GIGALIGHT 25G SFP28 ZR 80km

• Both TOSA (Transmitter Optical Sub-Assembly) and ROSA (Receiver Optical Sub-Assembly) utilize hermetically sealed packaging for stability and reliability, meeting telecom-grade application requirements.
• The TOSA employs an EML (Electro-Absorption Modulated Laser) 1310nm laser with TEC (Thermo-Electric Cooler) cooling.
• The ROSA integrates a PIN photodiode and SOA (Semiconductor Optical Amplifier) to provide a 30dB optical budget.
• Supports 80km dual-fiber single-mode transmission with host RS-FEC (Reed-Solomon Forward Error Correction) enabled.
• Product power consumption is less than 2.5W.

GIGALIGHT 40G QSFP+ ZR4 80km

• Both TOSA and ROSA utilize hermetically sealed packaging for stability and reliability, meeting telecom-grade application requirements.
• The TOSA uses a 4-wavelength LAN-WDM DML (Directly Modulated Laser) with TEC cooling.
• The ROSA employs a high-sensitivity APD (Avalanche Photodiode) optical detector to provide a 28dB optical budget.
• Supports 80km dual-fiber single-mode transmission.
• Product power consumption is less than 4.5W.

GIGALIGHT 100G QSFP28 BIDI ZR4 80km

• Both TOSA and ROSA utilize hermetically sealed packaging for stability and reliability, meeting telecom-grade application requirements.
• Designed with 8-wavelength LAN-WDM BIDI (Bidirectional) technology, used in pairs.
• The TOSA uses a 4-wavelength EML LAN-WDM laser with TEC cooling.
• The ROSA integrates a PIN photodiode and SOA to provide a 30dB optical budget.
• Supports 80km single-fiber single-mode transmission with host RS-FEC enabled.
• Built-in 4×25G CDR (Clock and Data Recovery).
• Product power consumption is less than 6.5W.

GIGALIGHT has always been committed to providing high-performance, high-quality, and reliable optical communication solutions to global customers. The launch of the 25G SFP28 ZR, 40G QSFP+ ZR4, and 100G QSFP28 ZR4 BIDI optical transceivers will further enhance GIGALIGHT's market competitiveness in ultra-long-haul telecom-grade applications, providing even better optical transmission solutions for 5G communications, telecom, and metropolitan area transmission applications.
