## Summary description

10G SFP+ optical module MaxLink ML-S+3327-20 supports WDM transmission with Tx wavelength 1330 nm and Rx wavelength 1270 nm. Designed for 10 Gigabit Ethernet links, this transceiver provides duplex over a single fiber using wavelength division multiplexing. Suitable for switches, routers and media converters requiring SFP+ ports and single-fiber long‑reach connections.

## Long description

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)
 Application: Single-fiber long-reach connections between network devices
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.
