## Summary description

SFP optical module MaxLink ML-S85D-05 provides 1.25 Gbps data rate using an 850 nm wavelength for short-range multimode fiber links up to 550 m. Designed for compact SFP ports, it supports hot-plug installation and is suitable for switches, routers and media converters in local networks and data centers, offering interoperable fiber connectivity for network extension and redundancy.

## Long description

The SFP optical module MaxLink ML-S85D-05 provides 1.25 Gbps data transmission over multimode fiber using an 850 nm wavelength, supporting link distances up to 550 meters. Designed for standard small form-factor pluggable (SFP) ports, this compact transceiver enables hot-pluggable installation and interoperable fiber connectivity for switches, routers and media converters in local networks and data center environments.
Advantages
This SFP transceiver supports a 1.25 Gbps data rate and an 850 nm optical wavelength optimized for short-range multimode fiber links. Its compact SFP form factor allows tool-free insertion and removal while the hot-pluggable design minimizes network downtime during upgrades or maintenance. The module is suitable for typical enterprise and data center hardware that accepts standard SFP transceivers, providing a cost-effective option for extending fiber runs or adding redundant links.
Suitable for
 Short-range multimode fiber links in enterprise LANs
 Interconnects between switches, routers and media converters
 Access and edge network segments in data centers
 Redundant fiber links and network extension projects
Key specifications
 Data rate: 1.25 Gbps (nominal)
 Wavelength: 850 nm (multimode operation)
 Maximum reach: up to 550 meters over multimode fiber (depending on fiber type and link conditions)
 Form factor: SFP (small form-factor pluggable)
 Connector type: standard duplex LC-compatible interface
 Hot-pluggable: supports live insertion and removal
How to use
Insert the SFP module into a compatible SFP port until it seats and latches securely. Connect multimode fiber with appropriate LC duplex patch cords, ensuring correct transmit/receive alignment. Verify link status on the host device and confirm the negotiated speed is 1.25 Gbps. For hot-plug operations, follow the host equipment vendor guidelines to avoid transient traffic disruption. When removing the module, power down affected interfaces if recommended by the equipment manufacturer and release the module latch before extraction.
Usage recommendations
Use high-quality multimode fiber (OM2/OM3/OM4 as appropriate) and maintain proper fiber cleanliness to achieve the specified reach. Check compatibility lists for your switches, routers or media converters to ensure full interoperability. Avoid excessive bending of fiber cables and observe electrostatic discharge precautions when handling the module.
