Specifications

Type: SFP optical module
Power budget: 21 dB
Part number: PXT-SFP-W35-40
Warranty: 1 year
Range: up to 40 km
Technology: WDM (single-fiber)
Wavelength: 1310 nm

The Pixietech SFP WDM module at 1310 nm with a range of up to 40 km is designed for building long single-fiber optical channels between remote sites. This solution is in demand among communication operators, large enterprises, and urban infrastructure projects where network nodes need to be connected over significant distances via existing single-mode fiber. The high 21 dB power budget ensures stable operation even on routes with appreciable losses.

Advantages

Range up to 40 km: covers distances between city districts or remote production sites
21 dB power budget: a large margin to compensate for losses on long routes with numerous connectors
WDM over a single fiber: efficient use of cable capacity without laying additional cable
1310 nm wavelength: paired with a 1550 nm module, forms a full duplex channel
Standard SFP: hot-swappable, broad compatibility with active equipment
1-year warranty: factory Pixietech quality

Applications

Backbone communication channels between city districts and remote sites
Connecting production enterprises to central offices over already-laid cables
Establishing backup channels in critically important security networks
Communication operator transport networks with long fiber routes

Frequently asked questions

What determines the range of exactly 40 km?

The range is determined by the module's power budget (21 dB) and the typical attenuation of single-mode fiber. On real routes, the final distance depends on cable quality and the number of splices and connectors.

Which module is installed at the other end of a 40 km route?

The partner module PXT-SFP-W53-40 with a 1550 nm wavelength. Together with this module, it forms a working WDM pair for duplex transmission.

Is an amplifier needed for a route up to 40 km?

When using quality single-mode fiber and observing loss norms, an amplifier is not required. If the 21 dB budget is exceeded, coordination with technical specialists will be required.
