Supersuperuncle

Supersuperuncle 155M 40KM 1310NM SM ESFP single-mode optical module

SKU CH-A87H-6B0XC

A single-mode optical module supporting 155M data rate over 40km at 1310nm wavelength

  • Supports 40 km single-mode links at 1310 nm wavelength
  • Delivers 155 M data rate for compatible networks
  • Designed for WTD RTXM140-400 equipment integration
  • Brand-new condition ensures reliable optical performance

Compatible WTD RTXM140-400 module

This 155M 40KM 1310NM SM ESFP single-mode optical module is designed for the WTD RTXM140-400 platform. It serves network engineers and data-centre operators who need a drop-in transceiver for long-reach fibre links. The unit arrives new and ready for immediate deployment in compatible server or switch chassis.

Replaces legacy 155M short-reach optics

The module upgrades existing 155M connections that cannot span 40 kilometres, removing the need for intermediate repeaters. It is not suited for multimode fibre runs, higher-speed 140G or 400G lanes, or environments requiring CWDM or DWDM wavelength grids. Buyers needing greater bandwidth or different wavelength plans should select a separate part.

Highlights

  • Delivers 155 M data rate for compatible networks
  • Designed for WTD RTXM140-400 equipment integration
  • Brand-new condition ensures reliable optical performance

Questions about this item

What slot type does the 155M 40KM 1310NM SM ESFP module need?

It fits a standard SFP cage that accepts single-mode transceivers rated for 40 km at 1310 nm.

Which fibre connector must be cleaned and seated before locking the bail latch?

The LC duplex connector on the module face; the TX port uses the 1310 nm wavelength so the matching patch cord must be single-mode.
