HSGQ 10G SFP+ Dual Fiber Module – Long-Distance Optical Networking from 20km to 120km

Not every 10 Gigabit fiber connection covers the same distance. A link between nearby distribution sites may require a 20km optical transceiver, while a much longer route demands different laser technology, receiver characteristics and a carefully planned optical power budget.

The HSGQ 10G SFP+ Dual Fiber Module is a family of high-speed optical transceivers designed for compatible 10 Gigabit Ethernet equipment. Available in distance-specific variants reaching up to 120km, the series supports single-mode fiber (SMF), LC Duplex connectivity and Digital Diagnostic Monitoring (DDM/DOM).

For ISPs, telecom operators and enterprise network engineers, these modules provide options for connecting switches and routers over different fiber distances without treating every optical link as an identical installation.

Choose the Optical Variant for Your Route

HSGQ offers multiple models in its SFP-10G-LR/ER/ZR series, with different distance ratings and operating wavelengths.

The manufacturer's published range includes:

These are different module options, not adjustable distance settings on a single transceiver.

HSGQ also lists other distance variants within the wider family. Before ordering, confirm the exact model code, laser type, optical power specifications and compatibility with the module installed at the opposite endpoint.

Two Fiber Strands for Full-Duplex 10G Transmission

The HSGQ 10G Dual Fiber SFP+ series uses an LC Duplex optical interface.

In a standard dual-fiber arrangement, one single-mode fiber strand carries transmitted data and the other carries received data. This allows simultaneous communication in both directions between compatible optical endpoints.

Unlike a single-fiber BiDi transceiver, this module family is designed for separate TX and RX paths.

The series supports an optical signaling rate of 10.3125Gbps, associated with 10 Gigabit Ethernet networking.

A compatible 10G SFP+ port is required at each network endpoint, together with appropriate single-mode fiber cabling and matching optical characteristics.

Optical Diagnostics That Support Maintenance

Long-distance fiber links can be affected by cable attenuation, dirty connectors, damaged splices and unsuitable optical power levels.

The HSGQ SFP+ module series incorporates DDM/DOM monitoring, allowing supported host equipment to retrieve available operating information from the optical transceiver.

Depending on the switch or router, this can help technicians examine transceiver temperature, optical signal levels and other diagnostic parameters.

These measurements are useful during commissioning and troubleshooting, although the exact monitoring information depends on device firmware and transceiver support.

The modules also feature a hot-swappable SFP+ design, allowing convenient installation and replacement in compatible networking equipment.

Optical Budget Comes Before Maximum Distance

A 120km-rated optical transceiver should not automatically be selected for every shorter fiber route.

Long-distance modules can have different transmitter power and receiver operating limits. Using an unsuitable optical module on a short link may result in excessive received optical power, while choosing an insufficiently powerful module for a long route may prevent the connection from working.

For each installation, evaluate:

• Fiber attenuation and actual route length

• Connector and splice insertion losses

• Transmit power and receiver sensitivity

• Receiver overload limits

• Engineering margin and endpoint compatibility

The manufacturer's advertised transmission distance is a rated capability under suitable optical conditions, not a guarantee for every installed network.

Suitable Applications Across Different Network Distances

ISP aggregation links: Connect compatible 10G network switches between distribution points and upstream networking facilities using suitable single-mode fiber.

Metro and long-distance Ethernet networks: Select a distance-specific transceiver for optical connections between separated network locations.

Enterprise backbone infrastructure: Establish higher-capacity uplinks between compatible routers or switches across large campuses and remote business facilities.

HSGQ lists compatibility with a range of networking platforms. However, the actual module must be checked against the host equipment's model, firmware and supported optical transceiver requirements.

The module family is intended for point-to-point Ethernet connections. It should not be confused with GPON/EPON OLT PON modules or single-fiber BiDi transceivers.
