C-LIGHT 32G BiDi SFP28 optical transceivers are designed for high-speed bidirectional communication over a single strand of single-mode fiber. Instead of dedicating separate fibers to transmit and receive directions, the BiDi architecture uses complementary optical wavelengths to carry two-way traffic through one fiber.
The series supports data rates up to 32Gb/s and provides 10km, 20km, and 40km transmission options. With an SFP28 form factor and LC optical interface, these modules provide a practical solution for high-bandwidth network links where available fiber resources need to be used efficiently.
The modules provide up to 32Gb/s optical connectivity for high-bandwidth data communication environments.
Transmit and receive traffic share one single-mode fiber, reducing the number of fiber strands required for a bidirectional optical connection.
Three transmission ranges are available to accommodate different distances between network nodes.
The available configurations include 1270/1330nm and 1290/1310nm wavelength combinations, with the corresponding reverse pair used at the opposite end of the link.
The product family is designed for SMF transmission, making it suitable for medium- and long-distance optical connections.
The compact SFP28 package supports high-density installation in compatible network equipment.
LC connectivity provides a standard duplex fiber interface for integration with compatible optical equipment.
The listed configurations are available with commercial and industrial case-temperature options.
The 32Gb/s interface can support data communication environments where higher optical throughput is required.
Single-fiber operation is particularly useful for network routes where only one available fiber strand can be allocated to a link.
The modules can provide optical links between compatible network devices within or between data center facilities.
10km and 20km configurations can be used for optical connections between enterprise network locations and aggregation equipment.
The 40km versions provide additional reach for network connections extending beyond typical local data center distances.
BiDi technology allows existing fiber infrastructure to be used more efficiently when expanding high-speed optical connectivity.
The main advantage of the BiDi architecture is its ability to provide bidirectional communication through one fiber strand, helping make better use of existing fiber infrastructure.
C-LIGHT provides complementary wavelength versions so that the two ends of a BiDi link can be selected as a matched transmission pair.
10km, 20km, and 40km versions provide a straightforward choice according to the physical distance of the optical link.
The SFP28 form factor allows 32Gb/s optical connectivity to be deployed in equipment where port density is an important consideration.
C-LIGHT states that the 32G BiDi SFP28 optical modules are compatible with switches from more than 100 brands.
C-LIGHT states that 100% of products pass initial testing, final testing, and factory inspection through a three-step quality-control process.
A 32G BiDi SFP28 optical transceiver is a high-speed pluggable module that transmits and receives data over the same single-mode fiber by using different optical wavelengths for the two directions.
C-LIGHT provides 10km, 20km, and 40km versions of the 32G BiDi SFP28 optical transceiver.
The product family includes 1270/1330nm and 1290/1310nm wavelength combinations. Reverse configurations are used to provide the complementary transmission direction.
Yes. The listed C-LIGHT configurations use single-mode fiber for 10km, 20km, and 40km transmission.
The 32G BiDi SFP28 configurations use an LC optical connector.
BiDi technology allows both transmission directions to share one fiber strand, which can improve fiber utilization when the available fiber resources are limited.
According to the C-LIGHT product page, the communication protocol complies with IEEE 802.3ae, the interface protocol complies with SFF-8431 and SFF-8432, and the packaging protocol complies with SFP+ MSA.
C-LIGHT 32G BiDi SFP28 optical transceivers combine 32Gb/s transmission with single-fiber bidirectional communication, providing a practical approach to high-speed networking where fiber availability is a consideration. With 10km, 20km, and 40km reach options, complementary wavelength configurations, SMF support, and LC connectivity, the series can be adapted to different medium- and long-distance optical network deployments.
