode cables, dividing the traffic across 4 separate parallel lanes (4x25G).

• Huawei QSFP-100G-BIDI-G2 Modules: Consolidate the traffic into two 50G lanes using dual wavelengths (850nm/910nm) over a standard 2-fiber duplex LC cable.

  If your data center currently utilizes standard LC patch cords from old 10G or 40G BiDi switches, deploying the G2 BiDi module saves you from purchasing expensive MPO trunk cables and rewriting your fiber patch cords.

A: This specific module is natively coded to support Huawei enterprise switches, routers, and firewalls. However, LonRise specializes in custom EEPROM hardware coding. If your data center environment requires multi-vendor interoperability (for example, connecting a Huawei core backbone router to a Cisco Catalyst 9300L switch), please specify your target equipment when sending an inquiry. We can supply fully compatible or cross-coded variants to ensure seamless plug-and-play operation.

A: The QSFP-100G-BIDI-G2 utilizes advanced optical PAM4 (4-level Pulse Amplitude Modulation) technology to transmit 50Gbps per optical lane. Because PAM4 signaling is highly complex and more sensitive to optical noise than older NRZ technology, the host switch system must have KP4 FEC enabled to correct bit errors automatically, guaranteeing a stable, error-free link across the 70m/100m range.

A: LonRise provides a comprehensive enterprise-grade after-sales support system for all our B2B customers:

1. 1-Year Warranty: Every brand-new Huawei module includes a 1-year replacement or repair warranty against manufacturing and materials defects.

2. Rigorous Pre-Shipment Testing: All modules undergo strict compatibility, signal integrity, and optical power inspection in our test labs before dispatching.

3. Remote Technical Assistance: Our network engineers are available to assist you with remote system configuration, DOM/DDM telemetry interpretation, and cross-vendor link debugging.

A: For standard stock orders, our lead time is 2-3 business days. We ship worldwide from China primarily using DHL, FedEx, and UPS express lines, ensuring that critical network components reach your data center within 3 to 5 business days globally. All packages are securely sealed in anti-static ESD packaging to prevent electrostatic damage during transit.
