Types of Pluggable Fiber Optic Transceivers

Pluggable Fiber Optic TransceiversPluggable fiber optic transceivers are user-friendly and recommended for use in telecommunications and data communications solutions. Many designers have often sought after these devices to improve functionality in designs. They are capable of plugging into a device without powering down, which makes upgrades easier. Downtime is minimal if a replacement is necessary for failed transceivers.

This solution interfaces well with a network device motherboard, which is supported by many network vendors. SFP (small form-factor pluggable) transceivers are known for supporting SONET, Fibre Channel, and gigabit Ethernet. A multi-service agreement (MSA) has been established to regulate or define commonality for pluggable transceivers. They are flexible, but they may be more expensive than average transceivers. Here are some of the different types of pluggable fiber optic transceivers that may be beneficial to your organization.

1. GE GBIC (Giga-Bit Interface Converter) Modules
These modules were some of the first pluggable fiber optic transceiver modules in the industry, and some of the most popular today. Transceivers were commonly used in Ethernet switches. These modules usually operate within wavelengths of 850nm to 1550nm and are compatible with many other devices. When shopping for multi-mode fiber, the modules will be designated LX, EX, BX, EZX or ZX depending on the distance.

2. WDM GBIC
The is one of the most cost effective modules, and it is recommended for single strand fiber optic applications from 10km to 60km. The device is operational with wavelengths of 1310nm, 1490nm, and 1550 nm. It’s versatile and is capable of compatibility with active equipment including routers, Ethernet switches, and other types of networking equipment.

3. Copper GBIC
Copper GBIC modules have a foundation based upon the GBIC multi-source agreement (MSA) and feature 100m transmission along with 1000 BASE-T standards. The pin designations are easy to use. For instance, in the past, many customers have used the RX_LOS pin for link indication. Some copper GBIC modules feature the RX_LOS pin internally grounded, which means that it does not have the link indication feature. Many copper GBIC modules are compatible with 1000 Base-X auto negotiation. The hot-pluggable copper GBIC modules are enclosed in a metallic encasing to yield a lower power dissipation and lower EMI.

4. CWDM GBIC Transceiver
These types of transceiver modules are cost effective and support a dual data-rate up to 1.25 Gbps. The transmission distance will reach up to 80km and is compatible with other CWDM devices such as those made by Cisco. If a switch-to-switch interface is required, try a CWDM GBIC transceiver. They also are recommended for switched backplane applications, optical transmission systems applications, or router/server interface applications.

Know the Different Types of Pluggable Fiber Optic Transceivers
Designers need to be aware of the types of pluggable fiber optic transceivers to ensure that they have the proper device for their design. The different options are enough to improve the flexibility in design. If you want to know about the different types of pluggable fiber optic transceivers, experts can help you, or you can perform your due diligence online.
