SFP‑TD48T5‑10DxP 25G SFP28 10km Tunable DWDM Transceiver

The SFP‑TD48T5‑10DxP series is high‑performance 25G SFP28 tunable DWDM transceiver, available in two variants: SFP‑TD48T5‑10DCP (commercial 0‑70℃) and SFP‑TD48T5‑10DIP (industrial ‑40~+85℃). It supports dual‑rate 24.33024Gbps CPRI‑Option10 and 25.78125Gbps eCPRI, compliant with SFP28 MSA standard. Covering total 48 DWDM channels on 100GHz ITU‑T C‑Band grid (191.35‑196.1 THz), it features auto wavelength‑tuning capability. Achieves up to 10‑kilometer transmission over G.652 single‑mode fiber, duplex LC receptacle, real‑time DDM / DOM digital diagnostic via I2C interface. Single +3.3V power supply with max power consumption 3W, RoHS‑2 compliant, meets Class‑I laser safety. Perfect fit for 5G CPRI/eCPRI fronthaul, DWDM aggregation networks, switches and routers optical port deployment.

Frequently Asked Questions

Q: What does auto‑tuning function mean for this tunable DWDM module?

A: Auto‑wavelength tuning allows the transceiver to lock to target ITU‑T DWDM channel without manual wavelength configuration, greatly simplifies DWDM network provisioning and inventory management for operators.

Q: What is the difference between DCP and DIP part numbers?

A: SFP‑TD48T5‑10DCP = commercial temperature grade (0‑70℃ for climate‑controlled indoor sites). SFP‑TD48T5‑10DIP = industrial wide‑temperature grade (‑40~+85℃), for outdoor base‑station cabinets and harsh field environments.

Q: Which 5G fronthaul protocols are supported?

A: Supports CPRI‑Option10 at 24.33024Gbps and eCPRI at 25.78125Gbps for BBU‑RRU 5G fronthaul interconnection.
