The 10Gbps transmission rate supports high-throughput data traffic across telecom core networks and regional aggregation routing systems. It helps network operators reliably transport large volumes of IP data between central offices and edge distribution nodes.
DWDM-SFP10G-56.55-80 Module with DWDM Technology for Fiber Efficiency
Dense Wavelength Division Multiplexing (DWDM) technology enables multiple optical channels to transmit simultaneously over a single fiber pair. This capability significantly increases existing fiber capacity and lowers the cost of deploying additional cables.
DWDM-SFP10G-56.55-80 Module with 1556.55nm Wavelength
A precise 1556.55nm operating wavelength corresponds to Channel 26 on the standard 100GHz ITU-T C-Band grid. The built-in cooled EML transmitter maintains strict wavelength stability and low spectral distortion during continuous operation.
Extended optical reach up to 80km over single-mode fiber makes the device ideal for long-distance point-to-point spans. An internal APD receiver provides high optical sensitivity to overcome signal attenuation across large fiber spans.

No, this module is strictly engineered for single-mode fiber. Firing a 1556.55nm narrow-band laser into multi-mode fiber causes severe modal dispersion and optical reflection issues, so standard SMF patch leads should always be used. by LINK-PP Technical Support
Generally, yes. It uses an integrated cooled EML laser designed specifically for the 100GHz ITU grid at 1556.55nm. As long as your switch cage stays within the standard 0 to 70C operating range, the internal controller typically keeps the center wavelength steady without bleeding into adjacent channels like C25 or C27. by LINK-PP Technical Support
In most standard scenarios with quality single-mode fiber, it should manage that span quite well. With an EML transmitter, APD receiver, and an optical design rated for up to 80km, a 68km link usually leaves adequate margin. However, it largely depends on actual link losses — such as dirty patches, patch panels, or high-loss splices — so checking your OTDR or power meter readings before turning up the link is always a good practice. by LINK-PP Technical Support
Yes, it is fully hot-pluggable according to the SFP+ MSA. You can slide it in or pull the bail latch to release it while the switch chassis is powered on. We simply recommend unseating the fiber cables first to avoid accidental bending or eye safety concerns. by LINK-PP Technical Support
Yes, it is well suited for wireless backhaul and fronthaul uplinks over single-mode fiber. The transceiver natively supports multirate transmission up to 10.7Gbps, making it capable of handling 10G Ethernet backhaul traffic as well as CPRI and eCPRI framing protocols, alongside standard 10GBASE-ZR line rates. by LINK-PP Technical Support
Built an offsite backup mirror connecting our main office SAN to a remote facility 68km away. Standard duplex LC patch cables plugged right in. Optical DOM parameters matched our inline optical power meter within 0.3dB tolerance. Outstanding link stability for mission-critical enterprise storage replication. :D

Running these inside our distribution rack at 0 to 70°C commercial temperature range. They handle peak day traffic smoothly. Stable TX power around +2dBm and the link margin is generous enough for our 70km spans. :-)
