Optical Module 100G
Our optical module 100G family covers eight distinct QSFP28 solutions: SR4, PSM4, CWDM4, LR4, ER4/ER4 lite, DR1, FR1, and LR1. This article focuses on the 100G QSFP28 CWDM4 – the industry's most widely deployed 2km single‑mode module. For information on the other seven models, please browse our website or contact our sales team.
The 100G QSFP28 CWDM4 is designed for 100G Ethernet links over duplex single‑mode fiber with a reach of 2km. It complies with IEEE 802.3bm, QSFP28 MSA, and the CWDM4 MSA (often referred to as the CWDM4 optical specification). On both the electrical and optical sides, it uses four lanes running at 25.78Gbps NRZ per lane – a mature, low‑latency architecture.
Inside the module, four CWDM wavelengths are multiplexed onto a single pair of LC connectors. This allows you to use standard duplex single‑mode cabling instead of parallel MPO‑12 fiber, which is a major advantage for upgrading from 10G or 40G infrastructure. The receiver side uses a PIN photodiode array to demultiplex the four wavelengths.
Power consumption is kept under 3.5W maximum from a 3.3V supply, with an operating case temperature range of 0°C to 70°C. The integrated I²C interface provides full digital diagnostic monitoring (DDM), giving you real‑time access to temperature, voltage, laser bias per lane, and received optical power per lane. The module is RoHS compliant.
Typical applications include 100G Ethernet, 100G CWDM4 links, and data center enterprise networking. For network operators who need a 2km reach without changing their duplex LC cabling, the optical module 100G in its CWDM4 variant is the proven, high‑volume choice. If your reach requirements differ – from 100m (SR4) to 40km (ER4) – explore the rest of the optical module 100G portfolio on our site.
FAQ
Q1: How should I store unused modules?
A1: Store in the original anti‑static bag, inside a closed box away from moisture, direct sunlight, and temperature extremes (ideal 0‑40°C). Always insert the LC dust cap. Do not stack heavy items on top. Static discharge or dust on the ferrule can permanently damage the module.
Q2: Can it be used in industrial environments?
A2: The standard model operates in the commercial temperature range (0°C to 70°C). If you require operation in wider or extreme temperatures, please contact us to inquire about industrial-grade versions.
Q3: Do I need any special tools or knowledge to install it?
A3: The installation is plug-and-play. You simply insert the module into your switch's slot and connect the LC fiber cables. However, it is crucial to ensure the fiber connectors are clean and dust-free. Using a professional fiber optic cleaning pen or lint-free wipes before connection is strongly recommended to prevent signal loss or damage.
our facility
At our facility, we believe quality is integral to every connection we enable. Our comprehensive quality control process begins with stringent inspection of incoming materials and components. Each production stage incorporates in-line testing and verification to ensure precision assembly. Finally, every finished transceiver undergoes a full suite of functional, performance, and reliability tests under various conditions to meet or exceed industry specifications.
