Finisar compatible FTLF1436W4BTL Description
EdgeOptic's FTLF1436W4BTL compatible is a Finisar-coded drop-in replacement for the discontinued FTLF1436W4BTL, an industrial version of the EdgeOptic 25GFH-SFP28-10I multi-vendor 25G fronthaul LR SFP28 transceiver. It runs over duplex single-mode fiber with a duplex LC/UPC interface and carries a minimum guaranteed 8.3 dB optical budget, enough for a 10 km link on standard SMF cabling. The transmitter is a 1310 nm DFB laser paired with a PIN photodiode receiver, with TX output from −5 to +2 dBm and −13 dBm receiver sensitivity.
The module is multi-rate across 8.5 to 28.1 Gbps and supports CPRI option 7 (9.830 Gbps), option 8 (10.138 Gbps), option 9 (12.165 Gbps) and option 10 (24.33 Gbps), the CPRI ceiling for this rate, alongside eCPRI packetized over 25GBASE-LR and the 25GBASE-LR Ethernet rate of 25.78 Gbps. 25GBASE-LR operation needs host RS-FEC. DDM/DOM digital diagnostics report optical power, temperature, bias and voltage over the SFF-8472 interface. Typical deployments are mobile carrier networks, 5G fronthaul and O-RAN radio access links.
EdgeOptic's FTLF1436W4BTL compatible is an industrial-temperature module rated for a −45 °C to +85 °C operating range. EEPROM is coded so equipment expecting a Finisar FTLF1436W4BTL recognizes the module on insertion. It is compliant with 25GBASE-LR, IEEE 802.3cc, SFF-8431, SFF-8432, SFF-8472, the SFP28 MSA, CE and RoHS.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Made to order on a 2-week lead time with a lifetime warranty included. For volume pricing or coding questions, contact our sales team.
Frequently Asked Questions
The FTLF1436W4BTL is listed as discontinued. What replaces it?
The FTLF1436W4BTL is listed as discontinued, with the FTLF1436W4BTV as the current-production successor. The two share the same 25GE LR/eCPRI optical profile, so for a BTL-specified BOM you have two paths: EdgeOptic's FTLF1436W4BTL compatible drops straight into sockets that previously held the BTL, or you can move new builds to the FTLF1436W4BTV. Confirm the exact part marking your equipment expects before ordering.
