Hisense Broadband compatible LTF8505-BC+ Description
EdgeOptic's LTF8505-BC+ compatible is a Hisense-coded 25GBASE-SR SFP28 transceiver, a direct replacement for the Hisense Broadband LTF8505-BC+. It ships with Hisense-recognized EEPROM, so Hisense aggregation switches and OLT platforms identify the module as a native optic under standard module-identification policies.
The module operates at 25GBASE-SR over duplex multimode fiber: 100m on OM4/OM5, 70m on OM3. The 850nm VCSEL transmitter delivers -8.4 to +2.4 dBm, paired with a PIN receiver rated at -10.3 dBm sensitivity, giving a 5.3 dB link budget with host RS-FEC active (IEEE 802.3by Clause 108). Line rate spans 8.5 to 25.78 Gbps, so the same module supports both 10G and 25G SFP28 host ports. Power draw is 0.3W maximum, a measurable thermal advantage over OEM parts spec'd at 1.0W.
LTF8505-BC+ is positioned for Hisense Broadband switching and access equipment. The primary deployment pattern is ISP fiber-to-the-home aggregation, mobile backhaul, and carrier data center interconnect, where operators have standardized on Hisense-branded aggregation hardware. Buyers running Hisense-branded aggregation switches or white-label SFP28 hosts coded to the Hisense EEPROM target should specify this SKU. For Intel NIC deployments on Intel XXV710 or Intel E810 silicon, the correct variant is the Intel-coded LTF8505-BC-IN, a separate EdgeOptic part number.
The '+' in LTF8505-BC+ is Hisense model revision notation, not an Intel-coded suffix. The physical optic (850nm VCSEL, PIN detector, LC duplex connector, SFF-8472 DOM) is the same design family as Hisense's Intel-variant module, but the EEPROM programming differs. Cross-referencing between LTF8505-BC+ and LTF8505-BC-IN is only valid at the optical-performance level. The two cannot be substituted when host-side EEPROM validation is enforced.
DOM registers follow SFF-8472: transmit power, receive power, temperature, laser bias, and supply voltage are readable through the host switch CLI or any SNMP-based NMS. Operating temperature range is 0 to 70 degrees Celsius case (commercial). Every EdgeOptic LTF8505-BC+ is pre-tested on Hisense reference hardware before shipment.

Frequently Asked Questions
What is the difference between the Hisense LTF8505-BC+ and the LTF8505-BC-IN?
Both part numbers refer to the same 850nm SFP28 transceiver manufactured by Hisense Broadband. The difference is EEPROM coding. LTF8505-BC+ is coded for Hisense-branded switching and Hisense-ecosystem aggregation hosts, the typical deployment case for ISP aggregation and mobile backhaul. LTF8505-BC-IN is coded for Intel NIC platforms (Intel XXV710, Intel E810) and is sold by Intel as E25GSFP28SR. The two part numbers are not swappable on hosts that enforce EEPROM validation. Specify LTF8505-BC+ for Hisense platforms; specify LTF8505-BC-IN for Intel NIC-based servers.
Can the LTF8505-BC+ run at 10G on a dual-rate SFP+/SFP28 host port during an ISP aggregation upgrade?
Yes. The module's electrical interface supports 8.5 to 25.78 Gbps, so it operates at both 10GBASE-SR and 25GBASE-SR data rates. Set the host port to the lower speed, and disable RS-FEC for 10G operation (RS-FEC is specific to the 25G line rate). This is useful for ISP operators migrating aggregation uplinks in phases: the same Hisense-coded optic can stay in the chassis while downstream 10G feeds are cut over to 25G over time.
What optical link budget can I plan with on OM3 and OM4 fiber for FTTH aggregation runs?
With host RS-FEC active, the LTF8505-BC+ provides a 5.3 dB link budget. Reach is 70m on OM3 and 100m on OM4 or OM5. Connector and patch-panel losses count against the budget: a typical structured cabling run with two duplex LC patches and one cassette stays well inside the budget up to the MMF distance limit. On short MMF runs typical of FTTH aggregation closets, modal bandwidth rather than attenuation governs the reach ceiling, so fiber grade (OM3 vs OM4) determines the distance cap, not fiber length against the power budget.
