Description
Product Overview
The EtherWAN EX-LS48-C3U-TC-N-EB is a non-hardened Gigabit SFP transceiver for long-distance connections over 9/125 µm single-mode fiber. It supports a manufacturer-rated 70 km optical link using 1550 nm transmission and a duplex LC connector. Digital Diagnostic Monitoring (DDM) provides optical operating information through compatible network equipment. Confirm host support, far-end optics and fiber path loss before ordering.
The EtherWAN EX-LS48-C3U-TC-N-EB is a 1GbE, non-hardened SFP optical transceiver listed by Coremicro. EtherWAN specifies a 70 km distance, 9/125 µm single-mode fiber, duplex LC connector, 1550 nm wavelength, DDM, 23 dB optical link budget, 0 to +5 dBm transmitter output and -23 dBm receiver sensitivity. Operating temperature is 0°C to +70°C. A historical EtherWAN end-of-life notice identifies this part as a replacement model for older SFPs; that notice does not establish an end-of-life date for this model. Coremicro lists it as Special Order; verify current pricing, availability and warranty coverage before purchasing.
70 km Single-Mode Fiber Reach
The 70 km Gigabit SFP rating supports long-distance Ethernet links over 9/125 µm single-mode fiber. Actual reach depends on fiber attenuation, connector and splice losses, and the available optical link budget.
1550 nm Optical Transmission
This module uses a 1550 nm wavelength for its duplex LC optical interface. Match the remote transceiver and the entire fiber path to the planned wavelength and transmission distance.
Duplex LC Gigabit SFP Interface
A duplex LC connector provides separate transmit and receive fiber paths. Check the host Gigabit SFP slot, port compatibility and fiber polarity before installing the module.
Digital Diagnostic Monitoring (DDM)
DDM support allows compatible switches and media converters to show available optical diagnostic readings. The host platform determines which measurements are accessible.
Non-Hardened 0°C to +70°C Operation
The TC version has a commercial operating temperature range of 0°C to +70°C. Sites requiring -40°C to +85°C operation should evaluate the separately rated TI model.
23 dB Optical Link Budget
EtherWAN lists 0 to +5 dBm transmit output and -23 dBm receiver sensitivity, with a 23 dB link budget based on matching modules. Confirm total loss and adequate optical margin for each planned link.

What is the EtherWAN EX-LS48-C3U-TC-N-EB used for?
The EtherWAN EX-LS48-C3U-TC-N-EB is a non-hardened Gigabit SFP transceiver for long-distance links over 9/125 µm single-mode fiber. It uses duplex LC connectors and has a rated reach of 70 km.
How far can this EtherWAN SFP transmit?
This EtherWAN SFP is rated for a 70 km single-mode fiber link. Actual reach depends on total optical path loss, available margin and compatibility with the connected equipment.
Does the EX-LS48-C3U-TC-N-EB support DDM?
The EX-LS48-C3U-TC-N-EB supports Digital Diagnostic Monitoring (DDM). Diagnostic measurements are accessible when the host switch or media converter supports them.
Which wavelength and connector does the module use?
The module uses 1550 nm optical transmission and a duplex LC connection over 9/125 µm single-mode fiber. Verify the far-end optic, connector arrangement and optical budget before deployment.
What is the difference between the TC and TI versions of this EtherWAN SFP?
The EX-LS48-C3U-TC-N-EB is a non-hardened 0°C to +70°C module, while the EX-LS48-C3U-TI-N-EB is a hardened -40°C to +85°C model. Both are listed for 70 km single-mode fiber, 1550 nm optics, duplex LC and DDM.
Was the EX-LS48-C3U-TC-N-EB discontinued in 2014?
EtherWAN’s historical end-of-life notice lists the EX-LS48-C3U-TC-N-EB as a new replacement model, not an old model being discontinued in 2014. The last-buy and last-shipment dates in that notice refer to the older models; confirm present availability with Coremicro.
Is Coremicro an authorized EtherWAN dealer?
Coremicro displays an Authorized Dealer designation on its listing for this EtherWAN SFP module. Buyers should confirm current dealer status, order eligibility and manufacturer warranty coverage with Coremicro.
