The Finisar FTLF1436P3BCL is a 25G SFP28 short-reach (25GBASE-SR) multimode optical transceiver designed for data center top-of-rack and server-side connections over OM3/OM4 fiber. For IT procurement teams, resellers and system integrators deploying 25G Ethernet access layers, this module delivers consistent performance in short-reach environments where power and thermal budgets are critical. We supply this item in volume with batch-consistent stock, ensuring that modules within a single order ship from the same production batch to simplify qualification and rollout. As with all SFP28 modules, verify that your target switch and host platform support the required coding before deployment at scale.

Sourcing & Deployment Notes for Resellers and Integrators
- Platform compatibility: 25GBASE-SR SFP28 modules generally pair with 25G switch ports from vendors such as Cisco, Juniper, Arista, and Mellanox/NVIDIA families; brand coding may limit operation to certified platforms, so confirm firmware and module support lists before placing bulk orders.
- Product family positioning: within the Finisar SFP28 lineup, this SR (short-reach) multimode variant is the cost-effective option for in-rack and adjacent-rack links; longer runs require single-mode LR-class modules, which we can also quote for mixed-project orders.
- Link planning: given the 70 m (OM3) and 100 m (OM4) reach limits, audit the customer’s fiber plant (patch panels, OM grade) during project scoping and pair the deployment with LC duplex OM4 patch cords to stay within the link budget.
- Stock & consistency: regular stock is maintained for this SKU; when ordering multiple units, we confirm batch consistency so all modules in a shipment share the same manufacture date code — important for enterprise rollouts and staged deployments.
- Compliance: modules are supplied with CE, FCC and RoHS documentation available on request, supporting export and customs clearance for overseas B2B shipments.
Warranty coverage and RMA handling are provided for wholesale customers, with technical pre-sales support available to assist integrators during compatibility validation. Lead times are typically short for in-stock quantities, and we can arrange consolidated shipments or split deliveries for phased projects. For current stock levels, batch information and volume pricing, please request a wholesale quote.
