Extreme compatible MGBIC-BX120-U Description

Compatible Extreme Networks MGBIC-BX120-U is Multi-Vendor MSA Compatible SFP (Small Form factor Pluggable) Transceiver, operating over Single Fiber Single-Mode Fiber (SMF) optical cable. It has minimum guaranteed optical budget of 22 dB, with in most cases is enough to reach about 80 km distance. However, distance is just indicative parameter calculated for comfort of identification. Eventually we calculate distance taking in account minimal optical budget and average attenuation of optical cabling in industry. This transceiver use top quality DFB Laser transmitter with operating at nominal wavelength 1490 nm. and 1550 nm. PIN Photodiode receiver. It support DDM/DOM optical diagnostics, with provide diagnostic information about the present operating conditions. Extreme Networks MGBIC-BX120-U operates in Industrial -45°C - +85°C temperature range and has Single LC interface. SFP support 1.063-1.25Gbps data rate and such applications as Gigabit Ethernet (1.25 Gbps)|1G Fiber Channel (1.0625 Gbps). Compatible Extreme Networks MGBIC-BX120-U SFP Single Fiber optical transceiver is multi-purpose module used in number of different places of today’s networking. Consequently, most popular applications are Gigabit Ethernet communication links in extreme industrial environment, Enterprise LAN & SAN Networks with high or low environment temperature demand, Data Center LAN & SAN Networks and other optical links.

Transceiver is CE/RoHS certified and it is Compliant with product safety standards. Extreme Networks MGBIC-BX120-U SFP Transceiver is fully compliant to SFP Multi Source Agreement INF-8074i. Consequently, it means that module is compatible with 80% of networking equipment, where is not implemented a special algorithm for protection against third party modules. However – we can provide SFP transceiver with custom-encoded firmware in order to make it work almost in any equipment. Therefore, we will be glad to know what your requirement is. Because our focus is providing top quality service, we are performing serious quality checks before delivery of our products. As a result, we do optical parameter measurements, connector cleanness tests and SFP transceiver EEPROM memory data validation tests. We will be glad to know your requirements - Contact us.
