The H9MO-LM63 comes in two versions. The standard H9MO-LM63 operates on a single power module, with a number of voltage options, while the dual power version, H9MO-LM63RP, provides both input power feed and internal power module redundancy for added operation reliability, but only supports -48V DC inputs. Both have a range of other options to suit application needs.

Ordering information for H9MO-LM63 and H9MO-LM63RP can be specified as:

H9MO-LM63/options       and        H9MO-LM63RP/options

where ‘options’ is a variable length string of option symbols.

Table 1.2-1 Options available to both H9MO-LM63 and H9MO-LM63RP:

Table 1.2-2Options specific to H9MO-LM63:

Therefore, H9MO-LM63 without options indicate a device with a single STM-1 port, SC connector, dual fiber transmission, normal transmission distance, 1310nm transmission wavelength, 75W E1 ports, and 100~240V AC power supply.

To specify options other than the defaults, for example, STM-1 protection, -48V DC power supply, and 120W E1 interface, the ordering information should look like:

H9MO-LM63/8PT

Note that the position of each option symbol in the sequence is not significant.
