Hisense Broadband LTF8503-BC Compatible 8Gb FC SFP+

Hisense Broadband LTF8503-BC is an 8Gb Fibre Channel short-wave SFP+ from the Hisense LTF series, a family that covers both 10GBASE-SR Ethernet and 8G FC variants on the same outer form factor. This BC-suffix part is a customer-specific EEPROM build from the Hisense-to-OEM channel, so the programmed vendor-name and vendor-OUI fields match the downstream OEM brand rather than a generic Hisense identifier, which is how Hisense tracks OEM-labelled inventory shipping into HPE, Dell, IBM and other storage partners. Electrically it is a FC-PI-4 SW optic (T11.3 INCITS 424-2007) running 8.5 Gbps with backward compatibility for 4G FC (4.25 Gbps) and 2G FC (2.125 Gbps) on OEM FC fabrics such as Brocade B-series directors and QLogic/Emulex HBAs. Platform support is driven by the EEPROM variant rather than the optics, so the same LTF8503 hardware ends up as several distinct OEM SKUs depending on the suffix.

Optical specs follow FC-PI-4 SW: 850 nm VCSEL source, 850 nm PIN detector, ~8.0 dB link budget, and standard reaches of 150 m OM3, 190 m OM4, 50 m OM2 and 21 m OM1 over duplex LC multimode fiber. The module carries SFF-8472 digital diagnostics for per-port TX power, RX power, bias current, voltage and temperature telemetry. EdgeOptic's compatible is coded to the BC EEPROM variant requested with order, so the part reports consistently on the target OEM switch or HBA. Operating range is 0 to 70 degrees Celsius, conforms to the SFP+ MSA (SFF-8431/8432), and is CE/RoHS certified. Hisense LTF series suffix conventions separate the optical build (LTF8503 for 8G FC, LTF8502 for 10G SR) from the EEPROM-coding tag (BC here, distinct from other LTF8503 suffixes), so matching the specific suffix to the target host is the key check when ordering spares.

If the target switch, director or HBA needs a specific BC-variant vendor code, a different OEM label than our default, or validation against a specific Fabric-OS or HBA firmware release, contact our sales team with the platform model and firmware so we can program the correct EEPROM before shipping.
