Product Overview
The SFP-10G-LR (Huawei part number 02310QDJ) implements 10.3125 Gbit/s 10GBASE-LR transmission at a 1310 nm center wavelength over singlemode fiber. Huawei hardware descriptions specify a 10 km target distance on G.652 SMF, maximum Tx power of +0.5 dBm, minimum Tx power of -8.2 dBm, a minimum extinction ratio of 3.5 dB and receiver sensitivity of -12.6 dBm.
The module uses an LC duplex connector in the standard SFP+ footprint and a 0°C to +70°C commercial case temperature range. It is the workhorse 10G singlemode module for links that leave the data hall: between buildings, across a campus, or to a carrier meet-me room.
Typical applications include 10G uplinks and metro-access spans between Huawei switches and routers over dark fiber, point-to-point links up to 10 km, and connections to DWDM/OTN transport equipment in the same building.
