Q: Are you a manufacturer or a trading company?
A: Since 2013, we have been a manufacturer specializing in telecommunications equipment. We are ISO9001:2015 certified and recognized as a National High-Tech Enterprise with a reputation for integrity.
Q: What models of 25G SFP28 optical modules are available?
A: Standard 25G SFP28 optical modules include SR, LR, and ER types. The 25G SFP28 SR optical module operates at a wavelength of 850nm and features a Vertical-Cavity Surface-Emitting Laser (VCSEL) transmitter, necessitating the use of 50/125μm OM3/OM4 multimode fibers. It provides transmission distances of 70 meters with OM3 and 100 meters with OM4. The 25G SFP28 LR and 25G SFP28 ER are single-mode modules, requiring OS2 single-mode fiber patch cords for operation.
25G SFP28 color optical modules encompass CWDM SFP28 and DWDM SFP28 modules. The 25G CWDM SFP28 operates within the wavelength range of 1271-1331nm and is primarily utilized in 5G front-haul transmission networks, capable of reaching up to 10 kilometers over OS2 single-mode fiber.
Q: What is the maximum transmission distance for a 25G SFP28 transceiver?
A: Presently, the theoretical maximum transmission distance achievable is 40 kilometers.
Q: Does the SFP28 optical module support backward compatibility?
A: Yes, it supports backward compatibility with 10G rates.
Q: Can an SFP28 port interconnect with a QSFP28 port?
A: Yes, they can be interconnected, utilizing either a module plus jumper or a breakout cable method.
- For the module+jumper configuration: The 25G end employs a 25G SR module, while the 100G end uses a 100G SR4 module, interconnected by a multimode MTP/MPO to 4xLC harness cable.
- For the breakout cable approach: A 100G to 4x25G breakout AOC/DAC cable is employed for interconnection.
