25G BASE SFP28 Transceiver Module

X-Krama's 25G optical modules are low-speed optical modules in the optical module market. The emergence

of 25G optical modules compensates to a certain extent for the high price of high-speed optical modules while the

speed of 10G optical modules cannot meet the needs of users.

The 25G SFP28 optical module is mainly used for the interconnection of data center servers and switches. It is

a new Ethernet standard with multiple advantages. It was proposed by the IEEE 802.3 working group in July 2014

and was revised in June 2016. complete. The biggest advantage that 25G Ethernet technology brings to data

centers is that it can maximize bandwidth and port density, and it can also use 25Gb/s single-channel physical

layer technology to achieve 100Gb data transmission, and it can provide the most energy-efficient Ways to meet

the increasing demands of next-generation data center networks.

Features :

Supports up to 25.78Gb/s data rates
Transmission up to 40km on 9/125μm SMF
EML transmitter and APD photo-detector
Duplex LC connector
Internal CDR on both transmitter and receiver
Digital diagnostics functions are available via the I2C interface
Electrical interface specifications per SFF-8431
Management interface specifications per SFF-8432 and SFF-8472
Hot-pluggable SFP28 footprint
Low power dissipation
Metal enclosure, for lower EMI
RoHS compliant and lead-free
Single +3.3V power supply
Operating case temperature: Standard : 0 to +70°C / Industrial : -40 to +85°C

Applications :

25G Ethernet
CPRI Option 10
Data Center
WDM System
High-speed storage area networks
