Can this 1330nm CWDM module operate over standard OS2 single-mode fiber for the full 20 km distance, and does it support DOM monitoring?

Yes. The LS-CW3310-20C is designed for 10 Gigabit Ethernet transmission over standard OS2 single-mode fiber with a maximum reach of 20 km. It uses a Duplex LC optical interface and supports Digital Optical Monitoring (DOM/DDM), allowing real-time monitoring of transmit power, receive power, module temperature, supply voltage, and laser bias current. It is widely used in campus backbones, metro Ethernet, enterprise networks, and carrier access deployments.

Has anyone tested the LS-CW3310-20C with Cisco, Juniper, HPE, Huawei, or MikroTik switches? Does it require any special configuration?

The LS-CW3310-20C complies with the SFP+ MSA standard and supports OEM-compatible coding. It has been successfully deployed with Cisco, Juniper, HPE, Huawei, H3C, MikroTik, Dell, and many other compatible 10G platforms. In most cases, the module is recognized automatically without additional configuration. If you have a specific switch model, our technical team can verify compatibility before shipment.

We're planning to purchase more than 200 units for a campus network project. Do you offer bulk discounts or OEM customization?

Yes. LINK-PP provides project-based pricing for volume orders and supports OEM/ODM services, including customized EEPROM coding, private labeling, logo printing, customized packaging, and part number customization. Send us your required quantity and equipment list, and we'll prepare a competitive quotation.

We've tested these modules with Cisco, Juniper, HPE, and Huawei switches. Every transceiver was recognized correctly, and all 10GbE links established without compatibility issues. The Duplex LC connector matched our existing fiber infrastructure perfectly.

Installed this 10G SFP+ 1330nm CWDM transceiver on a 20 km OS2 single-mode fiber link between two office buildings. The 10 Gigabit Ethernet connection came online immediately, and DOM monitoring has remained accurate during continuous operation.
