SKU CH-RQ1Q-JQHQJ

A 10GBase-LR SFP+ transceiver for single-mode fibre at 1310 nm reaching 1.4 km with an industrial temperature range of -40° to 85°C

  • 10GBase-LR speed up to 10.31 Gbps
  • Single-mode fibre reach up to 10 km
  • Industrial temperature range -40 to 85 °C
  • 1310 nm Tx/Rx wavelength for SMF
  • 6 dB optical budget for link margin

Hisense LTF1303-BH+ SFP+ module

The Hisense LTF1303-BH+ is a 10GBase-LR SFP+ transceiver built for single-mode fibre links in Hisense broadband equipment. It suits network engineers extending 10 Gbps connections over longer-haul fibre runs. Buyers needing multi-mode optics or third-party switch support should look elsewhere.

Distance and link budget limits

The module transmits at 1310 nm over single-mode fibre with a 6 dB optical budget and a 10 km reach specification. Signal loss beyond that budget or on mismatched fibre types will break the link. Installers must verify total insertion loss stays within the 6 dB margin.

Industrial temperature rating

Rated for -40 °C to 85 °C operation, the transceiver functions in uncontrolled cabinets or outdoor enclosures. Deployments in climate-controlled racks do not require this range. Without the industrial rating the part is unsuitable for harsh environments.

Highlights

  • 10GBase-LR speed up to 10.31 Gbps
  • Single-mode fibre reach up to 10 km
  • Industrial temperature range -40 to 85 °C
  • 1310 nm Tx/Rx wavelength for SMF
  • 6 dB optical budget for link margin

Questions about this item

Should I pick the 1.4 km or 10 km distance version of this Hisense LTF1303-BH+ module?

The module is rated for 10 km over single-mode fibre; the 1.4 km figure in the title appears to be a shorthand and the full specification supports the longer reach.

What does the 10.31 Gbps data rate mean when the module is installed in a live switch?

It supports any Ethernet or storage protocol running between 1.25 and 10.31 Gbps, so a 10 GbE link will operate at line rate without throttling.

How does the SFP+ interface and 1310 nm wavelength limit the cable plant I can use?

The LC duplex port requires single-mode fibre at 1310 nm; with a 6 dB optical budget you can run up to 10 km provided total link loss stays within that margin.
