Things to Know Before Selecting CWDM SFP Transceivers

As an extension of wavelength division multiplexing (WDM), coarse wavelength division multiplexing (CWDM) is a technology that multiplexes a number of optical carrier signals onto a single optical fiber through the use of different wavelengths (i.e., colors) of laser light. A CWDM SFP (Small Form-factor Pluggable) transceiver is a hot-swappable input/output device that plugs into an SFP port or slot of a switch or router, linking the port with the fiber-optic network. It is a  kind of optical-electric/electric-optical converter. With the transmitter on one end, the CWDM SFP transceiver takes in and converts the electrical signal into light, after the optical fiber transmission in the fiber cable plant, the receiver end again converts the light signal into electrical signal. The following figure shows the CWDM SFP transceiver in the CWDM system. In the figure, TX represents “transmit”, RX represents “receive”. Being a kind of compact optical transceiver, CWDM SFP transceiver is widely used in optical communications for both telecommunication and data communication. It is designed for operations in Metro Access Rings and Point-to-Point networks using Synchronous Optical Network (SONET), SDH (Synchronous Digital Hierarchy), Gigabit Ethernet and Fibre Channel networking equipment.

Three Components of CWDM SFP Transceivers

The CWDM SFP transceiver consists of an un-cooled CWDM Distributed Feed Back (DFB) laser transmitter, a PIN photodiode integrated with a Trans-impedance Preamplifier (TIA) and a Microprogrammed Control Unit (MCU). The DFB laser used in the CWDM SFP transceiver transmitter is a 18 CWDM DFB wavelengths laser. It is well suited for high capacity reverse traffic. Obeying the standard diode equation for low frequency signals, The PIN photodiode has a 80km transmission distance. And the MCU is a high-speed, executive, input-output (I/O) processor and interrupt handler for the NRL Signal Processing Element (SPE).

Advantages of CWDM SFP transceivers

Using existing fiber connections efficiently through the adoption of active wavelength multiplexing, CWDM SFP transceivers have improved the designs of telecommunications devices and other technologies. Here are some advantages of CWDM SFP transceivers:

  • Scalability and Flexibility—CWDM SFP transceivers can support multiple channels. It means that more channels can be activated as demand increases. CWDM SFP transceivers have a wide variety of network configurations that range from the meshed-ring configurations to the multi-channel point-to-point. In point-to-point configurations, the two endpoints will connect directly through a fiber link, allowing users to add or delete as many as eight channels at a time.
  • Low Risks in Investment—Most CDWM SFP transceivers have a low failure rate, which is less likely to be the reason why the user’s solution fails. It helps enterprises increase the bandwidth of the Gigabit Ethernet optical infrastructure without adding any additional fiber strands and can also be used in conjunction with other SFP devices on the same platform. Thus the user will be able to re-invest the capital saved by avoiding prematurely failed devices.
Selecting a Right CWDM SFP Transceiver

There are many kinds of CWDM SFP transceivers in the market. Their wavelengths are available from 1270 nm to 1610 nm, with each step 20 nm. Different CDWM SFP transceivers have different color codes, distances, date rates and laser operating wavelengths. For example, the CWDM-SFP-1470, which is colored gray, is one of Cisco CWDM SFP. It is a CWDM SFP transceiver that rates for distances up to 80 km and a maximum bandwidth of 1Gbps, operating at 1470nm wavelength. Customers may choose a CWDM SFP transceiver in accordance with their actual needs.

Applied to the access layer of Metropolitan Area Network (MAN), CWDM is a low-cost WDM transmission technology. Fiberstore provides the aforesaid CWDM-SFP-1470 and other types of CWDM SFP transceivers, which are convenient and cost-effective solution for the adoption of Gigabit Ethernet and Fibre Channel in campus, data center, and metropolitan-area access networks.

Cisco SFP and SFP+ Transceiver Modules Installation Guide

Cisco is one of the worldwide major fiber optic network equipments provider, the networking engineers may time and again facing the problems of install fiber optic transceivers to other Cisco devices for optical signal transmission. This article provides the installation instructions for Cisco small-factor pluggable (SFP) and SFP+ transceiver modules. These modules are hot-swappable input/output (I/O) devices that plug into 100Base, 1000Base and 10Gbase ports, to connect the module ports with the fiber optic or copper network.

Cisco SFP+ transceiver modules installation is the combination of Cisco original SFP+ or compatible Cisco SFP+ transceiver modules with your Cisco devices. Each port must match the wavelength specifications on the other end of the cable and that the cable must not exceed the stipulated cable length for reliable communications. Using only Cisco or compatible Cisco SFP+ transceiver modules on your own Cisco devices, as it allows a Cisco switch or router to identify and validate that the transceiver modules is certified and tested by Cisco.

Take SFP module for example, let’s discuss the installation guid and note.
To begin the installation, tools you need is listed below:
Wrist strap or other personal grounding device to prevent ESO occurrences
Antistatic mat or antistatic foam to set the transceiver on
Fiber optic end-face cleaning tools and inspection equipment.

SFP transceiver module have three types of latching devices to secure an SFP transceiver module in a port socket: mylar tab latch, actuator button latch, bail clasp latch. Knowing which type of latch your SFP transceiver module uses is crucial before the installation.

Disconnect all fiber optic cables before the installation
Attache an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metal surface on your chassis.
Removing the SFP transceiver module from its protective packaging.
Check the label on the SFP transceiver module body to verify that you have the correct model for your network.
Find the send (TX) and receive (RX) markings that identify the top side of the SFP transceiver module.
Position the SFP transceiver module in front of the socket opening. Different Cisco devices have different SFP module socket configurations. Your Cisco device could have either a latch-up or a latch-down orientation. Ensure that you are installing the SFP transceiver module in the correct orientation for your Cisco device.
Insert the SFP module into the socket until you feel the connector latch into place.
Press the SFP into the slot firmly with your thumb to ensure that the transceiver is properly latched in the socket.

After the installation steps above, the verification is needed. Grasp the SFP and try to remove it without releasing the latch. If the SFP can not be removed, it is installed and seated properly. If the SFP can be removed, you need to re-insert it and press harder with our thumb, repeat it until it is latched securely into the socket.
