What is the difference between 100GE ER4 and OTU4 operation?

100GE ER4 is designed for Ethernet transmission following IEEE 802.3 standards, while OTU4 is an optical transport standard defined by ITU-T for carrier-grade networks. This CFP2 ER4 module supports both operating modes through dual-rate capability.

Why does this module support both 100GE and OTU4 data rates?

Supporting dual-rate operation allows network operators to deploy the same optical module across different environments, reducing inventory requirements and improving flexibility when integrating Ethernet and optical transport systems.

What optical technology enables the 40km transmission distance?

The module uses LAN-WDM wavelength technology combined with a high-performance PIN receiver with SOA amplification. This design provides the optical power budget required for long-distance transmission over single-mode fiber.

Can this CFP2 ER4 module work with existing 100G network equipment?

Yes. The module is designed with a standard CAUI-4 electrical interface and CFP2 form factor, making it compatible with many 100G Ethernet switches, routers, and optical transport platforms that support CFP2 modules.

What monitoring functions are available through the MDIO interface?

The MDIO interface provides access to digital diagnostic information, allowing operators to monitor module status, optical parameters, and operational conditions for easier maintenance and troubleshooting.
