## Summary description

Single-mode SFP fiber transceiver Grandstream GF-SM1310-20KM-1.25G supports 1.25 Gbps data rate and up to 20 km transmission distance. Designed for use in switches, routers and media converters with SFP slots, it enables long-distance optical links over single-mode fiber for network uplinks, CCTV, and ISP connections, providing reliable connectivity.

## Long description

The Grandstream GF-SM1310-20KM-1.25G SFP fiber module is a single-mode optical transceiver designed for 1.25 Gbps data links up to 20 km over single-mode fiber. Intended for insertion into standard SFP ports on switches, routers and media converters, this module provides a compact, hot-swappable solution for creating reliable long-distance optical connections for network uplinks, CCTV systems and ISP access links.
Advantages
This single-mode SFP transceiver supports a 1.25 Gbps data rate and is optimized for long-reach links up to 20 km, reducing the need for intermediate active devices. Its compact SFP form factor enables hot-swap installation and compatibility with a wide range of networking equipment that accepts SFP modules. The module is engineered to offer stable optical performance and low power consumption suitable for continuous operation in rack-mounted and distributed network environments.
Suitable for
Creating fiber uplinks between switches and routers in enterprise and campus networks
Extending video and data links for IP CCTV and security camera systems
Providing last-mile or backhaul connectivity for ISPs and service providers
Integrating with media converters to connect copper and fiber segments
Key specifications
Optical mode: single-mode fiber
Data rate: 1.25 Gbps (SFP nominal rate)
Maximum link distance: up to 20 km over appropriate single-mode fiber
Connector type: LC duplex
Wavelength: 1310 nm transmit (compatible with standard single-mode optics)
Form factor: SFP (small form-factor pluggable), hot-swappable
Power consumption: low-power design suitable for continuous operation
How to use
Power down is not required for installation in most systems that support hot-swappable SFPs. Insert the module into an available SFP slot until it seats firmly, then connect a duplex LC single-mode fiber patch cable observing correct TX/RX orientation. Verify link status using the host device's port indicators or management interface and configure interface speed or auto-negotiation settings as required by the connected devices. For optimal performance, use matched single-mode fiber and verify cleanliness of LC connectors prior to mating.
Usage recommendations
Install and remove the module using ESD precautions, keep LC connectors covered when not in use, and perform connector cleaning with appropriate fiber cleaning tools. Use fiber infrastructure rated for single-mode transmission and ensure transceiver wavelength and fiber type are compatible at both ends of the link. For critical or long-term installations, verify link budget and margin to accommodate connector and splice losses.
