Solitine SOL-1SFP-LC – Extend Your Gigabit Network Over Single-Mode Fiber

A network connection between two buildings, an ISP distribution point and a remote switch, or separate sections of a large facility may need to travel much farther than an ordinary Ethernet cable can reach.

The Solitine SOL-1SFP-LC 1.25G SM LC 20KM Fiber SFP Module (Pair) is designed for this type of wired networking requirement. It provides optical connectivity over single-mode fiber, supporting a 1.25Gbps signaling rate and an advertised transmission distance of up to 20 kilometres.

Supplied as a pair, these compact SFP transceivers are suitable for connecting compatible Gigabit SFP equipment across a dedicated fiber link.

Why the 20KM Single-Mode Design Matters

Copper Ethernet cables are suitable for many connections inside a building, but longer distances often require optical fiber.

The SOL-1SFP-LC is intended for single-mode fiber (SMF), which is commonly used for longer optical network links. Its advertised 20KM transmission capability makes it relevant to ISP distribution, campus networking, office-building interconnections and other long-distance Gigabit Ethernet applications.

The 20KM figure is the module's rated reach, not a guarantee that every 20KM fiber route will operate successfully. Cable quality, splices, connectors, attenuation and the available optical power budget must all be considered.

For a shorter network connection, this module can also be used where the host equipment and optical conditions are compatible.

What Comes with the Pair?

The product is listed as a pair of SFP modules, intended for use at opposite ends of a fiber connection.

Each transceiver fits into a compatible SFP interface on supported networking equipment. The modules use LC Duplex optical connectivity, designed for a two-fiber transmit-and-receive arrangement.

This matters when ordering fiber patch cords. A duplex optical transceiver generally requires an appropriate two-strand fiber path, rather than the single-strand arrangement used by BiDi modules.

If your installation has only one available fiber strand, consider a suitable single-fiber BiDi SFP pair instead of assuming these two types are interchangeable.

Gigabit Performance Without a 10G Upgrade

Although the module is marketed as 1.25G, this refers to the optical signaling rate commonly associated with Gigabit Ethernet transceivers.

It should not be mistaken for a 10Gbps SFP+ module or a guarantee of 1.25Gbps usable network throughput. For compatible equipment, it is intended for Gigabit-class optical networking.

This makes the SOL-1SFP-LC particularly suitable when your switches or routers already provide 1G SFP slots and the main requirement is extending connectivity over fiber rather than increasing the Ethernet link speed.

Installation and Compatibility Considerations

Before installing the Solitine SOL-1SFP-LC, check that both devices support the required 1G SFP transceiver type and LC Duplex single-mode fiber connection.

Vendor compatibility also matters. Some managed switches and routers apply their own optical module compatibility requirements, even when a transceiver fits physically into the SFP slot.

For proper deployment, technicians should confirm the module's operating wavelength, optical budget, host-device support and the available fiber connection. The supplied product specification does not explicitly confirm the optical wavelength, so it should be verified before purchasing for a wavelength-sensitive deployment.
