Products and Services

RMH-Series and RMS-Series Super Raman* The Telecom ready subrack is a stand-alone rack-mounted unit, which operates virtually independently from the receiving terminal equipment. Its network-related plug-in units (PIUs) include: alarm and status monitor, fiber integrity monitor and safety shutdown (doubly redundant), and a network element interface. Each pump laser diode is mounted as a separate PIU. This feature is unique to MPB's Raman telecom subrack product line. It allows the "hot swap" of a laser diode PIU in the event of a laser diode failure. Applications for this system-ready, "plug and play" units include distributed Raman amplifications and remote EDFA pumping.

MPB Communications Inc.'s Raman Pump sources are available in two basic configurations: as a complete telecom-ready subrack or as a "flatpack" (see High-Power Raman Laser Flatpack).

High-Power Raman Telecom Subrack Module (RMH-Series)

• telecom-ready Raman pump modules with network interface and alarm and status monitor
• "hot-swap" individual pump diode cards for a dramatically lower overall FIT value
• fiber integrity monitor versions for both the C- and L- bands
• single or dual-wavelength versions available for both the C- and L- bands
• output powers up to 1.5 W

High-Power Super Raman* Telecom Subrack Module (RMS-Series)

• provides 2.0 to 2.5 dB extra margin improvement compared to conventional Raman pumping
• dual-wavelength Super Raman* pumping provides a broader gain spectrum than dual-wavelength conventional Raman
• uses a unique simplified Raman fiber laser based on a single Raman conversion
• single or dual-wavelength versions available for both the C- and L- bands
• "hot-swap" individual pump cards for a dramatically lower overall FIT value
• complete telecom-ready modules
