Hisense Broadband compatible LTF8505-BC+ Description
EdgeOptic's LTF8505-BC+ compatible is a Hisense-coded version of the EdgeOptic 25G-SFP28-100 multi-vendor 25GBASE-SR SFP28 transceiver, a direct replacement for the Hisense Broadband LTF8505-BC+. The module ships with Hisense-recognized EEPROM, so hosts that validate against the Hisense LTF8505-BC+ identity read the module as the genuine part rather than flagging an unsupported transceiver event.
The module operates at 25GBASE-SR over duplex multimode fiber: 100 m on OM4/OM5, 70 m on OM3. The 850 nm VCSEL transmitter delivers −5 to +2.4 dBm, paired with a PIN receiver rated better than −10.3 dBm sensitivity, giving a 5.3 dB link budget. RS-FEC per IEEE 802.3by Clause 91 (RS(528,514)) is supported when enabled by the host port. Line signaling rate is 25.78125 Gbps. Power draw is 0.3 W typical, a measurable thermal saving relative to OEM modules spec'd at 1.0 W when an aggregation chassis is fully populated.
The LTF8505-BC+ is positioned for short-reach 25 Gigabit links over multimode fiber in carrier and ISP aggregation, mobile backhaul, and data center interconnect contexts. The EdgeOptic compatible is coded to the Hisense LTF8505-BC+ EEPROM identity; specify this SKU when the host platform validates against the Hisense part number. For host environments that validate against a different EEPROM identity, EdgeOptic also stocks vendor-coded compatibles for the same 25GBASE-SR optic across other OEM identities in the 25G-SFP28-100 product family.
The plus suffix in LTF8505-BC+ is Hisense's model revision notation. The physical optic (850 nm VCSEL, PIN detector, LC/UPC duplex connector, SFF-8472 DOM) is the same design family across the LTF8505 SFP28 line; the EEPROM programming is what differentiates the Hisense-coded LTF8505-BC+ SKU from other vendor-coded variants of the same optic. Cross-referencing between vendor-coded variants is only valid at the optical-performance level; the parts are not substitutable 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 C case (commercial). Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms.

Frequently Asked Questions
What is the difference between the Hisense LTF8505-BC+ and the LTF8505-BC-IN?
Both part numbers refer to 850 nm 25GBASE-SR SFP28 transceivers from the same Hisense Broadband LTF8505 product family. The difference is EEPROM coding. LTF8505-BC+ is coded for hosts that validate against the Hisense LTF8505-BC+ identity. LTF8505-BC-IN is the Intel-coded variant for Intel NIC platforms. The two part numbers are not interchangeable on hosts that enforce EEPROM validation. Specify LTF8505-BC+ for Hisense-coded host requirements; for Intel NIC-based servers see the LTF8505-BC-IN page for the platform-specific compatibility list.
What optical link budget can I plan with on OM3 and OM4 fiber?
The LTF8505-BC+ has a 5.3 dB optical link budget per IEEE 802.3by Clause 112. Reach is 70 m on OM3 and 100 m 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 in aggregation closets the reach ceiling is governed by modal bandwidth (fiber grade OM3 versus OM4) rather than attenuation against the power budget, so fiber grade determines the distance cap rather than fiber length against the link budget.
