Cisco ONS-SC-2G-50.9 Compatible OC-48 SFP DWDM 1550.92nm 60km/100km Transceiver Module

Keeping an OC-48 circuit alive rarely justifies redesigning it, and the ONS-SC-2G-50.9 is built so no redesign is needed: it matches the Cisco original's 1550.92nm DWDM wavelength and its 60km/100km reach rating, and it occupies the same SFP slot. Single-mode fiber, LC/UPC connectors, and a 0 to 70°C operating range complete the like-for-like profile.

• Wavelength: 1550.92nm
• Connector: LC/UPC
• Fiber: SMF
• Operating temp: 0 to 70°C (32 to 158°F)

Swapping it in preserves the wavelength plan and the engineering assumptions the span was built on, which keeps maintenance windows short and paperwork unchanged. Outgoing test includes verification against the MSA specification. Backed by the GreenLights4Life® Limited Lifetime Replacement Warranty.
