Solitine 10G SFP+ LC Module Pair – 20km Single-Fiber 10G Networking
As network traffic grows, a standard Gigabit uplink can become a bottleneck between distribution switches, servers and separate network locations. Moving to 10 Gigabit Ethernet is one way to increase available link capacity, but long-distance fiber connections can also create challenges when spare fiber strands are limited.
The Solitine 10G SFP+ LC Module Pair addresses both requirements by combining 10GBASE-BX bidirectional technology with a rated optical reach of up to 20km. The pair uses one strand of single-mode fiber for transmission in both directions, making it suitable for compatible ISP distribution networks, enterprise backbone connections and building-to-building fiber links.
Unlike a conventional dual-fiber 10G optical transceiver, the Solitine BiDi pair operates through a single LC Simplex fiber connection at each end.
10G Uplink Without Using Two Fiber Strands
The main advantage of this module pair is its ability to establish a high-speed point-to-point connection over one optical fiber strand.
Instead of dedicating separate fibers for transmit and receive traffic, the two modules use complementary optical wavelengths to communicate simultaneously.
The pair is configured as follows:
Install Module A and Module B at opposite ends of the fiber link. Each module receives the wavelength transmitted by its partner, enabling bidirectional 10G communication through a single strand of single-mode fiber.
This configuration can help preserve fiber capacity across existing distribution routes where installing additional fiber would be costly or impractical.
Both ends must use the correct complementary wavelengths. Installing two identical wavelength configurations will not establish the intended BiDi connection.
Understand the 10G Performance and 20km Reach
The Solitine 10GBASE-BX SFP+ transceivers support an optical data rate of 10.3125Gbps, associated with 10 Gigabit Ethernet transmission.
The modules are designed for single-mode fiber (SMF) and use LC Simplex connectors, with a maximum rated transmission distance of 20km under suitable optical link conditions.
Manufacturer-published optical parameters include:
TX Optical Power: 0 to +5dBm
Receiver Sensitivity: -15dBm or better
Optical Interface: LC Simplex
Fiber Type: Single-Mode Fiber
Operating Temperature: 0°C to 70°C
When planning a 20km network link, technicians should evaluate the entire optical path, including fiber attenuation, connector insertion loss, splice loss and engineering margin.
The advertised distance is a rated optical reach rather than a guarantee that every 20km installation will operate successfully.
Similarly, the 10.3125Gbps optical line rate should not be interpreted as application-level throughput or guaranteed internet speed.
Where a 10G BiDi Pair Makes Sense
ISP distribution and aggregation: Establish a high-capacity fiber uplink between compatible 10G switches or routers while conserving available fiber strands.
Office and campus backbone: Connect separate buildings or network distribution points where a 10G link is required across an existing single-mode fiber route.
Data centre and enterprise interconnects: Use compatible 10G SFP+ equipment for dedicated point-to-point optical links when the distance and single-fiber arrangement match the deployment.
The hot-pluggable SFP+ form factor makes installation convenient in compatible networking equipment. Each module measures approximately 56.5 × 13.4 × 8.5mm and weighs around 22g.
Before installation, confirm that both host devices provide suitable 10G SFP+ ports and accept the required BiDi optical specifications.
Although Solitine lists compatibility with various networking platforms, actual operation depends on the equipment model, firmware and supported transceiver identification.
Important: BiDi SFP+ Is Not the Same as 10G SR, LR or EPON
Several optical transceivers use the SFP+ form factor, but they are not interchangeable.
A conventional 10GBASE-SR module generally uses multimode fiber for shorter links, while standard 10GBASE-LR modules commonly use single-mode fiber with separate transmit and receive fiber paths.
The Solitine 10G BiDi pair instead uses 1270nm and 1330nm complementary wavelengths over a single SMF strand, with one LC Simplex connector per module.
It should also not be confused with a 10G EPON OLT PON module, which serves a different optical access-network function.
For a compatible installation, the device port type, optical standard, connector arrangement and remote transceiver must all match the intended link.
