The Finisar FTLF1318P3BTL is an industrial-grade 1000BASE-LX SFP optical transceiver delivering 1.25 Gbps over single-mode links of up to 10 km on 9/125 μm SMF via a duplex LC interface. For resellers, system integrators and IT procurement teams, this is a high-turnover SKU for Gigabit Ethernet and 1G Fibre Channel backbone deployments in harsh or extended-temperature environments such as outdoor cabinets, factory floors and unconditioned equipment rooms. The -40°C to +85°C operating range is an industrial-grade rating — we recommend verifying that the host switch supports the full industrial temperature envelope before specifying it into a project bill of materials.
Product Overview for B2B Buyers
This module is stocked in volume for wholesale distribution. Units are supplied from consistent production batches, so integrators working on multi-site rollouts can expect uniform firmware coding and labeling across an order. Stock levels are confirmed at quotation stage, and partial shipments can be arranged for phased deployments.

Sourcing & Deployment Guidance
- As a 1310 nm LX-class module, it pairs with matched 1310 nm LX/SX-family optics on the far end and deploys between SFP ports on enterprise switches, routers, and media converters. Buyers should verify coding/compatibility with the end-customer’s switch vendor, since many platforms enforce vendor-locked or whitelisted transceivers — confirm coding requirements before placing bulk orders.
- Within Finisar’s SFP portfolio, this LX variant targets 10 km single-mode runs, whereas SX-class 850 nm modules are limited to multimode in-building distances. Stock planners should carry both classes to cover mixed fiber plants.
- Dual support for Gigabit Ethernet and 1G Fibre Channel makes this SKU reusable across LAN and SAN projects, improving inventory turn for resellers. When quoting against a customer BOM, verify the exact part number suffix, as suffixes denote coding and packaging variations.
- Export documentation (CE/FCC/RoHS declarations) is available on request for customs clearance and tender submissions. Warranty and RMA handling follows our standard wholesale terms, with dedicated support for channel partners.
