SFP+ optical module MaxLink ML-S+3327-20 WDM Tx 1330nm Rx 1270nm 10G

The MaxLink ML-S+3327-20 is a 10G SFP+ optical module designed for single-fiber WDM links. It transmits at 1330 nm and receives at 1270 nm, enabling duplex 10 Gigabit Ethernet connectivity over one optical fiber using wavelength division multiplexing. The module is intended for use in network equipment with SFP+ ports and is compatible with applications that require long-reach, cost-effective single-fiber links between switches, routers and media converters.

Advantages

This SFP+ transceiver supports 10 Gigabit Ethernet speeds while using a single fiber pair for bidirectional traffic, reducing fiber infrastructure requirements. The WDM Tx 1330nm / Rx 1270nm configuration provides clear wavelength separation for reliable duplex transmission. The compact SFP+ form factor allows direct insertion into compatible switch, router or media converter ports, offering straightforward deployment without additional modules or adapters. The module is suitable for standard SFP+ power and signal interfaces used in modern networking equipment.

Suitable for

• 10 Gigabit Ethernet connections over single-fiber links
• Interconnecting switches and routers in campus and metro networks
• Media converter deployments requiring SFP+ single-fiber WDM transceivers
• Upgrading existing fiber runs to support duplex traffic without adding fibers

Key specifications

• Interface: SFP+ form factor for 10G links
• Tx wavelength: 1330 nm
• Rx wavelength: 1270 nm
• Data rate: 10 Gigabit Ethernet
• Transmission mode: Wavelength division multiplexing (single-fiber duplex)

How to use

Insert the MaxLink ML-S+3327-20 into an available SFP+ port of a compatible switch, router or media converter. Connect the single-mode fiber cable ensuring correct polarity and fiber connector type. Verify that the linked device is configured for 10G operation and supports SFP+ transceivers. After insertion and fiber connection, check link LEDs or management interfaces to confirm the optical link is established and operating at the expected rate.

Usage recommendations

Ensure that connected equipment supports SFP+ modules and the WDM wavelengths used (Tx 1330 nm / Rx 1270 nm). Use single-mode fiber and appropriate connectors for long-reach deployments. Observe manufacturer guidelines for electrostatic discharge (ESD) protection during installation and avoid bending the fiber beyond its minimum bend radius to maintain signal quality.
