Optical transceivers (modules)

Optical transceivers are a key component of modern data transmission networks. Transceiver is an abbreviation of two English words: transmitter and receiver. In some cases, transceivers are also called optical transceivers or modules. Transceivers convert electrical signals into optical ones, providing stable and fast data transmission over the required distance (from several hundred meters to hundreds of kilometers). Some transceivers have an RJ-45 interface and are designed to connect a twisted pair. It is also worth paying attention to the fact that there are Active (AOC) and passive (DAC) cables. AOC and DAC are factory-terminated cables with non-removable transceivers with the required type of form factor installed at both ends. AOC and DAC can be either copper or optical. It should also be noted that AOC and DAC equipped with a QSFP (40G) transceiver on one side and 4ХSFP+ (4x10G) on the other are called “hydras”. In our catalog you can purchase SFP, SFP+, XFP, QSFP, QSFP28 modules and other formats with speeds up to 400Gbps and ranges up to 160 km, compatible with equipment from leading global manufacturers such as Cisco, Juniper, Huawei, HP, Arista and others.

Where are optical transceivers used

Optical transceivers are widely used in a variety of areas where high throughput and reliable data transmission are required.

DWDM and CWDM networks
Data centers and telecom providers
Ethernet backbone networks 1G/10G/40G/100G
Long-distance video surveillance
Mobile television stations
Video and audio equipment (directors' consoles)
Cloud infrastructure
Corporate and Campus Networks

Thanks to their versatility and wide choice of form factors, the transceivers can be easily integrated into both existing infrastructure and scalable network solutions.

How to choose the right transceiver

When choosing a transceiver, it is important to consider:

data transfer rate (1G, 10G, 25G, 40G, 100G, 400G);
fiber type (single-mode SMF or multi-mode MMF);
transmission range (from 100 m to 160 km);
compatibility with your equipment;
form factor and interface type (LC, SC, MPO);
availability of DDM monitoring;
required operating wavelengths.

Important!

For trunk solutions with EDFA amplifiers, DWDM SFP+ 10G ZR (80 km) or DWDM SFP 1.25G 160 km are often chosen – they are compatible with multiplexers and optical amplifiers.
