100G Transceiver
Our 100G Transceiver lineup includes several QSFP28 models: SR4 (100m multimode), CWDM4 (2km), LR4 (10km), ER4 (40km), and single‑lane DR1/FR1/LR1. Each serves a different reach or fiber type. This article focuses on the 100G QSFP28 LR4 – the industry standard for 10km links. For other models, please browse our website or contact our sales team (sales@macrochip.com.cn).
Key Specifications & Features
- Data Rate & Reach
Supports 103.1Gb/s aggregate. Maximum link length: 10km over standard 9/125μm single‑mode fiber (SMF). Duplex LC receptacle keeps cabling simple.
- Optical Design
Uses 4x DFB‑based LAN‑WDM lasers with central wavelengths at 1295.56, 1300.05, 1304.58 and 1309.14 nm. The four optical signals are multiplexed onto a single fiber pair – no external mux/demux needed. Compliant with IEEE 802.3ba 100GBASE‑LR4.
- Electrical Interface
High‑speed side follows 802.3bm CAUI‑4 (4x25Gb/s). Low‑speed management complies with SFF‑8679.
- Power & Management
Power dissipation <4W from a single 3.3V supply. Digital diagnostic functions available via I2C (SFF‑8636) – monitor temperature, voltage, laser bias, and optical power in real time.
- Environment & Compliance
Case temperature range: 0°C to 70°C. RoHS compliant.
Why Choose This 100G Transceiver?
The LR4 has been the backbone of 10km 100G connectivity for years. It balances reach, power, and cost – ideal for campus backbones, data center interconnects, and metro aggregation. Its mature LAN‑WDM technology ensures broad interoperability with switches from all major vendors.
When you select a 100G Transceiver from our portfolio, you get a reliable, standards‑compliant module ready for immediate deployment. Need shorter reach (e.g., SR4) or longer (ER4)? Explore our other 100G Transceiver options or reach out to our team for a tailored recommendation.

Q: Do you offer custom labels or asset tags on the modules?
A: Yes. We can print your company logo, port numbers, or asset management barcodes on the module label. This is especially helpful for large data centre deployments where tracking hundreds of modules is necessary. Minimum order quantities may apply.
Your trust is the wind beneath our wings.
We never stop improving, because you never stop believing in us.
