Overview

The Aerless SFP-IT-18230022-SM is a 25G SFP28 LR optical transceiver for single mode connections using duplex LC. Its 1310 nm DFB transmitter and PIN receiver support links up to 10 km. The module has a specified case operating temperature of −40°C to +85°C.

This LR option suits 25G Ethernet links between buildings or network sites where single mode fiber and the optical link budget support the required distance. It also supports CPRI option 10 and eCPRI applications. Clock and data recovery is built into both the transmitter and receiver, with maximum power consumption of 1.4 W.

Choose single mode or multimode

Choose this LR model for a single mode fiber link up to 10 km. For shorter OM3 or OM4 multimode links, compare the Aerless 25G SFP28 eSR, SFP-IT-18220021-MM, rated up to 200 m on OM3 or 300 m on OM4. The two models use different fiber types and wavelengths and are not a matched optical pair.

Diagnostics and monitoring

Digital Diagnostic Monitoring (DDM) uses the SFF-8472 interface to report module temperature, supply voltage, laser bias current, and transmitted and received optical power. Alarm and warning flags help identify values outside the configured operating limits. The host must support reading these diagnostics.

Compatibility and qualification

Switch coding is available for the intended platform. Send the switch or router model, software version and port configuration so we can confirm the appropriate coding before you order. A matching SFP28 slot alone does not establish compatibility.

Confirm the host’s supported line rate, FEC configuration and the optic at the other end of the link. The published reach is indicative; fiber condition, patch panels and connector losses affect the complete optical link. Share any qualification or test report requirements with your enquiry so the required evidence can be confirmed for your order.

What to include in your enquiry

• Part number, quantity and intended delivery date.
• Host manufacturer, model, software version and port mode.
• Fiber type, link length, far end optic and expected module case temperature.
• Required coding, FEC configuration and any qualification requirements.
• Delivery location in the United States or Canada.
