About the Cisco 15454-GBIC-55.7
The Cisco 15454-GBIC-55.7 is a hot-swappable GBIC 1000BASE-DWDM ITU ch 27 optical transceiver for 1 Gbps Ethernet links over single-mode fiber, with an SC interface and reach of up to 120 km unamplified. Cisco description: ONS 15454 DWDM GBIC 1000BASE-DWDM 100 GHz, 32-channel grid. Cisco IOS XE, NX-OS, IOS XR and ONS software read the Cisco coding at insertion, so a genuine module avoids 'unsupported transceiver' messages. Typical uses: Gigabit uplinks, campus and inter-building fiber, access and WAN hand-off links on Cisco ONS 15454 MSTP / NCS 2000, NCS 1000 and NCS 4000 optical-transport cards.

What is the maximum distance of the 15454-GBIC-55.7?
Cisco documentation lists the 15454-GBIC-55.7 for 100-120 km unamplified / up to 300 km amplified (Cisco guide).
Which fiber and connector does the 15454-GBIC-55.7 need?
The 15454-GBIC-55.7 uses an SC connector on single-mode fiber (OS2). Wavelength: DWDM 1555.75 nm (ch 27). Both ends of the link must use the same optical standard. CWDM / DWDM optics must match the channel of the mux / demux port and the far-end module.
Which Cisco devices support the 15454-GBIC-55.7?
The 15454-GBIC-55.7 is documented for Cisco ONS 15454 MSTP / NCS 2000, NCS 1000 and NCS 4000 optical-transport cards. Support depends on the exact chassis, line card and software release; send us your device model and release and we confirm it against Cisco's documentation before dispatch.
Is the 15454-GBIC-55.7 still available?
Cisco has announced end-of-sale for the 15454-GBIC-55.7. Next Gen Networks sources genuine new and surplus stock on request; tell us the quantity and we confirm availability or quote the current Cisco equivalent.
Is your 15454-GBIC-55.7 genuine Cisco?
Yes. Next Gen Networks supplies original Cisco parts, not third-party lookalikes or grey-market stock. Every unit is checked before dispatch and we share serial numbers on request so you can verify them in 'show inventory' / the transceiver page.
