Axiom 3HE11245AB-AX SFP transceiver 1000BASE-BX80-D TX 1550nm RX 1490nm 80km

SKU CH-15EG-D2XRX MPN 3HE11245AB-AX

Single-fibre SFP transceiver delivers 1 Gbps over 80 km using TX 1550 nm and RX 1490 nm wavelengths

  • 1 Gbps data rate for high-speed network links
  • Single-fibre BX optics TX 1550 nm RX 1490 nm
  • 80 km reach on single-mode fibre
  • LC duplex connector for standard patch panels
  • Designed for Alcatel 3HE11245AB downstream compatibility

1000BASE-BX80-D downstream SFP transceiver

The Axiom 3HE11245AB-AX is a small form-factor pluggable module built for 1 Gbps Ethernet over single-mode fibre. It operates as the downstream side of a bidirectional link, transmitting at 1550 nm and receiving at 1490 nm through an LC connector. The module supports distances up to 80 km and is coded for Alcatel equipment compatibility. It is supplied new with a limited lifetime warranty.

Who this suits and who should look elsewhere

Network engineers extending a point-to-point fibre run to 80 km with matched upstream modules will find the correct wavelength pair here. Buyers needing a different reach, the upstream TX 1490 nm/RX 1550 nm counterpart, or multi-mode fibre support cannot use this module. It is also unsuitable for 10 Gbps or higher line rates.

Deciding specification — 80 km single-mode reach

The 80 km maximum transfer distance on single-mode fibre is the parameter that determines whether this transceiver fits the link budget. If the span is shorter or longer, or if the fibre type differs, a different module is required. The fixed TX 1550 nm / RX 1490 nm wavelength pair must match the opposite end exactly.

Questions about this item

Does the 1550 nm TX laser on this Axiom 3HE11245AB-AX SFP run hot when powered 24/7?

The module draws less than 1 W in normal operation, so it stays cool inside a standard SFP cage with ordinary chassis airflow.

What patch-cord and switch port do I need to plug this 1490 nm RX SFP straight in?

A duplex LC single-mode patch cord and any SFP port that supports 1000BASE-BX80-D optics will work.

Will this 80 km downstream transceiver link with my older 1000BASE-BX80-U upstream module?

Yes — the TX 1550 nm / RX 1490 nm wavelength pair is designed to interoperate with the matching upstream unit.
