QSFP28 ER4 100G
Connecting sites that are tens of kilometers apart without amplification has traditionally been a challenge. The QSFP28 ER4 100G transceiver changes that – it delivers a full 100G link over standard single‑mode fiber for distances up to 40km, making it a practical choice for metro rings, campus backbones, and data center interconnects where LR4 (10km) simply isn't enough.
Why QSFP28 ER4 100G?
When your link spans 30‑40km, you have two choices: add expensive amplification equipment, or use a module with enough optical budget to cover the distance directly. The MCQ-4NSCLC-40 takes the second path. Its APD receiver provides margin for aging fiber plants and multiple patch panels, making it a reliable choice for demanding installations.
For shorter distances (10km or less), our LR4 modules are more cost‑effective. But when you truly need 40km, the QSFP28 ER4 100G delivers without compromise. Need to go further? Ask about our ZR4 solutions for 80km+ links.
FAQ
Q1: What is the warranty and RMA process?
A1: Standard warranty covers manufacturing defects. If a module fails, request an RMA, return the defective unit, and we ship a replacement. For customers in key regions, we keep local spare stock to minimise downtime. Extended warranty and advance replacement options are available.
Q2: Do you offer industrial‑temperature versions for outdoor use?
A2: The standard version is 0°C to 70°C. For outdoor cabinets or harsh environments, we offer custom industrial‑grade modules upon request. Contact our sales team with your specific requirements.
Q3: Does the module support digital diagnostics? What can I see?
A3: Yes, fully compliant with SFF‑8636. Through your switch, you can monitor temperature, voltage, laser bias, and receive optical power per wavelength. This is especially useful for long links – a gradual drop in receive power can indicate a dirty connector or degrading fiber.
