Installation of an SFP+ Transceiver

SFP+ transceivers are popular hot-swappable input and output enhancement components that allow 10 gigabit connections. They are often used to connect a device motherboard to other equipment. To apply SFP+ transceivers to your applications, other than choosing a proper one, you also need to know how to instore and remove an SFP+ transceiver. This article will help you select, install, and remove SFP+ transceivers.

Selecting an SFP+

Before installing an SFP+ transceiver, first you have to select the appropriate transceiver to provide the required reach. How to select an appropriate SFP+ transceiver? There are two key points. One is to determine the required reach. Depending on the applications, you can obtain SFP+ transceivers for cable distances of up to 15m, 300m, 10km, and so on. The other is to determine wavelength restrictions or requirements. Different types of SFP+ transceivers are available to meet the wavelength requirements, like 10GBASE-SR SFP+, 10GBASE-LR SFP+, 10GBASE-LRM SFP+ and 10GBASE-ER SFP+. Usually, an SFP+ transceiver has a label on the top and bottom or side of it. The label will tell you some basic information about the transceiver and make it convenient for you to know whether you’re installing the right one. For example, a picture of Finisar FTLX8571D3BCL compatible SFP+ transceiver is shown below. From the label, you can see that it is a 10GBASE-SR SFP+ transceiver.

Installing an SFP+

Procedures for installing an SFP+ transceiver:

  • 1. Remove the SFP+ transceiver from its protective packaging.
  • 2. Grasp the SFP+ transceiver between your thumb and forefinger.
  • 3. Insert the SFP+ transceiver into an SFP+ slot on the switch, applying a light pressure to the SFP+ transceiver until the device clicks and locks into position. SFP+ transceivers are keyed to prevent incorrect insertion. If the SFP+ resists pressure, do not force it; turn it over, and reinsert it.
  • 4. Remove the dust cover from the SFP+ optical bores and insert the fiber optic cable.
Removing an SFP+

Remove an SFP+ transceiver to replace it or to commission it elsewhere:

  • 1. Disconnect the network fiber optic cable from the SFP+ connector.
  • 2. Affix dust covers over the fiber optic bore and connector.
  • 3. Pull the swing-down latch handle and use it to extract the module.
  • 4. Pull and slide the SFP+ transceiver out of the SFP+ slot. If the SFP+ does not slide out easily from the slot, use a gentle side-to-side rocking motion while firmly pulling the SFP+ from the slot.
  • 5. Store the SFP+ transceiver in a safe place until needed.
Notes for Installation

During the process of installing and removing an SFP+ transceiver, there are several things that you need to keep in mind:

  • 1.SFP+ transceivers are similar to SFP transceivers in physical appearance but SFP+ transceivers support 10 gigabit per second (Gb/s) connections. Do not install an SFP+ transceiver in an SFP slot. The two transceivers look the same but function differently. You must ensure that your switch supports SFP+ transceivers before installation or use.
  • 2.SFP+ transceivers and XFP transceivers both support 10 Gb/s connections, but are not compatible devices. Do not install an SFP+ transceiver in an XFP slot. You must ensure the slot is an SFP+ slot before installation.
  • 3.Verify that the SFP+ is the correct model for your network configuration.
  • 4.Before you install the optical connector, ensure it is clean.
  • 5.Risk of eye injury by laser. Fiber optic equipment can emit laser or infrared light that can injure your eyes. When installing or removing an SFP+ transceiver, never look into an optical fiber or connector port. Always assume that fiber optic cables connect to a light source.
  • 6.To prevent damage from electrostatic discharge, always wear an antistatic wrist strap connected to an ESD jack.

SFP+ AOC Assemblies — A Preferable Interconnect Solution for SFP+ Applications

Dramatically reducing 10G interconnectivity costs, the 10G SFP+ cables can provide inexpensive and reliable 10G speed connections using either SFP+ copper cables or SFP+ active optical cables (AOCs). SFP+ AOC is a cabling technology that accepts the same electrical inputs as a traditional copper cable. It uses optical fiber and electrical-optical conversion on the cable ends to improve speed and data transmission distance of the cable while not sacrificing compatibility with standard electrical interfaces. Nowadays, SFP+ AOC has been a preferable interconnect solution for SFP+ applications. Before choosing it for your applications, you need to have a basic understanding about it.


AOC consists of multimode optical fiber, fiber optic transceivers, control chip and modules. SFP+ to SFP+ active optical cable is composed of SFP+ optical transceivers in both ends and fiber optic cable in between. This integrated optical module solution removes the complicated optical fiber interface and brings friendly and intuitive electrical-to-electrical interface to users. SFP+ AOC is designed to meet the requirements of high speed, high density and low power consumption for applications in today’s data centers via optical fiber wire. SFP+ AOC is compliant to industrial standard SFP MSA and provides high performance SFP+ interfaces, supporting 10Gb/s bi-directional operation. The demand for more bandwidth for data center is challenging interconnect technologies like Ethernet, Infiniband, and Fibre Channel. SFP+ AOC is one of the best solutions to solve this problem. The image below shows a Cisco SFP-10G-AOC10M compatible SFP+ to SFP+ AOC. It is a 10Gb/s, hot pluggable active optical cable for Ethernet data transmission.

Compared to SFP+ copper cables for data transmission, SFP+ AOCs provide more advantages, as shown below:

  • Longer reach
  • Lower weight and tighter bend radius enable simpler cable management
  • Thinner cables allows better airflow for cooling
  • Lower power consumption
  • No need for power-hungry conditioning ICs on the host board

SFP+ active optical cable is a 10Gbps and cost effective solution for 10G Ethernet (10GbE) applications. With industry-leading VCSEL technology and an advanced new light engine design, the SFP+ AOC assemblies are ideal for high-performance computing clusters, 10G Ethernet applications (10GbE), 4G and 8G Fiber Channel applications (4GFC/8GFC), 1x InfiniBand QDR, DDR, SDR, servers, switches, storage and network interfacing applications.
