Small rectangular XFP transceiver module with silver metal housing and single LC duplex port

Finisar Corporation

Finisar Corporation FTLX8511D3Product 10GBASE-SR XFP Transceiver

SKU CH-436W-P75M5 MPN FTLX8511D3Product

A hot-pluggable XFP transceiver delivers 10 Gigabit Ethernet over multi-mode fibre with LC duplex connectivity and digital diagnostics

  • Product typeXFP
  • 10 Gigabit Ethernet throughput for data networking
  • LC duplex connector links multi-mode fibre directly
  • XFP MSA compliance ensures broad switch compatibility
  • Digital diagnostics via 2-wire serial interface
  • Hot-pluggable form factor allows live module swaps

Finisar 10GBASE-SR XFP Transceiver

The Finisar FTLX8511D3 is a hot-pluggable XFP transceiver built for 10 Gigabit Ethernet links over multi-mode fibre. It complies with the XFP MSA and IEEE 802.3ae for 10GBASE-SR operation and supports 10G Fibre Channel at 1200-Mx-SN-I. Digital diagnostics are available through the standard 2-wire serial interface.

Suited for data-centre uplinks and storage links

Network engineers extending 10 GbE between switches or connecting servers to SAN fabrics will find the LC duplex connector and multi-mode support a direct fit. Buyers who need single-mode reach, longer-distance 10GBASE-LR, or a different form factor such as SFP+ should look elsewhere.

LC duplex multi-mode connector decides fit

The module presents one LC duplex port rated for 10GBASE-SR over multi-mode fibre. If the existing patch panel or switch port uses a different connector type or requires single-mode optics, this transceiver will not connect.

Questions about this item

How often should the LC duplex connector on the FTLX8511D3Product be inspected or cleaned to maintain link quality?

Inspect and clean the LC duplex connector whenever signal loss is detected or during scheduled fibre maintenance; the transceiver itself has no moving parts and requires no internal servicing.

What is the first limit reached when the FTLX8511D3Product runs continuously at 10 Gigabit Ethernet over multi-mode fibre?

The 10 Gb/s line rate and multi-mode reach are the primary limits; digital diagnostics via the 2-wire serial interface report temperature, voltage and optical power to warn before errors occur.

How much heat does the FTLX8511D3Product generate when it operates all day in a server chassis?

As a hot-pluggable XFP module it draws power from the host cage; typical XFP transceivers dissipate a few watts, so chassis airflow designed for XFP form factors keeps temperatures within spec.
