40Gb/s QSFP+ BIDI 850/908nm Optical Transceiver Module — High Density, Low Power, Bi-Directional

1. 40G QSFP+ BIDI SR Product Overview

The CC-QJJ110L-SD is a high-performance 40Gb/s QSFP+ Bi-Directional (BIDI) optical transceiver module designed for high-speed data center and enterprise networking applications. It supports dual wavelength technology (850nm/908nm) over a single fiber strand, enabling efficient use of fiber infrastructure. This optical module operates on a 3.3V power supply and is housed in a rugged metal casing for enhanced durability.

2. 40G QSFP+ BIDI SR Key Characteristics

• Supports 40Gbps data rate with 4x10G NRZ to 2x20G NRZ conversion
• Hot-pluggable QSFP+ form factor
• Reach up to 70m on OM3 and 100m on OM4 multimode fiber
• Dual-wavelength VCSEL-based Bi-Directional optical interface
• Digital diagnostics monitoring with maskable interrupts
• Low power consumption: max 3.5W
• Operating case temperature: 0°C to 70°C
• RoHS II compliant

3. 40G QSFP+ BIDI SR Technology & Standards

This optical transceiver module complies with QSFP+ MSA standards and uses NRZ modulation. It supports Bi-Directional communication over a single fiber via wavelength division multiplexing (WDM). The device is designed to meet Class 1 laser safety standards per IEC 60825-1 and FDA regulations.

4. 40G QSFP+ BIDI SR Working Principle

The module converts 4x10.3125 Gbps electrical input signals into 2x20.625 Gbps optical signals using two different wavelengths (850nm and 908nm). These are transmitted and received over a single LC fiber interface, allowing full-duplex 40G communication. Integrated DSP ensures signal integrity and monitoring capabilities.
