MGBLH1 is the Cisco 1000BASE-LH SFP transceiver for single-mode fiber, 1310 nm wavelength, supporting up to 40 km. It is part of the Cisco MGE small business SFP range and uses a duplex LC connector for both transmit and receive.
Average output power is -4 dBm to 0 dBm, receiver sensitivity is typically -25 dBm and receiver overload is -3 dBm. Maximum power consumption is 1 W. The module measures 13.4 x 8.5 x 56.5 mm (0.53 x 0.33 x 2.22 in) and weighs 0.018 kg (0.63 oz).
Compliance covers FCC Part 15 Class B, EN55022 Class B and VCCI Class B for emissions, and FDA 21 CFR 1040.10 and 1040.11, EN60950 and EN (IEC) 60825-1 and 2 for safety. Humidity tolerance is 10 to 85 percent, noncondensing.
The minimum requirement for the host is a switch with an SFP port. The MGE modules are used in Cisco 110, 220, 250, 350, 350X and 550X Series switches. MGBLH1 is the 40 km LH part, while MGBLX1 is the 10 km LX part.
