Hisense Broadband LTF8502-BC1 Compatible 10GBASE-SR SFP+

Hisense Broadband, an optics subsidiary of the Hisense Group, supplies 10GBASE-SR SFP+ modules in its LTF8502 series to several major networking OEMs on a private-label basis. The LTF8502-BC1 variant carries a customer-specific EEPROM profile, meaning the vendor fields and part number strings are coded for a particular host switch family rather than for generic deployment. EdgeOptic's compatible replicates that original profile so ports accept the module cleanly and report it as supported under show inventory commands on the target platform.

The optical layer follows IEEE 802.3ae Clause 52 for 10GBASE-SR. A 850 nm VCSEL transmitter feeds into dual LC on OM3 or OM4 multimode fiber, paired with a PIN photodiode receiver. Guaranteed minimum link budget is 6.1 dB, translating to 300 m over OM3 and 400 m over OM4; shorter OM2 runs are usable below roughly 82 m where modal dispersion remains manageable. Line rate covers 10.3125 Gbps for 10GbE, and the module reports link as up once the host PCS clears its 66b/64b sync watermark. DDM/DOM per SFF-8472 exposes Tx power, Rx power, bias current, case temperature, and supply voltage, with host-side polling intervals typically in the 1 to 10 second range on most switch platforms. Mechanical and electrical compliance is per SFF-8432, the module operates across the commercial 0 to 70 °C temperature range, and power draw sits below 1 W under nominal load. OM2 legacy plant will still link up, though reach is reduced — plan on roughly 82 m per IEEE 802.3ae Table 52-10 for OM2 class fiber.

Field engineers replacing Hisense-branded modules in existing deployments should note that BC1 coding is tied to a specific host profile; swapping to a generic LTF8502 will usually not power up on that same port. If the target switch rejects a module after installation, verify the vendor name and part number fields reported by show transceiver and reconcile against the host's supported optics list.
